This fabric Minecraft mod makes you able to smelt sand to glass in a blast furnace, which means you can smelt sand at 2x speed.
Blast furnaces are in real-world used to melt sand into glass so it would make sense if it was the same in Minecraft.
If you like this mod then you might also enjoy Craft Better. It's a mod with more small crafting tweaks just like this one.
