CRUCIBLE TONGS

CRUCIBLE TONGS

• Sturdy crucible tongs for use in the science laboratory.
• Variants available are thickened steel (black) or stainless steel (bowed or straight).

(Wikipedia excerpt: .."...Crucibles are used in the laboratory to contain chemical compounds when they are heated to extremely high temperatures. Crucibles are available in several sizes and typically come with a correspondingly-sized lid.[20] When heated over a flame, the crucible is often held inside a pipeclay triangle which itself is held on top of a tripod.

Crucibles and their covers are made of heat-resistant materials, usually porcelain, alumina or an inert metal. One of the earliest uses of platinum was to make crucibles. Ceramics such as alumina, zirconia, and especially magnesia will tolerate the highest temperatures.[21] However, chemical reactions with the material in the crucible must be kept in mind; the emergence of melting point-lowering eutectic systems is an especially important consideration...")
