Diamond Glass is a mod that aims to allow us to create crystals and building blocks capable of resisting even explosions, as if they were obsidian blocks, although this functionality is not cheap, since we will have need diamonds to create these blocks and crystals.
With this mod installed we can make blast resistant glass blocks and glass panels. We will also be able to create explosion-resistant building blocks, stairs and slabs, which will allow us to have an alternative to obsidian.
This new material, called Diamond Glass, is the result of the combination of sand and diamonds. Since it is a very hard material, it will also be difficult to remove the blocks once they are placed.
