Original description:
Small mod meant to ease the pain of sand while processing the space type resources from Space Exploration. Mainly because the only use for sand is glass, but my glass smelting setups have onsite crushing and I can't be bothered to redo them. To ensure you can't get infinite stone from this, it costs more sand to make one stone than it takes to get sand in the first place. Not meant for widespread use, but if you find you want the same solution to the sand byproduct, go ahead. :)
