Yes, really. These are painted with beeswax.
I love the smell of beeswax, the way it curls when you carve in it, and the way it is just plain defiant. I also love beach/sea glass. I have jars and jars of it from all over the world and sometimes a special piece finds its way into my paintings. So from time to time, you may see these two materials collide. I love the way the soft beeswax mixes with the hard glass - the contrast reminds me of myself.
