| One thing about rust, salt and moisture: salts deliquescence.
| I.e. they absorb moisture from air until there is enough liquid
| to dissolve themselves in. This happens below 100% relative
| humidity (around 75% for common salt, but as little as 31% for
| cacl2). So salt-contaminated surfaces can easily get wet even
| when the air is not that humid, bad news for steel!

| Great article. Cross roads between old, daily life, technical.

| The ongoing maintenance budget for the statue these days, I'm

| million is not entirely spent, the remainder is banked so that
| the fund will become sufficient over time to pay for a major
| overhaul.

|
| even in this case, the only way you could really "spend" the
| sheets is by removing the roof and walls of your house, so
| until you have some extra, unneeded ones, they aren't really
| money. they're more a store of value; an analogue might be
| buying artwork that you know you could sell later if you needed
| the money.
