The Mettler crucible is so simple, I know how to use it

A Mettler crucible is a vessel or melting pot made of highly refractory materials such as clay, quartz, porcelain clay, or more difficult to melt metals. Mainly used for evaporation, concentration, or crystallization of solutions, and for burning solid substances.

Mettler crucible and its usage method:

When there are solids to be heated by high fire, a crucible must be used. When using a crucible, the crucible cover is usually placed diagonally on the crucible to prevent heated objects from jumping out and allow air to enter and exit freely for possible oxidation reactions. The crucible, due to its small bottom, usually needs to be placed on a mud triangle to be directly heated by fire. The crucible can be placed directly or diagonally on an iron tripod, and can be placed according to experimental needs. Do not immediately place the crucible on a cold metal tabletop after heating to prevent it from cracking due to rapid cooling. Do not immediately place it on a wooden desktop to avoid damaging it or causing a fire. The correct method is to leave it on the iron tripod for Free cooling, or put it on the asbestos net for slow cooling. Please use crucible tongs to take the crucible.

Main purpose:

(1) Evaporation, concentration, or crystallization of solutions

(2) Burning solid substances

Precautions for use:

(1) It can be heated directly, and can not be quenched after heating. Use crucible tongs to remove it

(2) Place the crucible on an iron tripod when heated

(3) Stir when evaporating; Steam dry with waste heat when almost dry

Crucibles can be divided into three categories: graphite crucibles, clay crucibles, and metal crucibles. Have you learned about crucibles through Kaizheng's sharing? Please follow our website for more information
