Graphite lined Gold and Silver Casting Crucible for EC-12
This crucible is for the Ultraflex EC-12 Casting machine. It comes with a lid that is held down by the spring clip on the EC-12 swing arm and keeps the crucible in place. It has a nose to help align with the flask pour basin (button). The capacity of this crucible is about 150 grams if you are using small pre-shot material. Pre-melting in order to attain higher crucible weights is not recommended for Zinc containing alloys. I don't do it for any alloys in the EC-12 because of the straight arm of the casting machine.
