Stone and Cobblestone
The new rock types can be used in the place of stone and cobblestone in vanilla Minecraft recipes.
If you need cobblestone, use this recipe (or you could make a cobblestone generator using lava and water):
craft 2 gravel blocks + 2 rock blocks = 4 cobblestone blocks
You can now smelt gravel directly into “stone” blocks.
Stairs and Half-Slabs
All rock types that have polished versions can be crafted into stairs and slabs (the polished blocks can also be made into stairs). Stacking polished slabs on top of each other makes for nice stone columns.
These panels are crafted from gypsum and paper and can be colored like wool.
1 Saltpeter + 1 Sulphur + 1 Charcoal = 4 Gun Powder
1 Saltpeter + 1 Sulphur + 1 Sugar = 4 Gun Powder
Mineral fertilizer is even better than bonemeal for growing crops because a single use fertilizes a 3×3 area.
1 Saltpeter + 1 Phosphorous = 1 Mineral Fertilizer
