800 Degree Glazed Engineered Ceramics Crucibles , Zirconia Crucible With Cover Lid

                 Glazed Porcelain Crucible with Cover Lid

      Place the crucible on a burner. Heat the crucible until the fused bicarbonate melts. Heat it until a layer of red potassium salt appears on the surface. Using a mixing rod, stir the melt a few times. The entire melting procedure should take about one minute.
     Remove your crucible from the flame. Pour out the melt. If your crucible is made of porcelain, continue to step 5. If your crucible is platinum, submerge it in a boiling glass bath of hydrochloric acid (a 20% mix to water) for three minutes.
     Rinse the crucible in hot water. For porcelain crucibles, use a clean cloth to dry the surface. If your crucible is platinum, use alumina-impregnated nylon webbing to complete cleaning the surface. Let the crucible cool.
