I just tanned my first batch of hides with Rittel’s EZ-100 and they didn’t turn out very well. I hope someone can help troubleshoot what went wrong because I’m determined to get it right. Our batch was 13 muskrats and 2 coons, fleshed and flint dried. We used Ultra-Soft relaxer, Safetee acid pickle for 5 days, neutralized, tanned 22hrs. Kept a careful watch on the pH of both the pickle (less than 2.0) and tan (4.0-4.2). We worked hard to break them as they dried. The hides are tanned but not very soft at all, they are crinkly and noisy when you bend them. They are flexible enough you can turn them right-side out and back again, but they don’t drape well, or feel nice enough to sew with, which was my intention. So here are some thoughts: how soft can EZ-100 make the leather? Are my expectations too high? I have heard this stuff is some of the best, and one of the tans professionals use. Should we have stopped part way the pickling step and fleshed the saddle from the muskrats after the hair was locked in? Did we over-work the hides breaking them, or start too early? As soon as the faces and edges started to stretch white, we started breaking them. As long as the hides started to feel a bit sticky to the touch and would stretch slightly white, we pulled a little and hung them back up. We kept at this all day, also rolling them over the sharp backside edge of the fleshing beam. This helped break up the saddle and turn the leather white. They just never got soft. Did we over-tan, and how would I know? I was confused about the formula. ½ gal water, 3 oz. salt and ½ oz. of EZ-100. is that oz. by weight or dry volume? I assumed dry volume for those and liquid volume for the acid and Ultra-Soft. After neutralizing we very thoroughly rinsed, and mixed the tan. We weighed 9lbs of wet drained hides => 4.5gallons water, about 4 cups of salt, and 1 1/8 cups of tan. Does that sound right for 13 rats and 2 coon? I read the package instructions and also Amy’s, but they were a little different, and ounces are different by volume and weight. After mixing the tan, the pH read 7.0 which was alarmingly high. I had already put my pickling acid away so I had to use more than a quart of white vinegar to bring it down before adding the hides. Thanks for the help. There’s a lot of knowledge out here that helped me get this far.
