This furnace can reach as high a temperature as 1450°C, hot enough to melt aluminium, brass, copper, silver and cast iron. | This furnace can reach as high a temperature as 1450°C, hot enough to melt aluminium, brass, copper, silver and cast iron. It acts as the heavier-duty companion to the tabletop [[Casting Furnace (Vevor M.MF.02000)|electric furnace]]. | ||
To summarise the process of using it (full details will be given in training) - a crucible full of metal is lowered into the chamber and the gas ignited. By careful management of the air-fuel mixture the metal is bought up to melting temperature. Once liquid, the gas supply is shut off, lid opened, and the crucible lifted out and placed on an insulated surface. A teaspoon so of flux is added to bring out impurities which are then scraped off with a drossing spoon. The liquid metal is then poured into the appropriate mould. | To summarise the process of using it (full details will be given in training) - a crucible full of metal is lowered into the chamber and the gas ignited.
