Recently I raised the topic of adding ammonia to snuff as a preservative. The encyclopaedia entry that I read was from around 1900.
Has anyone tried rehydrating old snuff with water and ammonia or just ammonia on its own ?
The reason that I am pondering it is I have read here that some people end up with mouldy snuff after their attempts at rehydration. I was thinking that the ammonia fumes might retard the growth of moulds.
