Or sometimes you simply mess things up and wish to know what the crucible contains exactly. Like when you think you throwing in a pure metal, but actually it’s an oxide or whatever, and you mess up the ratio. Or when you do it intentionally, because NEI shows it converts to, let’s say, ½ of metal, but in fact it smelts to ½ plus 1/72 or else.
Speaking of crucibles, how can I extract liquid metal from a bath? Several times I manually stopped the burning box with the lever with no understanding why it pours my copper in the bath. A few minutes later I realized that it triggers the faucet. But why faucet doesn’t get activated when the thermometer passes signal through this noteblock to a piston beneath it. Anyway, is it possible to get my copper back? It can’t be cast into molds, and I guess I can’t pour it in a drum, lol.
