Graphite is a stable and reliable material with excellent strength at low and high temperatures. The thermal shock resistance eliminates spalling.
This crucible contains fixed carbon which gives a good thermal conductivity and thus reduces melting time, saving you both time and money. As the raw materials used are strictly controlled, impurity inclusion risk is eliminated. This graphite crucible has an ash residue rate of less than 0.1% ensuring that the metal is not contaminated during smelting.
Graphite crucibles can leave a residue on fingers, gloves or cloth. Clean carefully after each use as graphite can be hard to clean. Crucibles can crack or break if dropped or knocked. Ensure all appropriate safety.
