I'm guessing its clay powder and color. I don't think anything else is
in it. The only other thing that might be in there would be tapioca
flour. And oil/wax combo was put on top.

I have 1 gallon containers of linseed oil. I don't think it has any
chemicals in it for drying. I already put one coat of this oil on the
surface and it didn't do anything. Its as dry and dusty as it was before!

It's getting hot now. Getting to be summer. I'll try and see if I can
find Tung oil. As far as the surface coloring is now, its not that good either.
So some darkening wouldn't matter.
