CRUCIBLE GLAZING

Instead of lining your clay crucible with asbestos, it is suggested that the crucible be glazed with borax.

• Heat the crucible in a burnout oven at 1100ºF for 10 minutes

• Place the hot crucible on a heat resistant surface

• Next take a torch and adjust the flame as if you were going to melt metal and heat the interior surfaces of the crucible until red hot

• Apply the borax

• Again torch the crucible as before until red hot

• All glazed areas will have a shiny appearance
