After gainning a little and i stress little experience with tanning, i wonder where the different tans come from. I wonder if, in the leather industry, there are different recipes for tans depending upon the use of the leather. Tans xxand x provide this type of finished product while rr and r provide this type. I know this is a taxidermy site but was curious if anyone knows. I have witnessed differing results from the few tans ive tried. Some, i feel, do indeed make leather but it seems to be a leather that isnt taxidermy friendlt. A coarse less stretchy leather has its place for sure. I dont know -just got curious. If i ever go into making baseball gloves i have an idea of a good tan. I have found a very taxidermy friendly tan(stoked about that)i find different tans to be very interesting. Any thoughts?
