While working (hand stretching, breaking with ulu) the deer hide in my house last evening, I noticed more hair than usual had “shed”. Then I realized it wasn’t the usual, minimal shedding that deer hides do – it was slip.
Hair slip or slippage is what we call the hair/fur/wool falling out of a hide when we don’t want it to. It’s a result of bacterial activity & decay in the epidermis, and means that the hide is not properly preserved or tanned yet.
In this case, my mistake has been keeping the hide in my warm home while also trying to dry it slowly. The hair is slipping a bit where the skin is still not dry – where it’s also the thickest – between the shoulders.
To try to keep the hide from drying too quickly between stretching sessions I’ve been rolling it up. Probably a fine idea at 45 or even 50*, but we’ve managed 67* in my home recently and that’s too warm to be mixing with damp.
The hair loss is not visible – yet. I hope it won’t be. As soon as I realized what was happening, I moved the hide back out to the extremely cold garage (it went down to single digits last night) and laid it out flat.
I also poured some alum on the center part, on the skin side where it isn’t dry. Tawing with alum is a step I usually include automatically in my tanning, but didn’t with this skin for 2 reasons: I taw in an alum pickle which would have meant submerging the hide in water when it was too cold for water to remain liquid, and because I thought I’d be processing the hide fast enough to not worry about slip.
So. I think the dry alum will prevent any further hair slip. I’d rather have a hide stiffer than usual than with bald patches. And I’d like to get this guy smoked in the next couple days. However, it’s 8* with negative 20 windchill out there right now. No smoking today!
The goal now is to smoke him on Wednesday or Thursday, which is 2 or 3 days from now, if the forecast for highs in the upper 20s/30s holds true.
Learn learn learn! It’s what I do. It’s what this process is. Every hide is truly different. The environment you tan hides in, like a river, is never now as it was before.
