Can I use normal oil for oil painting?
It is possible to use any vegetable oil for painting, even those that do not dry can be fused with pulverized lead and then cooked for a long time to make them more pliable. It is best to stick with Linseed, Stand, and Walnut oil, these are the ones that have been around for a long time.3 Dec 2021
