How to use Reversible Molds:

Kiln Wash.
To prevent glass from sticking to the steel mold you should coat it with either kiln wash or spray on mold release.  If you use kiln wash, sandblasting or hand sanding the metal first to scratch it will help provide “tooth” for the kiln wash to stick to the metal.   Paint on at least 3 coats to ensure even coating.   A good “trick” to get a good kiln wash coating is to place the mold on your kiln while it’s firing.   When the steel mold is heated, the kiln wash dries quickly.   Use a piece of tin foil or a cookie tray beneath the mold to catch drips.

Boron Nitride

Spray on boron nitride will provide the smoothest finish and can be applied without pre-sanding the metal.  Spray on from about 12 inches away in smooth even strokes.  Avoid getting it on too thick.   Several thin coats will ensure the smoothest finish.   Trying to apply it too heavy or too thick will cause it to run and leave waves that will show in the glass.  Fumes from boron nitride are nasty.  It’s a good idea to spray outside or wear a respirator when spraying.   Maybe both.  Once you have a good coat on the mold, handle it carefully to avoid scratching or smudging the coating.   You can fire it a dozen or more times without recoating if you don’t disturb the boron nitride.  If the coating starts to break down, just gently wipe if off with a soft cloth and spray on another coat.
