i was browsing youtube a few years ago and saw a video that showed a guy fermenting tea bags in white vinegar and the result was oxalic acid which he used as wood stain. Was this fake or did he just make something else? if so how would i make some at home?
I've been trying for a month now to either extract or make KNO3 from things found in nature such as urine, ashes, soil ect. But I'm looking for a way to do this fast instead of a niter bed which would take over a year and so far all my attempts have failed. How do i do this?.
