blood is used in some leather treatments?

[jouLe]

Hey all - I have been reading about the various uses for various by-products of beef (I recently butchered a steer and want to make the best possible use of everything) and I read that blood is used in some leather treatments. Is anyone familiar with this? Can you tell me more?

My method. I cut a piece of leather for a project and get it just the way I want. Then I usually manage to stick myself with the awl or nick myself with a blade, of course without noticing since I'm concentrating on something else. Then there are all of these little blood spots on the leather piece. Even though I do this quite regularly I really don't think this is the way you were talking about.

Keep on Smilin

Ha ha, good one Jim. Does it do the leather any good? I can't really find any more info on it - it seems to be an industrial process. Apparently blood is also used as glue for OSB and all sorts of other unimaginable things, so it could be just a factor of blood used in some commercial leather treatments. I will abandon this train unless someone comes up with something.

The key is to get your jugular. I can never get a whole piece dyed with pin pricks Seriously though, Blood is a biological material and I'd imagine that it could go rancid after a while. Might be an interesting experiment though.
