A Nanonite is a compressed solid form of lava, combined with water to much more solidify the lava, and diamonds to purify the new obsidian. It is afterwards heated into acid and cooled up in water. After all these processes, the obsidian becomes diamond-like glass containing cyan bubbling water, then the glass gets the effect of the water, the color of the water, then the water solidifies, forming the new Nanonite.
Nanonite is very rare underground. It can be used to craft 9755-durability armor, 8990-durability tools, and Nanonite Blocks, which look like deep-purple emerald blocks with a touch of the gold or diamond block texture and the iron block texture.
