  • Grooved graphite crucible : Grooved graphite crucible made of natural graphite with good thermal conductivity and high temperature resistance, and has a small thermal expansion coefficient during high temperature use. Specially designed for easy removal from the furnace say no to any metal waste.
  • Warm Tips: Pure graphite crucibles cannot be heated in coal or carbon furnaces. This jewelry making tools will rust and break; pure graphite will begin to oxidize at 752 °F (400 °C). If an air heater is used, the temperature can withstand temperatures up to 3200 °F.
  • Ingredient: This melted gold and silver scrap steel furnace with 99.9% graphite. The ash content is less than 0.1%. Excellent thermal conductivity and corrosion resistance. More suitable for refining graphite crucible made of silicon carbide.
  • Application: Our graphite crucible can melt alloys such as gold, silver, platinum and other precious metals, and has a long service life.Long Service Life -- The surface of the graphite crucible has a special glaze layer and dense molding material, which greatly improves the corrosion resistance of the product and extends its service life.This casting mold melting gold and silver graphite crucible has good thermal stability and is suitable for emergency or cold conditions.

I haven't had the chance to use this crucible yet, but based on feel and appearance it seems to be exactly what I'm looking for. Very nicely made of highly compressed carbon.

Disposable after about 5 hours in my experience, never came broken or even scratched!

This is a bad crucible. Mine got a hole in it while melting copper and poured all of the molten contents inside of my furnace. Don’t but this
