In the years before McDonalds and 8-Track tapes, sulfuric acid was the staple used in all tanning. Just remember, pour the acid IN THE WATER, not the water in the acid.


You can use it................but!

Yes - it can be used in a pickle. Leather Tanneries use it - but they also tan with Chrome which eliminates any residual Sulphate being left the skin later. It's okay to use it when Chrome tanning but for other tans you are simply loading them up with sulphate that later draws moisture and turns back into Sulphuric Acid - which weakens the skin with age.

I also prefer Formic over Sulphuric simply because the Formic pickled skins have more plump to them for easier shaving. Sulphuric pickled skins do not.
