"Mineral oil has issues too. I did a bit of research into mineral oil, not random people on the internet but actual research papers. Mineral oils are absorbed through your skin and can cause health issues. Unfortunately, most, if not all, of the information is behind a money wall where you have to pay to read the research. Mineral oil is a liquid byproduct of refining crude oil to make gasoline and other petroleum products."
Mineral oil is sold in most stores as a natural laxative. It is meant to be taken internally for it to work, although I've never tried using it that way...LOL.
It's also in cosmetics, baby oil, massage oil, that's all I'm going to tell about that use...LOL, and a host of other things in everyday life. Maybe there's an "industrial mineral oil" also that's not as refined ??? I'm not worried about the mineral oil itself, if I had to take a tablespoon of something in the shop I put on wood....that would be better than lacquer or shellac!
You can get a pint of mineral oil at Walmart for $1.98...at Home Depot Watco Danish Oil is $8.98. If you're doing one or two or a few it doesn't matter. When making a hundred to two hundred puzzles it does , at least to me.
