Mold (GregTech 5)

Molds are items used in the Alloy Smelter and Fluid Solidifier to determine their output. Like Extruder Shapes and Integrated Circuits, Molds are not consumed in recipes, and while some Alloy Smelter recipes can be carried out without them, all Fluid Solidifier recipes require them.

Crafting
Molds are crafted with an Empty Shape Plate and a Hammer. The locations within the crafting grid of the Shape Plate and the Hammer determine what shape of Mold will be crafted.
