Salt Alum Preservation Method
Alright, gather round the campfireātoday weāre tanning hides, not telling ghost stories. This is the alum tanning method, which is old-school, reliable, and pleasantly un-mystical once you know whatās actually going on. First, the big idea: alum tanning is alkaline. That means the pH runs high. This isnāt an acid pickle bath and it isnāt witchcraftāitās chemistry doing what chemistry does best: stabilizing collagen so your hide doesnāt rot, stink, or turn into heartbreak. Youāll want a five-gallon bucket with a lid. Drill a few breathing holes in that lid, or just place it on loosely to keep out extra dirt, insects, or curious pets. Add a 50/50 mix of salt and alum. If you use 2 lb of salt, add 2 lb of alum. If you use 5 lb of salt, add 5 lb of alum. In the video, I started with 2.5 lb of each, and I will be upping the mixture when more alum arrives to reach closer to 3ā5 lb total of each per bucket. Fine granular salt works best: pickling salt, feed-mixing salt, eating salt, even fancy sea salt. Then comes the star of the showāpickling alum. Three and a half pounds is about right, but you can use anywhere from 2ā5 lb as long as the mixture stays balanced. Youāll also want a long stick for stirring. A paint stick works. A clean branch works. Something that hasnāt recently been in contact with motor oil or existential regret. For drying later, grab a cheap sheet of plywood and a staple gun. Youāre not building furniture; youāre just giving the hide something to behave against. A sharp knife, fish-skinning pliers, and a little insurance in the form of curved needles and upholstery thread are smart additions. Holes happen. Even to careful people. Thatās life. Before anything touches water, make sure your hides are clean and properly scraped. Big chunks of meat and fat are not ārusticā; theyāre bacterial condos. Remove them. Your future self will thank you. If youāre unable to fully flesh right away, you can drop them in and flesh later while theyāre wet, or dry them and peel the silver skinābut they are more fragile that way. Iāll be testing a pressure-washer method as soon as it warms up a bit, then returning them to a fresh pickle.
