A crucible is a container for molten metal. Heated in a furnace, then removed to pour into molds.
1.(far right) Silicon carbide. Melts bronze, brass, aluminum, and lead.
2.(center) 10 gauge steel. Melts aluminum, brass and lead.
3.(left) Coffee can, aluminum and lead only. Caution Dangerous!
Silicon carbide crucible requires a lifting tool and a pouring shank.
A steel crucible is poured by one person with the small rectangle wire to lift the crucible. A coffee can can be lifted with a coat hanger (wire).
These are two very used crucibles. On the left is a silicon carbide crucible, on the right is a clay graphite crucible.
This is a bottom pouring crucible.
A spout goes to the bottom to continuously skim the metal during pouring.
After a used crucible gets about 1/2 to 5/8 inch thick, it is discarded.
