I know this will likely be a very niche question, but I'm going to ask it anyway because in my quick searches I haven't found any answers.
We all know the dangers of soaked boiled linseed oil rags, so the advice given today is to lay it flat, let it dry, and throw it away, and/or burn it. But this seems only "appropriate" when rags are cheap, as in our disposable society. When things were not so cheap, so, during the time of woodworking shops in the 17th-19th centuries, what did people do? Did they have a different way of reusing rags? Or did they have a "cheap" source of rags as well, as maybe from nearby fabric or paper mills?
Maybe I'll have to dig into the primary literature of the time to find my answer.
