I am getting into preserving old skills, crafts, tools and also products. So far the introduction.
Here's the deal:
My dad has a small tin that was passed down all the way from my great-great grandfather and his family, who owned a self-sufficient farm at the time that was still possible in The Netherlands.
In the tin is a wax-like, fatty, dark yellow (almost brown) substance with a rather interesting smell, unlike anything I've smelled before. All the generations who owned this tin used it to maintian leather, something
it does extraordinarily well. My dad once told me it was made with lots of stuff, including pig lard and human urine, but he's not sure.
My question now is: Does anybody here at permies recognise, or even have experience or knowledge with using this mysterious substance? I would like to set up a recipe so I can re-make it, because the tin is finally running out. It would be an absolute shame if the recipe were to be lost. I have never had better leather care products.
Your knowledge and experience is well needed and appreciated,
