This mod adds a bunch of new stones to the already existing Granite, Diorite and Andesite.
These new Stones are: Marble, Limestone, Basalt, Sandstone (smooth), Red Sandstone (smooth), Acherite and Terminochite. There is also a Polished Variant for Stone and End Stone and a Polished Variant and Brick Variant for Netherrack.
You craft the Polished Variants like in vanilla, using 4 of the base Block:
Note that the Base Block for the Sandstone Blocks is crafted like this:
The Brick Blocks are crafted like this, using 4 of the Polished Variant of the Block:
All of the new Stones, except for Acherite and Terminochite, spawn in the Overworld like the other Stones. Basalt spawns deep down in the World, Marble in the higher parts of the world and Limestone somewhere in between. Acherite spawns in the Nether, similarly to Magma. Acherite spawns in a different form than on the pictures, it spawns as “Blazing Acherite”. It is so hot, that if you step on it, you burn yourself. This can be avoided by sneaking. To transform Blazing Acherite into regular Acherite, you have to drop the Item into a block of Water.
Terminochite generates in the End, it is somewhat rare. When you break it, it has a chance of teleporting you around, which can be quite disorientating. It has a nice, deep purple color. There are also Slabs and Stairs for all the new Stones, but only for the Cobblestone (if available) and the Brick Variants. You can also get the Base Block by smelting the Cobblestone in a Furnace.
