It is a water-based paint that yields a low-to-medium-hardness coating that is 97% Zirconium Oxide and 3% Aluminum Oxide after heating to above 600°C (1112°F).   Easy-to-use coating that can be used to 2000°C (3632°F).

How to color a mold

One half of this mold was painted with blue food color so that the Glass Release Spray or the ZYP Aerosol can be seen. You will be able to see how thick and where you are covering the mold. The blue color will burn away and the mold will be white again. Do not mix food color with the water-soluble Glass Release Spray. The food color contains propylene glycol which will change the consistency of the liquid, making the sprayer clog. Here is a video on how to spay the mold and use food color to help you judge how much and where you are spraying:

Glass Release Improvements

BN Glass Release has some new upgrades. A mixing ball has been added to re-suspend the liquid. Just shake until you hear the ball and there is no sediment. The sprayer is shipped separately with the capped bottle. Always save the cap to reuse. Clean the sprayer after use by placing it in a cup of water and pumping water through it until it is cleared of Glass Release. This takes a little more work than our aerosol, but can be shipped anywhere in the world at a lower cost.
