This is kind of a joke mod. But yeah, the title says it all: It adds things from glass.
It adds a sword, which is VERY poweful, but breaks quite quickly.
It also adds a gun, which is also quite powerful, but breaks quickly, too.
There is also a toolset. They are all very efficient tools. However, they break quickly. There is also a multi-tool, which doesn't run out as quickly, and acts the same as the pick, axe, and shovel.
I got the idea of making this mod because of how tedious it is to get to the nether, which requires obsidian, which requires a DIAMOND PICK. So I made this mod for to get to the Nether early-game.
