Melting bronze, copper or red brass requires a silicon carbide crucible, cast iron requires a clay graphite crucible.
1.Lift crucible with tongs. 2.Place in pouring pigtail. 3. Pour metal into mold.
Pictured in the photo below are 2 types of lifting tongs for silicon and clay crucibles, the one with handles sticking out requires two people, the other requires one person. In the center is the pouring shank required for this type of crucible. You can get this at Mifco.com.
To clean a silicone carbide or clay graphite crucible they must be carefully scraped with a steel half moon shape that contours with the crucible while still hot.
*Steel crucibles are not recommended for melting bronze, silver, gold, iron, steel, titanium or others. See above. During melting some iron contamination will occur, unless a ceramic coating is applied. Most aluminum and brass casting alloys have some iron already in it, not really a problem in most cases.
