-Alumina crucibles (or corundum crucibles, aluminum oxide >99%) feature highly resistant to chemical erosion. This material has the characteristics of high hardness, high-temperature, and corrosion resistance. It comes with a cover for easy handling

-Recommended for chemists, furnaces workers and others involved in high-temperature work-free results. Widely used in melting gold, silver, copper, aluminum, tin, lead and other metals; melting aluminum cans, cans; scrap metal recycling; casting silver, silver balls, knives.

-For use in reducing and oxidizing atmospheres and refractory metals (such as molybdenum, platinum, rhodium, tungsten, tantalum).

-Heating or cold too fast or uneven heating may crack the crucibles. Slow down the heating / cold rate is good for extending its lifespan. Do not get wet, store in a dry place. Once the crucible is dry, do not expose it to water.
