Changes:
- 4x increase in density of molten metals.
- Add 2 cryonite slush to casting recipes to decrease their crafting times by 5x.
- Cryo cooled ingots also provide 10% more yield to make up for the increased cost and complexity of using cryonite slush.
- Moves anything in "kiln" crafting category into "smelting" category. (this puts bricks back into the industrial furnace)
- Compatible with Krastorio 2 and Brevven's mods.

I'll fix the funky side pipe graphics when Earendel finishes the casting machine graphics.
