Okay, so I have installed TerraFirmaCraft yesterday, and I have been trying to work with metals.
First of all, I get everything ready. Then, with the bloomery, I make some tin in a ceramic mold.
Then, I read on the wiki that it needs to be cooled to the brilliant white stage.
So, I figured that the metal needed to be out of the liquid stage, and in the solid stage.
After it is nearly out of the liquid stage, I got bored and left it on the anvil to go screw around with other items.
I come back to find that the metal disappeared straight out of it's container.
What am I doing wrong?
