Clear Coat Overglaze
Gives kiln-fired glass a durable, glossy surface. Lead-free and safe for food bearing applications. Great for all glasses, but especially preferred for Semi Antique and Window Glass. Easy to use. Prevents devitrification.
Using a soft brush or sprayer, apply a light coating to the surface of a piece of clean glass. Allow to dry, then fire to 732 degrees celcius (1350 degrees Fahrenheit) or above. Shake well before using.
