Why the Rim and Base Are Unglazed
Glaze can soften at high temperature, so the surfaces that touch something else are left bare: the unglazed rims of the crucible and lid do not fuse together, and the bare outside bottom does not stick to a pipe-clay triangle or furnace floor.
Heating to Constant Mass
Heat the empty crucible and lid, let them cool in a desiccator and weigh them, repeating until two weighings agree. Add the sample, heat again with the lid slightly open so gases can escape, and cool and weigh as before. Move the hot crucible only with tongs and set it down on a dry surface, as a cold or damp one can crack hot porcelain.
