Smooth Stone is unable to be smelted in the Furnace which makes it impossible to craft the Blast Furnace. So I checked the Stone cutter to see if it could be crafted, but when you put stone in the Stone Cutter you can craft everything from a Stone including Granite, Diorite, Stone Brick, and Andesite. All the Stairs, Slabs, and Blocks from one Stone except no Smooth Stone products. Clearly the Smooth Stone and Stone Cutter are Broken and the Blast Furnace is un-craftable but still found in villages.
