BubbleART is a fired glass color that is a non-leaded color and comes in 1-ounce jars. These 16 colors are translucent/transparent colors that were designed to be fused between two layers of glass to create bubbles. These colors are design dependent, meaning that where you put your design you can control the bubbles. If you use a liner brush and place lines on the glass and leave spaces between them you will get lines of bubbles. Solid areas will be all over bubbles. You can place dots of color and these will be small collections of bubbles.
BubbleART can also be used on top of the glass. You will get a textured look and feel. Some colors will be transparent and others will be opaque when used on top of the glass. Some of these effects are technique dependent. Mix 1 to 1 with GM300 Glass Medium. You can add more GM300 Glass Medium to change the consistency and your application which can change the color intensity.
Shake jar before mixing powdered colors with glass medium. These colors are much more gritty than the original glass color line. The gritty stuff will create intense color if you dont want that you can pick it off the wet color before it dries.
The heavier the color is put on the darker it will be. The thinner it is put on the lighter in color it will be. When using float glass (window) you tend to get larger bubbles. When using 90 or 96 COE you will get smaller bubbles. The float glass can be fired between 1425-1550 F. The 96 COE glass when fired to 1485 F tends to shrink in but the bubbles are a little larger than a firing of 1450 F with a 2-minute hold.
96 COE glass fired to 1390-1450 F is a nice fuse of the 2 pieces of glass.
The hotter these are fired the larger the bubbles are. Each kiln is different and testing should be done before starting a large project.
These above are done by brushing GM-300 Glass Medium on the bottom piece of glass and then with palette knife sprinkle on some of the dry powdered BubbleART colors here and there. Cap with another piece of glass. These are 96 COE, clear on clear and clear on a white background and clear on clear, fired to 1450 F with a 2-minute hold.
