I just discovered some new information.......
Mineral oil never dries! Therefore you can not put another finish on top of it. It is good for cutting / cheese boards and other things used for food that won't have any other finish and it looks good on most woods but, if you think that you could put polyurethane or shellac on top for a harder or shinier finish, it won't work very well.
I did not know that as I've never tried anything like that but, I needed to give a "heads up" to all of you scrollers that like a gloss finish on your work.
