A method of sealing a surface and structure of a refractory crucible with a ceramic, comprising the steps of: (a) heating a refractory crucible to a predetermined temperature; (b) applying a wetting agent to a surface of the crucible; (c) applying a ceramic slip along the inner surface of the crucible; (d) applying a vacuum to an outer surface of the crucible; (e) removing excess slip from the inner surface of the crucible; (f) heating the crucible to remove moisture therefrom; and (g) firing the crucible at a temperature between 1.300°C and about 1.700°C. |
