Today I finished filling in the small gaps in the blue sky background on this sun, which I decided to call “Fireball”. I didn’t glue the background glass in place (just the glass for the sun). That was foolish, but I did it because I was impatient and didn’t want to wait a few days before pouring the resin. If I glue the glass in place, I have to wait for it to completely cure / dry. The benefit is that there are a lot fewer bubbles when I pour the resin.
To get rid of the bubbles, I had to stand over the mosaic for a couple of hours and blow them with my heat gun. I ended up just running the heat gun over it every 5-10 minutes. Hopefully no more have popped up since I left it, but it seemed to be done with the bubble phase after about 1.5 hours. This is pretty long – it shouldn’t generally take that long to set, but I was very quick with the mixing today since I didn’t have any pigments, etc to mix in and I was only working on this one project. I used 16 ounces of resin and only had a very small residual amount left over.
