Pure Quartz

Pure quartz was added so you can still get silicon, but not also be able to obtain the nether quartz. It's texture is of nether quartz, but with a cyan tint to it.

Trivia

 * Before, you got nether quartz with smelting 2 sand, and you used the nether quartz in the cutter to get the silicon.
 * This replaced the use of nether quartz in the recipes because MCE thought it was a way too easy way to get nether quartz. So he added this in, which can't be used in nether quartz recipes.
