Black Quartz

Black Quartz is a mineral in SevTech that is found in the Beneath dimension as Black Quartz Ore, accessed by using the Beneath Teleporter, and is present from the y-levels between y=0 to y=150 [correct if range is wrong]. It is processed by crushing the raw ore (with a Grindstone or other crushing device) and can be used as dust or smelted into the mineral. Multiple crafting recipes, such as Axles and black iron, utilize black quartz in their crafting processes.
