We poured metal on Friday and anxiously awaited Saturday when we could bust open the mold and see what we got. We had no clue what to expect. Since it was such a large mold, we could only keep our fingers crossed that we wouldn't run out of aluminum... the biggest crucible can only hold 80 pounds! There were fears of air bubbles, leaks, and shrinkage, all of which occurred, but only on a minimal scale. We're hoping it's nothing we can't fix.
