This is my first real try with oils ,other than to dry brush hilites. and attempts years ago when all of my faces turned to a muddy color, and they all looked like miners. Is there a way to speed the drying time of the oils when I get something I like to save it when I drag one of my fat fingers through it when working on another area.

I use a crock pot set at about 125-35 degrees F.
It also aids in removing some of the gloss from the oils.
