I remember reading in a economics and history book that sulphuric acid production was used as an alternative to gold standard as the basis of the value of currency due to it’s importance in making fertilizers; i.e, the money was backed by the production of sulphuric acid, but I cannot find the source towards that nor the book. The acid itself was not the medium of exchange if that was not clear.
It is entirely possible that my memory is making this up, so pardon if that is the case. Were it not, or were there an equivalent of money backed by manufactured good, and not on an extracted good. I would appreciate a source to that. Thank you.
