Cuspidor Powder.
—Peat rubble is ground to a powder, and 100 parts put into a mixing machine, which can be hermetically sealed. Then 15 parts of blue vitriol are added either very finely pulverized or in a saturated aqueous solution. Next are added 2 parts of formalin, and lastly 1 part of ground cloves, orange peel, or a sufficient quantity of some volatile oil, to give the desired perfume. The mixing machine is then closed, and kept at work until the constituents are perfectly mixed; the powder is then ready to be put up for the market. Its purpose is to effect a rapid absorption of the sputum, with simultaneous destruction of any microbes present, and to prevent decomposition and consequent unpleasant odors.
Deodorants For Water-closets.—
I.— Ferric chloride  4 parts
Zinc chloride  5 parts
Aluminum chloride  5 parts
Calcium chloride  4 parts
Magnesium chloride  3 parts
Water sufficient to make 90 parts

Dissolve, and add to each gallon 10 grains thymol and 1/4 ounce oil of rosemary, previously dissolved in about 6 quarts of alcohol, and filter.

II.— Sulphuric acid, fuming    90 parts
Potassium permanganate    45 parts
Water 4,200 parts

Dissolve the permanganate in the water, and add under the acid. This is said to be a most powerful disinfectant, deodorizer, and germicide. It should not be used where there are metal trimmings.

Formaldehyde For Disinfecting Books, Papers, Etc.
—The property of formaldehyde of penetrating all kinds of paper, even when folded together in several layers, may be utilized for a perfect disinfection of books and letters, especially at a temperature of 86° to 122° F. in a closed room. The degree of penetration as well as the disinfecting power of the formaldehyde depend upon the method of generating the gas. Letters, paper in closed envelopes, are completely disinfected only in 12 hours, books in 24 hours at a temperature of 122° F. when 70 cubic centimeters of formo-chloral—17.5 g. of gas—per cubic meter of space are used. Books must be stood up in such a manner that the gas can enter from the sides. Bacilli of typhoid preserve their vitality longer upon unsized paper and on filtering paper than on other varieties.

There is much difference of opinion as to the disinfecting and deodorizing power of formaldehyde when used to disinfect wooden tierces. While some have found it to answer well, others have got variable results, or failed of success. The explanation seems to be that those who have obtained poor results have not allowed time for the disinfectant to penetrate the pores of the wood, the method of application being wrong. The solution is thrown into the tierce, which is then steamed out at once, whereby the aldehyde is volatilized before it has had time to do its work. If the formal and the steam, instead of being used in succession, were used together, the steam would carry the disinfectant into the pores of the wood. But a still better plan is to give the aldehyde more time. {264}

Another point to be remembered in all cases of disinfection by formaldehyde is that a mechanical cleansing must precede the action of the antiseptic. If there are thick deposits of organic matter which can be easily dislodged with a scrubbing brush, they can only be disinfected by the use of large quantities of formaldehyde used during a long period of time.

General Disinfectants.—
I.— Alum 10 ounces
Sodium carbonate 10 ounces
Ammonium chloride  2 ounces
Zinc chloride  1 ounce
Sodium chloride  2 ounces
Hydrochloric acid, quantity sufficient.
Water to make  1 gallon.

Dissolve the alum in one half gallon of boiling water, and add the sodium carbonate; then add hydrochloric acid until the precipitate formed is dissolved. Dissolve the other salt in water and add to the previous solution. Finally add enough water to make the whole measure 1 gallon, and filter.

In use, this is diluted with 7 parts of water.

II.—For the Sick Room.—In using this ventilate frequently: Guaiac, 10 parts; eucalyptol, 8 parts; phenol, 6 parts; menthol, 4 parts; thymol, 2 parts; oil of cloves, 1 part; alcohol of 90 per cent, 170 parts.

Atomizer Liquid for Sick Rooms.—

by weight
III.— Eucalyptol  10 parts
Thyme oil   5 parts
Lemon oil   5 parts
Lavender oil   5 parts
Spirit, 90 per cent 110 parts

To a pint of water a teaspoonful for evaporation.

Non-Poisonous Sheep Dips.—Paste.—

I.— Creosote (containing 15 per cent to 20 per cent of carbolic acid) 2 parts
Stearine or Yorkshire grease specific gravity, 1340 1 part
Black rosin, 5 per cent to 10 per cent.

Melt the rosin and add grease and soda lyes, and then add creosote cold.

II.— Creosote 1 part
Crude hard rosin oil 1 part

Put rosin oil in copper and heat to about 220° F., and add as much caustic soda powder, 98 per cent strength, as the oil will take up. The quantity depends upon the amount of acetic acid in the oil. If too much soda is added it will remain at the bottom. When the rosin oil has taken up the soda add creosote, and let it stand.

Odorless Disinfectants.—
I.— Ferric chloride  4 parts
Zinc chloride  5 parts
Aluminum chloride  5 parts
Calcium chloride  4 parts
Manganese chloride  3 parts
Water 69 parts

If desired, 10 grains thymol and 2 fluidrachms oil of rosemary, previously dissolved in about 12 fluidrachms of alcohol, may be added to each gallon.

II.— Alum  10 parts
Sodium carbonate  10 parts
Ammonium chloride   2 parts
Sodium chloride   2 parts
Zinc chloride   1 part
Hydrochloric acid, sufficient.
Water 100 parts

Dissolve the alum in about 50 parts boiling water and add the sodium carbonate. The resulting precipitate of aluminum hydrate dissolve with the aid of just sufficient hydrochloric acid, and add the other ingredients previously dissolved in the remainder of the water.

III.— Mercuric chloride     1 part
Cupric sulphate    10 parts
Zinc sulphate    50 parts
Sodium chloride    65 parts

—The disinfectant known by this name is a mixture made from the following recipe:
Zinc sulphate 49 parts
Ammonia alum 49 parts
Potash permanganate  1 part
Lime  1 part

The ingredients are fused together, mixed with a little calcium chloride, and perfumed with thymol.

Platt’s Chlorides.—
I.— Aluminum sulphate 6 ounces
Zinc chloride 1 1/2 ounces
Sodium chloride 2 ounces
Calcium chloride 3 ounces
Water enough to make 2 pints.

II.—A more elaborate formula for a preparation said to resemble the proprietary article is as follows: {265}

Zinc, in strips  4 ounces
Lead carbonate  2 ounces
Chlorinated lime  1 ounce
Magnesium carbonate    1/2 ounce
Aluminum hydrate  1 1/2 ounces
Potassium hydrate    1/2 ounce
Hydrochloric acid 16 ounces
Water 16 ounces
Whiting, enough.

Dissolve the zinc in the acid; then add the other salts singly in the order named, letting each dissolve before the next is added. When all are dissolved add the water to the solution, and after a couple of hours add a little whiting to neutralize any excess of acid; then filter.

Zinc chloride ranks very low among disinfectants, and the use of such solutions as these, by giving a false sense of security from disease germs, may be the means of spreading rather than of checking the spread of sickness.

Disinfecting Coating.
—Carbolic acid, 2 parts; manganese, 3 parts; calcium chloride, 2 parts; china clay, 10 parts; infusorial earth, 4 parts; dextrin, 2 parts; and water, 10 parts.

DOG BISCUIT.

The waste portions of meat and tallow, including the skin and fiber, have for years been imported from South American tallow factories in the form of blocks. Most of the dog bread consists principally of these remnants, chopped and mixed with flour. They contain a good deal of firm fibrous tissue, and a large percentage of fat, but are lacking in nutritive salts, which must be added to make good dog bread, just as in the case of the meat flour made from the waste of meat extract factories. The flesh of dead animals is not used by any reputable manufacturers, for the reason that it gives a dark color to the dough, has an unpleasant odor, and if not properly sterilized would be injurious to dogs as a steady diet.

Wheat flour, containing as little bran as possible, is generally used, oats, rye, or Indian meal being only mixed in to make special varieties, or, as in the case of Indian meal, for cheapness. Rye flour would give a good flavor, but it dries slowly, and the biscuits would have to go through a special process of drying after baking, else they would mold and spoil. Dog bread must be made from good wheat flour, of a medium sort, mixed with 15 or 16 per cent of sweet, dry chopped meat, well baked and dried like pilot bread or crackers. This is the rule for all the standard dog bread on the market. There are admixtures which affect more or less its nutritive value, such as salt, vegetables, chopped bones, or bone meal, phosphate of lime, and other nutritive salts. In preparing the dough and in baking, care must be taken to keep it light and porous.

DOSES FOR ADULTS AND CHILDREN.

The usual method pursued by medical men in calculating the doses of medicine for children is to average the dose in proportion to their approximate weight or to figure out a dose upon the assumption that at 12 years of age half of an adult dose will be about right. Calculated on this basis the doses for those under 12 will be in direct proportion to the age in years plus 12, divided into the age. By this rule a child 1 year old should get 1 plus 12, or 13, dividing 1, or 1/13 of an adult dose. If the child is 2 years old it should get 2 plus 12, or 14, dividing 2, or 1/7 of an adult dose. A child of 3 years should get 3 plus 12, or 15, dividing 3, or 1/5 of an adult dose. A child of 4 should get 4 plus 12, or 16, dividing 4, or 1/4 of an adult dose.

As both children and adults vary materially in size when of the same age the calculation by approximate weights is the more accurate way. Taking the weight of the average adult as 150 pounds, then a boy, man, or woman, whatever the age, weighing only 75 pounds should receive only one-half of an adult dose, and a man of 300 pounds, provided his weight is the result of a properly proportioned body, and not due to mere adipose {266} tissue, should be double that of the average adult. If the weight is due to mere fat or to some diseased condition of the body, such a calculation would be entirely wrong. The object of the calculation is to get as nearly as possible to the amount of dilution the dose undergoes in the blood or in the intestinal contents of the patient. Each volume of blood should receive exactly the same dose in order to give the same results, other conditions being equal.

DRAWINGS, PRESERVATION OF.

Working designs and sketches are easily soiled and rendered unsuitable for further use. This can be easily avoided by coating them with collodion, to which 24 per cent of stearine from a good stearine candle has been added. Lay the drawing on a glass plate or a board, and pour on the collodion, as the photographer treats his plates. After 10 or 20 minutes the design will be dry and perfectly white, possessing a dull luster, and being so well protected that it may be washed off with water without fear of spoiling it.

DYES

In accordance with the requirements of dyers, many of the following recipes describe dyes for large quantities of goods, but to make them equally adapted for the use of private families they are usually given in even quantities, so that it is an easy matter to ascertain the quantity of materials required for dyeing, when once the weight of the goods is known, the quantity of materials used being reduced in proportion to the smaller quantity of goods.

Employ soft water for all dyeing purposes, if it can be procured, using 4 gallons water to 1 pound of goods; for larger quantities a little less water will do. Let all the implements used in dyeing be kept perfectly clean. Prepare the goods by scouring well with soap and water, washing out the soap well, and dipping in warm water, before immersion in the dye or mordant. Goods should be well aired, rinsed, and properly hung up after dyeing. Silks and fine goods should be tenderly handled, otherwise injury to the fabric will result.

Aniline Black.

—Water, 20 to 30 parts; chlorate of potassa, 1 part; sal ammoniac, 1 part; chloride of copper, 1 part; aniline and hydrochloric acid, each 1 part, previously mixed together. It is essential that the preparation should be acid, and the more acid it is the more rapid will be the production of the blacks; if too much so, it may injure the fabric. The fabric or yarn is dried in ageing rooms at a low temperature for 24 hours, and washed afterwards.

Black On Cotton.

—For 40 pounds goods, use sumac, 30 pounds; boil 3/4 of an hour; let the goods steep overnight, and immerse them in limewater, 40 minutes, remove, and allow them to drip 3/4 of an hour; add copperas, 4 pounds, to the sumac liquor, and dip 1 hour more; next work them through limewater for 20 minutes; then make a new dye of logwood, 20 pounds, boil 2 1/2 hours, and enter the goods 3 hours; then add bichromate of potash, 1 pound, to the new dye, and dip 1 hour more. Work in clean cold water and dry out of the sun.

Black Straw Hat Varnish.

—Best alcohol, 4 ounces; pulverized black sealing wax, 1 ounce. Place in a phial, and put the phial into a warm place, stirring or shaking occasionally until the wax is dissolved. Apply it when warm before the fire or in the sun. This makes a beautiful gloss. {267}

Chrome Black For Wool.

—For 40 pounds of goods, use blue vitriol, 3 pounds; boil a short time, then dip the wool or fabric 3/4 of an hour, airing frequently. Take out the goods, and make a dye with logwood, 24 pounds; boil 1/2 hour, dip 3/4 of an hour, air the goods, and dip 1/4 of an hour longer; then wash in strong soapsuds. A good fast color.

Black Dye On Wool, For Mixtures.

—For 50 pounds of wool, take bichromate of potash, 1 pound, 4 ounces; ground argal, 15 ounces; boil together and put in the fabric, stirring well, and let it remain in the dye 5 hours. Take it out, rinse slightly in clean water, then make a new dye, into which put logwood, 1 1/2 pounds. Boil 1 1/4 hours, adding chamber lye, 5 pints. Let the fabric remain in all night, and wash out in clean water.

Bismarck Brown.

—Mix together 1 pound Bismarck, 5 gallons water, and 3/4 pound sulphuric acid. This paste dissolves easily in hot water and may be used directly for dyeing. A liquid dye may be prepared by making the bulk of the above mixture to 2 gallons with alcohol. To dye, sour with sulphuric acid; add a quantity of sulphate of soda, immerse the wool, and add the color by small portions, keeping the temperature under 212° F. Very interesting shades may be developed by combining the color with indigo paste or picric acid.

Chestnut Brown For Straw Bonnets.

—For 25 hats, use ground sanders, 1 1/2 pounds; ground curcuma, 2 pounds; powdered gallnuts or sumac, 3/4 pound; rasped logwood, 1/10 pound. Boil together with the hats in a large kettle (so as not to crowd), for 2 hours, then withdraw the hats, rinse, and let them remain overnight in a bath of nitrate of 4° Bé., when they are washed. A darker brown may be obtained by increasing the quantity of sanders. To give the hats the desired luster, they are brushed with a brush of couchgrass, when dry.

Cinnamon Or Brown For Cotton And Silk.

—Give the goods as much color, from a solution of blue vitriol, 2 ounces, to water, 1 gallon, as they will take up in dipping 15 minutes; then turn them through limewater. This will make a beautiful sky blue of much durability. The fabric should next be run through a solution of prussiate of potash, 1 ounce, to water, 1 gallon.

Brown Dye For Cotton Or Linen.

—Give the pieces a mixed mordant of acetate of alumina and acetate of iron, and then dye them in a bath of madder, or madder and fustic. When the acetate of alumina predominates, the dye has an amaranth tint. A cinnamon tint is obtained by first giving a mordant of alum, next a madder bath, then a bath of fustic, to which a little green copperas has been added.

Brown For Silk.

—Dissolve annatto, 1 pound; pearlash, 4 pounds, in boiling water, and pass the silk through it for 2 hours; then take it out, squeeze well, and dry. Next give it a mordant of alum, and pass through a bath of brazil wood, and afterwards through a bath of logwood, to which a little green copperas has been added; wring it out and dry; afterwards rinse well.

Brown Dye For Wool.

—This may be induced by a decoction of oak bark, with variety of shade according to the quantity employed. If the goods be first passed through a mordant of alum the color will be brightened.

Brown For Cotton.

—Catechu or terra japonica gives cotton a brown color; blue vitriol turns it to the bronze; green copperas darkens it, when applied as a mordant and the stuff is boiled in the bath. Acetate of alumina as a mordant brightens it. The French color Carmelite is given with catechu, 1 pound; verdigris, 4 ounces; and sal ammoniac, 5 ounces.

Dark Snuff Brown For Wool.

—For 50 pounds of goods, take camwood, 10 pounds, boil for 20 minutes, then dip the goods for 3/4 of an hour; take them out, and add to the dye, fustic, 25 pounds, boil 12 minutes, and dip the goods 3/4 of an hour; then add blue vitriol, 10 ounces, copperas, 2 pounds, 8 ounces; dip again 40 minutes. Add more copperas if the shade is required darker.

Brown For Wool And Silk.

—Infusion or decoction of walnut peels dyes wool and silk a brown color, which is brightened by alum. Horse-chestnut peels also impart a brown color; a mordant of muriate of tin turns it on the bronze, and sugar of lead the reddish brown.

Alkali Blue And Nicholson’s Blue.

—Dissolve 1 pound of the dye in 10 gallons boiling water, and add this by small portions to the dye bath, which should be rendered alkaline by borax. The fabric should be well worked about between each addition of the color. The temperature must be kept under 212° F. To develop the color, wash with water {268} and pass through a bath containing sulphuric acid.

Aniline Blue.

—To 100 pounds of fabric, dissolve 1 1/4 pounds aniline blue in 3 quarts hot alcohol, strain through a filter, and add it to a bath of 130° F.; also 10 pounds Glauber’s salts, and 5 pounds acetic acid. Immerse the goods and handle them well for 20 minutes. Next heat slowly to 200° F.; then add 5 pounds sulphuric acid diluted with water. Let the whole boil 20 minutes longer; then rinse and dry. If the aniline be added in 2 or 3 proportions during the process of coloring, it will facilitate the evenness of the color.

Blue On Cotton.

—For 40 pounds of goods, use copperas, 2 pounds; boil and dip 20 minutes; dip in soapsuds, and return to the dye 3 or 4 times; then make a new bath with prussiate of potash, 1/2 pound; oil of vitriol, 1 1/4 pints; boil 1/2 hour, rinse out and dry.

Sky Blue On Cotton.

—For 60 pounds of goods, blue vitriol, 5 pounds. Boil a short time, then enter the goods, dip 3 hours, and transfer to a bath of strong limewater. A fine brown color will be imparted to the goods if they are then put through a solution of prussiate of potash.

Blue Dye For Hosiery.

—One hundred pounds of wool are colored with 4 pounds Guatemala or 3 pounds Bengal indigo, in the soda or wood vat. Then boil in a kettle a few minutes, 5 pounds of cudbear or 8 pounds of archil paste; add 1 pound of soda, or, better, 1 pail of urine; then cool the dye to about 170° F. and enter the wool. Handle well for about 20 minutes, then take it out, cool, rinse, and dry. It makes no difference whether the cudbear is put in before or after the indigo. Three ounces of aniline purple dissolved in alcohol, 1/2 pint, can be used instead of the cudbear. Wood spirit is cheaper than alcohol, and is much used by dyers for the purpose of dissolving aniline colors. It produces a very pretty shade, but should never be used on mixed goods which have to be bleached.

Dark-blue Dye.

—This dye is suitable for thibets and lastings. Boil 100 pounds of the fabric for 1 1/2 hours in a solution of alum, 25 pounds; tartar, 4 pounds; mordant, 6 pounds; extract of indigo, 6 pounds; cool as usual. Boil in fresh water from 8 to 10 pounds of logwood, in a bag or otherwise, then cool the dye to 170° F. Reel the fabric quickly at first, then let it boil strongly for 1 hour. This is a very good imitation of indigo blue.

Saxon Blue.

—For 100 pounds thibet or comb yarn, use alum, 20 pounds; cream of tartar, 3 pounds; mordant, 2 pounds; extract of indigo, 3 pounds; or carmine, 1 pound, makes a better color. When all is dissolved, cool the kettle to 180° F.; enter and handle quickly at first, then let the fabric boil 1/2 hour, or until even. Long boiling dims the color. Zephyr worsted yarn ought to be prepared, first, by boiling it in a solution of alum and sulphuric acid; the indigo is added afterwards.

Logwood And Indigo Blue.

—For 100 pounds of cloth. Color the cloth first by one or two dips in the vat of indigo blue, and rinse it well, and then boil it in a solution of 20 pounds of alum, 2 pounds of half-refined tartar, and 5 pounds of mordant, for 2 hours; finally take it out and cool. In fresh water boil 10 pounds of good logwood for half an hour in a bag or otherwise; cool off to 170° F. before entering. Handle well over a reel, let it boil for half an hour; then take it out, cool and rinse. This is a very firm blue.

Blue Purple For Silk.

—For 40 pounds of goods, take bichromate of potash, 8 ounces; alum, 1 pound; dissolve all and bring the water to a boil, and put in the goods; boil 1 hour. Then empty the dye, and make a new dye with logwood, 8 pounds, or extract of logwood, 1 pound 4 ounces, and boil in this 1 hour longer. Grade the color by using more or less logwood, as dark or light color is wanted.

Blue Purple For Wool.

—One hundred pounds of wool are first dipped in the blue vat to a light shade, then boiled in a solution of 15 pounds of alum and 3 pounds of half-refined tartar, for 1 1/2 hours, the wool taken out, cooled, and let stand 24 hours. Then boil in fresh water 8 pounds of powdered cochineal for a few minutes, cool the kettle to 170° F. Handle the prepared wool in this for 1 hour, when it is ready to cool, rinse and dry. By coloring first with cochineal, as aforesaid, and finishing in the blue vat, the fast purple or dahlia, so much admired in German broadcloths, will be produced. Tin acids must not be used in this color.

To Make Extract Of Indigo Blue.

—Take of vitriol, 2 pounds, and stir into it finely pulverized indigo, 8 ounces, stirring briskly for the first half hour; then {269} cover up, and stir 4 or 5 times daily for a few days. Add a little pulverized chalk, stirring it up, and keep adding it as long as it foams; it will neutralize the acid. Keep it closely corked.

Light Silver Drab.

—For 50 pounds of goods, use logwood, 1/2 pound; alum, about the same quantity; boil well, enter the goods, and dip them for 1 hour. Grade the color to any desired shade by using equal parts of logwood and alum.

Gray Dyes:

Slate Dye For Silk.
—For a small quantity, take a pan of warm water and about a teacupful of logwood liquor, pretty strong, and a piece of pearlash the size of a nut; take gray-colored goods and handle a little in this liquid, and it is finished. If too much logwood is used, the color will be too dark.
Slate For Straw Hats.
—First, soak in rather strong warm suds for 15 minutes to remove sizing or stiffening; then rinse in warm water to get out the soap. Scald cudbear, 1 ounce, in sufficient water to cover the hat; work it in this dye at 180° F., until a light purple is obtained. Have a vessel of cold water, blued with the extract of indigo, 1/2 ounce, and work or stir the bonnet in this until the tint pleases. Dry, then rinse out with cold water, and dry again in the shade. If the purple is too deep in shade the final slate will be too dark.
Silver Gray For Straw.
—For 25 hats, select the whitest hats and soften them in a bath of crystallized soda to which some clean limewater has been added. Boil for 2 hours in a large vessel, using for a bath a decoction of the following: Alum, 4 pounds; tartaric acid, 3/8 pound; some ammoniacal cochineal, and carmine of indigo. A little sulphuric acid may be necessary in order to neutralize the alkali of the cochineal dye. If the last-mentioned ingredients are used, let the hats remain for an hour longer in the boiling bath, then rinse in slightly acidulated water.
Dark Steel.
—Mix black and white wool together in the proportion of 50 pounds of black wool to 7 1/2 pounds of white. For large or small quantities, keep the same proportion, mixing carefully and thoroughly.

Green Dyes:

Aniline Green For Silk.
—Iodine green or night green dissolves easily in warm water. For a liquid dye 1 pound may be dissolved in 1 gallon alcohol, and mixed with 2 gallons water, containing 1 ounce sulphuric acid.
Aniline Green For Wool.
—Prepare two baths, one containing the dissolved dye and a quantity of carbonate of soda or borax. In this the wool is placed, and the temperature raised to 212° F. A grayish green is produced, which must be brightened and fixed in a second bath of water 100° F., to which some acetic acid has been added. Cotton requires preparation by sumac.
Green For Cotton.
—For 40 pounds of goods, use fustic, 10 pounds; blue vitriol, 10 ounces; soft soap, 2 1/2 quarts; and logwood chips, 1 pound 4 ounces. Soak the logwood overnight in a brass vessel, and put it on the fire in the morning, adding the other ingredients. When quite hot it is ready for dyeing; enter the goods at once, and handle well. Different shades may be obtained by letting part of the goods remain longer in the dye.
Green For Silk.
—Boil green ebony in water, and let it settle. Take the clear liquor as hot as the hands can bear, and handle the goods in it until of a bright yellow. Take water and put in a little sulphate of indigo; handle goods in this till of the shade desired. The ebony may previously be boiled in a bag to prevent it from sticking to the silk.
Green For Wool And Silk.
—Take equal quantities of yellow oak and hickory bark, make a strong yellow bath by boiling, and shade to the desired tint by adding a small quantity of extract of indigo.
Green Fustic Dye.
—For 50 pounds of goods, use 50 pounds of fustic with alum, 11 pounds. Soak in water until the strength is extracted, put in the goods until of a good yellow color, remove the chips, and add extract of indigo in small quantities at a time, until the color is satisfactory.

Purple And Violet Dyes:

Aniline Violet And Purple.
—Acidulate the bath by sulphuric acid, or use sulphate of soda; both these substances render the shade bluish. Dye at 212° F. To give a fair middle shade to 10 pounds of wool, a quantity of solution equal to 1/2 to 3/4 ounces of the solid dye will be required. The color of the dyed fabric is improved by washing in soap and water, and then passing through a bath soured by sulphuric acid.
Purple.
—For 40 pounds of goods, use {270} alum, 3 pounds; muriate of tin, 4 teacups; pulverized cochineal, 1 pound; cream of tartar, 2 pounds. Boil the alum, tin, and cream of tartar, for 20 minutes, add the cochineal and boil 5 minutes; immerse the goods 2 hours; remove and enter them in a new dye composed of brazil wood, 3 pounds; logwood, 7 pounds; alum, 4 pounds, and muriate of tin, 8 cupfuls, adding a little extract of indigo.
Purple For Cotton.
—Get up a tub of hot logwood liquor, enter 3 pieces, give them 5 ends, and hedge out. Enter them in a clean alum tub, give them 5 ends, and hedge out. Get up another tub of logwood liquor, enter, give them 5 ends, and hedge out; renew the alum tub, give 5 ends in that, and finish.
Purple For Silk.
—For 10 pounds of goods, enter the goods in a blue dye bath, and secure a light-blue color, dry, and dip in a warm solution containing alum, 2 1/2 pounds. Should a deeper color be required, add a little extract of indigo.
Solferino And Magenta For Woolen, Silk, Or Cotton.
—For 1 pound of woolen goods, magenta shade, 96 grains, apothecaries’ weight, of aniline red, will be required. Dissolve in a little warm alcohol, using, say, 6 fluidounces, or about 6 gills alcohol per ounce of aniline. Many dyers use wood spirits because of its cheapness. For a solferino shade, use 64 grains aniline red, and dissolve in 4 ounces alcohol, to each 1 pound of goods. Cold water, 1 quart, will dissolve these small quantities of aniline red, but the cleanest and quickest way will be found by using the alcohol, or wood spirits. Clean the cloth and goods by steeping at a gentle heat in weak soapsuds, rinse in several masses of clean water and lay aside moist. The alcoholic solution of aniline is to be added from time to time to the warm or hot dye bath, till the color on the goods is of the desired shade. The goods are to be removed from the dye bath before each addition of the alcoholic solution, and the bath is to be well stirred before the goods are returned. The alcoholic solution should be first dropped into a little water, and well mixed, and the mixture should then be strained into the dye bath. If the color is not dark enough after working from 20 to 30 minutes, repeat the removal of the goods from the bath, and the addition of the solution, and the re-immersion of the goods from 15 to 30 minutes more, or until suited, then remove from the bath and rinse in several masses of clean water, and dry in the shade. Use about 4 gallons water for dye bath for 1 pound of goods; less water for larger quantities.
Violet For Silk Or Wool.
—A good violet dye may be given by passing the goods first through a solution of verdigris, then through a decoction of logwood, and lastly through alum water. A fast violet may be given by dyeing the goods crimson with cochineal, without alum or tartar, and after rinsing passing them through the indigo vat. Linens or cottons are first galled with 18 per cent of gallnuts, next passed through a mordant of alum, iron liquor, and sulphate of copper, working them well, then worked in a madder bath made with an equal weight of root, and lastly brightened with soap or soda.
