The Crucible Faucet is a tile entity added by GregTech 6. It is used to output molten material from the Smelting Crucible. It will pour any distance down into a Mold, Basin, Mixing Bowl, Bathing Pot, or Smelting Crucible that can handle the molten liquid, even through other Faucets and Taps. The Faucet must also be resistant to the material being poured.
A rising redstone edge can automate pouring from a Faucet.
