Avid Uncrafting

This mod adds crafting recipes for the crafting table:

• amethyst block → 4x amethyst shard

  

• quartz block → 4x quartz

  

Why do this?

I, personally, was annoyed that I could not craft amethyst blocks and quartz blocks back into their respective components like I could with several other items in Minecraft (e.g.: diamond, lapis lazuli, iron).
