>Here is a shot of the 2 goblets inbedded in the castncraft. This project is finally coming together. This is only one part. The glaze around the goblets may be caused by using CA glue as a sealer. With the mirror coat I had hundreds of bubbles surrounding the goblets. Enough to almost completely obscure the goblets. Just for fun I'm going to make another one without putting anything on the goblets.

>Hi John,
If you continue to have problems with bubles, perhaps there is a way to accomplish the embedding under vaccum ? I used to work in a technical capacity where I had to embed various tissues in hard plastic resins. While in my case the big issue was getting all the water out, so the tissue could be infiltrated with the resins, air bubbles were sometimes a problem, too. We used a small vacuum oven to cure the plastic resin for this reason. Basically, in a low pressure environment, the bubbles become larger, so they can rise out of the liquid, and reach the surface. In a sense, you suck the resin into the wood, and suck the air out.

I've thought about vacuum for years and have a vacuum pump I use for the lathe. I'm currently looking for some sort of bell jar just for experimenting sake. I don't normally have much of a problem with bubbles but have never tried to imbed small wood inside the resin before. The heat from the reaction seems to be what's causing the problem. Compatibility of the sealer also seems to be a problem. I'll keep experimenting as time allows.
