Coralium Stone is a recent addition to AbyssalCraft. It is created by the Player.
How to CreateEdit
Creating the Coralium Stone is a simple process. It requires the Player to collect Anti-Matter, then to dump it over Liquid Coralium. Once this is done it will create Coralium Stone, similar to how Lava and Water create Obsidian.
Coralium Brick is created by putting Coralium Cobblestone inside a furnace, then putting the Coralium Stone into the furnace again. This will create Coralium Bricks.
