Just finished the pine coat but added a pinch of wax to prevent the the paint from cracking. Read an article about tempera and the transition to oil. The idea was to mix egg, oil, wax, pigment, water and dryer. The wax prevented cracking and the oil helped spread the paint. I am going to mix egg, pine, wax, alcohol, and pigment. This should make an interesting paint
Below is pigment scrapped from a rock I cooked. The pictures should tell the story. Clean up was hard so rubber gloves and paint outdoors.
