UGC Bubble Paint
The UGC Artisan Colors bubble paint is non-toxic, lead free and comes in powder form. Works great when mixed with UGC Medium. We currently have 15 colors available. These colors are transparent/translucent and bubble when kiln fired between layers of glass and are textured, opaque and glossy when fired on the top layer of glass. By using specific placement techniques, you can actually control your bubbles!
It is recommended to vent the kiln during the initial stage of the firing process. (Firing range is 1425F to 1550F on float glass.)
