One of Fusion Master’s signature products….
At last, there is a very low-lead overglaze that prevents devitrification on kiln fired glass projects that is proven safe for food bearing surfaces. Super Spray will not discolor reds, oranges or other sensitive tones. For easy application, simply brush it onto your glass project or spray it on with an air brush or atomizer BEFORE THE FIRST FIRING. Matures at 1350F or higher. Super Spray is not designed to FIX existing devitrification.

What is glass devitrification? Glass devitrification is the process by which molten glass is cooled too slowly and thereby becomes crystalline, with a milky appearance, and no longer able to be used as glass.

Use Super Spray to hold mica to the surface of your glass. See what Dana Worley is doing…


– They all work
really well and there isn’t a bad choice.
Super Spray is a clear glass in powdered form, Clear Coat and Fusing Solution contain a boric acid flux that mixes with the surface of the
glass to prevent devitrification.

Super Spray is the
popular for colored glass, Clear Coat is used a lot by production houses working with float or
window glass. Fusing Solution is also a gel glue and it great when working with
frit, stringers, pieces of glass and dimension objects like bottles.

Bending Glass is for low
temperature work.
