So ok first so firat sense its the same block Im gonna define them ok so Stone got by smelting cobblestone is gonna be called Fake Stone, and Silk touched stone we will call it Real stone
Only can get real stone by using silk touch only I think want to try tnt to see if I can get real stone that way But U cant trade with fake stone and u cant combine it with real stone my theory is That the problem lies with the Furnace coding.

Also or is it another tile produced intirly Why make a new tile aka two differnt types of stone but differnt id Make it feed to og tile Cause fake stone camt be traded with the masons.
