CRUCIBLE: Nickel, 25ml

•  A 25ml Nickel Crucible required for the NCEA experiment where they are heated on a hot plate.
(Note: *Ceramic top hot plates don't have an even temperature across surface area which can differ results when a number of crucibles are being heated at same time.)

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

[C] 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 [C] . Ceramics such as alumina, zirconia, and especially magnesia will tolerate the highest temperatures.[21] However, chemical reactions with the material in the [C] must be kept in mind; the emergence of melting point-lowering eutectic systems is an especially important consideration...")
