Rock (GregTech 6)

The rock is a block and item added by GregTech 6. It can be mined with a pick to apply fortune, or simply right-clicked to be harvested. It ignores Silk Touch, and cannot be gained as an item. The block texture will change to match the supporting block if it is Mud or any type of Stone. The rock is a non-ticking tile entity that contains only the material id byte specifying what will be gained by harvesting it.

Rocks that become Meteorites, Stone Rocks, or pieces of Flint when harvested all generate on the land surface. The variety of stone is determined by the Stone Layer Generator for the rock's position, it will generally be the same as the rock to be found just below the soil. Rocks that will be Ore bearing Rocks when harvested spawn in air at the same X and Z coordinates of an ore block generated either as part of the Stone Layer or by a major vein, this can be in a cave or on the surface.

The material is specified by the metadata for the item. The item name is localized as one of: 'meteorite' for Meteoric Iron, '[stone] rock' for any stone type, and '[ore] bearing rock' for all other materials; these three categories also have different sprites for the item.

Usage
Stone Rocks take the place of both ingots and plates in the crafting recipes for Meta-Tools made of that material.

Meteorite and a select few Ore bearing Rocks can be used to make Flint and Tinder.

Any Rock can be decomposed (by Mortar, Shredder, Extruder, Smelter, or Smelting Crucible) into 0.25 Units of its material.
