Firing Temperature—1250-1450 F
Mixing: All Reusche colors come in a powder form and need to me mixed with a vehicle before application.
Each kit includes Gum Arabic, and two different types of mixing mediums.
Mixing with Gum Arabic: Start with the color. Place a small amount onto a ground glass slab and flatten the color to approximately 1/8” thick. Sprinkle the Gum Arabic over the color, just enough to look like freshly fallen snow. You should be able to see color underneath. Add water in small amounts mixing between additions. You want a consistency similar to yogurt. The paint should be soft but retain its shape. It the color spreads out on your slab, it is too thin. More color can be added to the mixture to thicken.
Mixing with oil based or water based medium: The recommended ratio for mixing with most mediums for hand painting is 80 % color by weight to 20 % medium by weight. Weight your color, add your medium and mix to a smooth consistency similar to yogurt.
There are many different oils and mediums that can be used for mixing your color. Refer to the book “The Art of Painting on Glass” by Albinas Elskus for more helpful information on different mixing mediums and techniques.
