I use odorless turptine, Liquin, and a concocted mixture I put together famed by the old masters:
5 parts turp
1 part stand oil
1 part damar varnish
I'm interested in using clove oil as a medium, I've read the drying time is very slow on it but it has a nice aroma and it makes the paint very buttery so it glides
across the canvas. I've read that Malcolm T. Liepke uses it in his work.
