Jlie application of aluminium and its alloys to industrialpur[)()ses has extended so considerably in recent years thatthe subject of their melting is bound to appeal to a largenumber of manufacturers. Generally, the melting of thesemetals has been effected in open crucibles, which allowatmospheric oxygen to attack the molten metal with theconsequent formation of dross. Other drawbacks to meltingaluminium in this manner are well known to those familiarwith the subject.
