[[File:crucibleinuse.jpg|250px|thumb|The casting crucible in use with aluminium. The molten metal is being poured into a lost-PLA sand mold]] Our casting crucible can melt up to a maximum 2L2 litres of brass, bronze or aluminium which equates to about 15Kg of copper alloys or just under 5Kg of aluminium and pour it into a variety of molds to form cast metal objects. It's rated for a maximum temperature of 1100C which is sufficient for aluminium, brass, bronze, lead, zinc and thetin, but is not suitable for any type of steel, The high-temperature thermocouple from the [[tools/forge|Forge]] can be used to check what temperature it's operating at and make sure that it is not over-heated. Owing to the obvious safety needs when working with large ammounts of hot metal, this tool requires [[tools/castingcrucible/induction|induction]]. The crucible is normally kept in the main workshop, under the workbench on the west side of the the hackspace, and some of the sand and accessories are kept underneath the storage shelves in the lobby area. The casting tray is kept outside behind the rear fire escape door.
