       a couple of months ago I found a piece of Galena on the Thames foreshore, in an area where we also find lots of lead waste drippings, presumably from making lead cloth seals, which we also find lots of. Galena is the natural mineral form of lead sulphide, PbS, the most important ore of lead. has a melting point low enough to be smelted over wood fire. it’s not local to London. I wonder if this piece was destined for a cloth seal but missed the crucible a few hundred years ago. #mudlarking
