Stained glass mosaic coated with resin in a recycled window. Approximately 13.5″ x 30″

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.

So I spent a couple of days figuring out how to make the background, or sky, for this sun mosaic. I had planned on a completely different approach, but after looking at various types of glass, I decided that the background I had in mind was too “busy” for the glass I chose for this sun.

To help me make the decision, I set the whole window over large pieces of “sky” glass. I really had planned on making the background out of many, varied shades and types of blue glass, but ended up deciding that the iridized Spectrum (one of my standby favorites for lots of things) would be best against the multifaceted colors of the glass I used for the sun.

I spent today cutting the larger pieces for the sky / background. It will likely take a couple of days to fill in the smaller spaces between these.

It’s always fun to start a new project. It can be a challenge to decide what to do next when you’re looking at a plain window. I really like to do sun mosaics, and I have a neat piece of glass that just shouts “SUN!” to me, so a few days ago I measured the middle of the window and then figured out what size sun I thought would look good there. I cut the circle down with my manual glass cutter, then smoothed the edges with my saw and grinder and glued it in place. Today it was ready to be joined by some rays.

I free-form cut the longest rays that will go to the left or right of the ball with my manual glass cutter, then smoothed the shapes with my saw and grinder.

Once I had a few cut out, I set them in place around the ball of the sun. I’m not worried about the small gap between the ball and the rays because I plan to add a second layer of glass in a circle around the edge of the ball when I am further along with the base layer of glass.

I plan to add a lot more detail in the background, but for now I want to get the major focal points in place around the sun. I haven’t glued any of the rays in place yet, but the ball of the sun is glued down.

I think I might try to not use any more of the glass I used for the main sun / rays in the rest of the background. The decision I have to make now is whether the rest will be various shades of blue or if I will add more yellow / orange / red flame accents. Once I fill in the entire background with glass, I will coat it with resin to bring everything together. While I was working on this, I rough cut two additional circles and some extra main rays in case I decide to make some additional, similar projects from this sheet of glass. While working with the extras, I stacked them together and really liked the look of the rays overlapping. That might be the next version of this – layered rays. The pieces get heavy when I use a lot of layers, but it might be a fun experiment.
