坩埚, 耐热容器
a heat-resistant container used for melting or heating substances to high temperatures
A crucible is a small, heat-resistant container used in laboratories for heating substances to very high temperatures. It is typically made of materials like ceramic, metal, or graphite, which can withstand extreme heat without breaking. Crucibles are often used for processes such as melting, boiling, or chemical reactions that require intense heat. They are commonly used in chemistry and metalworking to perform tests or to refine substances. The design of the crucible allows for easy handling while keeping the material inside safe during heating.
