Certus Quartz Dust (Applied Energistics)

Certus Quartz Dust (previously Quartz Dust) is a material added by Applied Energistics. It can be obtained occasionally by mining Certus Quartz Ore. More can be obtained if your tool has the Fortune enchantment. It can be crafted into a Quartz Grind Stone and Quartz Fiber (prior to r10.a), smelted into Silicon, and compressed into Certus Quartz Crystal. In later versions, it's also a component in crafting Fluix Dust.

Recipe
Certus Quartz Dust can also be acquired by placing Certus Quartz Crystal or Ore in a crushing machine. Certus Quartz Crystal yields 4 and Certus Quartz Ore yields 10 dust.
