I use an electric griddle with heat control as a palette. You can mix encaustic paint right on the griddle or mix large quantities of paint in cat food cans. The paint is made by mixing some of the melted medium (damar resin and beeswax) and oil paint. Notice how a clothespin makes a heat proof handle for the tins. To clean the griddle, I use melted paraffin and wipe it with paper towels.
