Playing around with with Minechem I finally found a use for those granite and diorite blocks in my storage system.
With Minechem, they can be turned into nether quartz!
The process is quite easy as each granite or diorite block will give you the components you need for nether quartz. Simply decompose the block into Silicon Dioxide and Gallium Arsenideand reassemble it in the synthesizer. One granite gives you one nether quartz.All you need is a little power.
Sometimes you will get a few extra elements such as magnesium.
