As you know kiln wash is used to prevent glass from sticking to the kiln shelf or mold. This is a good thing because you never want to hack away at your kiln shelf to get your glass out of the kiln. That being said how do you make kiln wash?

First go to a pottery supplier either online or *gasp* in real life and buy some kaolin and alumina hydrate. Make sure you wash your hands immediately after using. Now before mixing make sure you are wearing a respirator and gloves. Next mix the kaolin and alumina hydrate together and then add four to six parts water until you reach the desired consistency. All you have to do now is either brush or spray lightly on your kiln shelf or mold. Lastly it is very important that you allow the kiln wash to dry thoroughly before firing.
