Made from high-purity, high-density graphite, this crucible offers exceptional thermal stability and can withstand temperatures over 2000°C. 

It heats quickly and evenly, reducing melting time and saving energy. With strong resistance to heat shock, corrosion, and abrasion, it lasts 

more than twice as long as ordinary crucibles. Its low ash content (<300ppm) keeps precious metals pure during melting. Ideal for jewelry, 

casting, and metal refining.
