Morning folks, I have a question regarding finishing alum tawed leather. Up until now I have worked solely with veg tan and a little bit chrome lamb nappa.
I have received a sample from a tannery of some very nice soft pure white goat skin which I would love to use and have a couple of ideas in mind for, however it's alum tawed.
From what I have researched I know that water can have a big impact on it, potentially even sweat, by washing out the alum salts. Although what I'm thinking of should never normally get wet it may come in contact with sweat, possibly a lot depending on various factors.
My current finishes and conditioners are based round my veg tan work and I can't find much information on how to finish and condition alum. Most information on the web is about conservation of an old article for preservation rather than for use.
What can I use to give it a bit more resistance to water/sweat which will give (hopefully) no change to the whiteness but if that's not realistic then minimal change.
Thanks very much
Stuart
