• Grey Agate is a natural type of quartz with high hardness and excellent resistance to abrasion and wear. • It is ideal for use in grinding and mixing due to its durability. • Agate Mortars and Pestles are used in labs to crush, grind, and mix chemicals. • The Mortar is a bowl-shaped container. • The Pestle is a heavy, club-shaped tool used to grind substances inside the Mortar.

• Black Agate is a natural form of quartz known for its high hardness and resistance to wear and abrasion. • Agate Mortars and Pestles are used to crush, grind, and mix chemicals. • The Mortar is a bowl-shaped container. • The Pestle is a heavy, club-shaped tool used to grind substances. • Materials are placed in the Mortar and crushed or mixed using the Pestle.

• Alumina Crucibles are made from high-purity aluminum oxide. • Alumina has high thermal conductivity, hardness, and heat resistance. • It is ideal for furnaces, thermocouples, and chemical processing equipment. • Also used in semiconductor parts, gas nozzles, and wear-resistant tools. • Can be joined with metals or ceramics using brazing techniques.
