To provide minimum oxidation in the casting of gold alloys, it is recommended that a thin film of borax be melted into the discharge path of an orifice prior to making the first melt in the crucible.

Using Ceramic Crucibles
Clay crucibles need to be treated before use for extended life. Fill about 25% of the crucible with a mix of 50% borax* and boric acid*. Heat the crucible gradually until the mixture melts. Carefully tilt the crucible so as to coat the entire inner surface. Then pour the excess away and allow the crucible to cool to room temperature. * See Page # 273
