New Artisan Color. This is Cornflower Artisan 619 paint for glass. This paint must be kiln fired. Cornflower is a bright cheerful blue. the second swatch show the sample back lit. This color line was first added by Unique Glass Colors in 2010 & more colors have been added since then. There are now 20 colors in the Artisan line. The colors come in powder form & are mixed with our UGC Medium to for a liquid. The colors are translucent/transparent & create bubbles when fired between layers of glass. They can also be used in their dry form & the bubbles will be smaller & darker between glass & they can also be use on the top of the glass for a darker, textured effect. By using specific placement techniques, the bubbles can actually be controlled. Artisan colors are designed to be fired between layers of glass. Mix with Medium on a 1:1 ratio for the look on the color chip photo that shows product fused on top of glass & fused in between layers of glass. The solid square is on the top piece of glass & produces a semi-transparent color that is mottled, slightly textured & the color fires a bit darker with no bubbles. The random bubble area of the chip is between the layers of glass & shows the color applied solidly then fused. The lined areas show the product applied in between layers with a 10/0 liner brush & if the lines are not allowed to touch during application you can control where the bubbles will appear. Applying the product heavier or thinner will give you different results. Cornflower Ugc Artisan Color 619, 1 Ounce Jar, Must Be Kiln Fired, Makes Bubbles New Color
