Yeah, just a small thing, I don't know if you've ever noticed that glass is literally the same thing as fused quartz. I just thought a slight name change might make it a bit more realistic. Something along the lines of Hard Glass or something idk, just a suggestion.

Naming it Hard Glass would make it almost equal in names to TE's Hardened Glass which could be confusing.

Maybe it should have been named "Fused Nether Quartz", but (in Minecraft chemistry) it certainly isn't made from the same thing that sand is made of.

I think Bonded Quartz would work, or maybe Synthesized :P
