During your study Conan Exiles, eventually you will stumble upon glass, and you might even want to learn how to craft it yourself.
First, you need a Crystal. It can be found in caves, or it can be collected from the corpse of Rocknose, which looks like a stone rhinoceros. Kill one of them and then use the pickaxe.
After that, you will need an oven. It can be opened according to one of your recipes using 540 stones. After building the furnace, place the crystal inside along with the fuel - coal or wood. To create one glass, you must use two crystals.
It is not yet clear what this resource is for in the game. Most likely, in the future, glass will be an important element for crafting, but right now, it is not used in any way.
