Product Description

 

Product Description

 

A ceramic crucible is a heat - resistant container. It's usually made from materials like clay, porcelain, or other ceramic substances.
 
These crucibles can withstand high temperatures, which makes them ideal for use in processes such as melting metals, conducting chemical reactions that require heating, and in laboratory experiments such as sample preparation for analysis. They are chemically stable to a certain extent and help to contain substances during heating without reacting with them easily.
