A Text-book of Assaying
Finished a textbook on mineral assaying. During the mining process, apparently it's usual to send a sample of some amount of ore to test for mineral content, I suppose mostly to determine whether processing the ore is worth the cost, and perhaps also to ensure the processing is going right or to know the quantity of chemical agents required for processing. So assaying is a bit like the mineral processing in miniature. Can't say I got much out of the chemistry behind it, though. Seems to me something you have to do in practice to learn.
