I recently started trying something a little bit different with the backgrounds of my painted glass tiles. My normal process is to used glass frit (crushed glass) as the backgrounds behind my paintings.
I drew a picture of a little scene recently and drew in these layers of sky. The process of applying the frit is not terribly precise, but in my mind I could see very precise, colorful sections of sky working in this piece. So, I decided to paint it as I saw it and this is what I got:
Coloring the pieces this way is a little bit more time consuming and uses a little more paint. But, as you can see, the effect is stunning. I don't think it works for all pieces (maybe it would) but I definitely know that I will be doing it alot more in the near future.
Here are a few more pieces with the painted backgrounds:
