I was wondering is there another substitute for brains in tanning. What is it in brains that makes them so special?
It's the emulsified oils in the brains that gets into the fibers and prevents the little collagen lattice from setting back up between the fibers and making everything stiff.
Ivory soap (basically lard and lye), sliced thin and dissolved in water works well. I help out at Explore Park in the F&I fort, and Eddie Goode processes a number of skins there each year and that's what he usually uses. You can of course use brains, but eggs (lots of them) also works, as does Suagaro cactus seeds and jojoba berries. The key is the emulsified oils.
Most of the skins Eddie tans at Explore Park have been half-tanned. That is, they were fleshed, de-haired (usually bucked in a lye-water solution), scraped and dried. Basically they end up in a raw-hide state. Once dried like that they will keep indefinitely. That's how Virginia exported their buckskins to England prior to the Revolutionary War. As an export, it was second only to tobacco. Eddie makes the solution of natural soap and water (no detergents!) and works the stiff hide into it. Once it is wet again, he wrings it out and then starts the softening process.
Most of the deer were (and are) killed during cold weather, which is not conducive to braintanning. It was common to half-tan the hide when they harvested the deer in the fall and winter, and then turn it into leather in the spring when the weather was warmer. Takes about 1-hour labor to get it half-tanned and typically about another 5 or so to soften it into leather. Softening is easier in warm weather and takes longer when it's cold out. Once the leather is soft, you can smoke it to preserve it's softness and to color it.
If you're interested in Brain Tanning, do yourself a favor and get the book "Deerskins into Buckskins" by Matt Richards. Be sure to get the second edition as it has some extra info that makes the skins turn out luxuriously soft consistently. Use the link to Amazon from the board in the links section.
Hope this helps,
