There are mods you can get that allow you to build with glass constructs. My server actually uses them both, since each one comes with different benefits.
Great mod, gives all sorts of higher level weapons/armors, building materials, and lots of stuff to role-play with if you’re into that, or just stuff to have fun with if you love building. One of the extras it brings are glass constructs, which my wife used to make a gigantic glass tower/obstacle course. She has spiral stairs, wall puzzles(some of them glitched so bad that you have to climb the walls in weird places to continue going up, it was a beneficial error, so to speak lol), glass maze, and tiny ninja-warrior obstacle course all along the way to the top.
That’s the one you linked, and it has a lot of nice constructs in it as well. My wife preferred to build with the AoC glass, since it was cheaper to build, but the glass from here connects better with less glitches. They also give you “Greater” stations, such as a “Greater Furnace”, which is a huge furnace that holds a LOT of stuff in it. My base used to have 12 imp. furnaces to ensure I could be efficiency, but thanks to the greater furnace I only have 1 greater and 4 imp. furnaces. The only reason I kept the imp. ones is just in case I needed something specific to smelt, all the while still being able to smelt large amounts alongside it.
So if you don’t mind playing with mods, the glass stuff is a blast to build with.
I’ve never heard of glass constructs ever planned to be in the game, so I’m not sure there. I always just assumed these were really nice mods.
