99% Pure Nickel. Remaining 1% is made up of trace alloys including copper.
41mm high x 36 mm top diam. x 26mm bottom diam.
The melting point for a nickel crucible is around 700 deg C. Temperatures above this will result in the crucible oxidizing.
A Nickel crucible is suitable to melt the following: Sodium hydroxide, Sodium carbonate, Sodium hydrogen carbonate
A Nickel crucible is not suitable to melt the following: Potassium sulphate, Sodium hydrogen sulphate, Potassium bisulfate, Pyrosulfates, Borax (Sodium tetraborate decahydrate)
The following metals should not be used with/in nickel crucibles as they cause oxidation and damage: Aluminum, Zinc, Lead, Tin, Mercury
