Porcelain Crucible,Low Form with lid,Glazed

Low form crucibles are glazed inside and outside except for outside bottom, withstands temperatures to 1150 degree celsius, covers are included.

Crucibles and their lids are made of a ceramic that can withstand high temperatures. The crucible is used to heat chemicals (usually solids) to high temperatures. This may be necessary to dry a solid completely, or to initiate a reaction outside of solution.
