GA-788 Glass Alchemy, Passion Extreme Glass Rods are sold per rod. Approx. 10 inches. 33 COE. Passion Extreme, 788 is designed to strike deep and dark in a thin application. This highly saturated sibling of Triple Passion is a must have! This rich color has a lot of potential for different finishes depending on whether you kiln strike and/or flame reduce. The base color is similar to GA Triple Passion, but moves into deep purples quickly. This color sometimes reminds me of a concord grape in the way that the light bursts and highlights of ghosty silver-blue appear over a deep warm purple. The purple will become darker and darker the longer it is worked and if your piece goes into the kiln and you still want a darker color, then strike at 1100 F for 15-20 minutes extra. You can always change the look of the top layer of Passion Extreme by blasting a sharp and hot flame onto the surface, immediately cutting through the silver build up and reversing the strike of the "skin" of the color. From there it's just in how you expose it to the flame or kiln that will determine the outcome of this wonderful color. Passion Extreme holds up well in blown and solid applications, and thin stringers hold color well. When sandwiched under clear more light blue fumey effects are showcased over the base color.
