I am preparing to fill a void in wood using epoxy where a branch had died and surrounding wood had grown over. Researching on the web I learned that air trapped in the wood can rise through the epoxy forming bubbles. To solve this problem I've used polyurethane to seal the inside surfaces of the void, and after the polyurethane has had a few days to dry fully, I can begin adding the epoxy 3 ounces or so at a time, gradually filling the void level to the surface of the surrounding wood. It's experimental. My fingers are crossed.
I have been waking up in the middle of the night wondering how to solve this problem. My next question has to do with whether or not to add objects to the void or leave it so that you can peer clearly into the depths. No, I will not put LED lighting inside. Some craftsmen might be inclined to add colorants or powdered turquoise. I prefer a more natural look and the opportunity to look within.
Tomorrow I start my Jewelry Box class at the Eureka Springs School of the Arts.
Make, fix, grow and create. Our culture depend upon it.
