How To Use: You must prep them by melting a layer of borax into the crucible. Heat the crucible and shake a good teaspoon amount of borax into the crucible. As you melt metal into the crucible, the borax will keep spreading, filling and "glazing" it each time. After 3-5 times of melting metal, the crucible will be as good as it gets.
