Screenshot by Lightshot just a quick view of what i made today.. actually got to meet the new 1.8 block
You make 2 diorite with 2 cobblestone and 2 raw quartz in a 2x2 cross. You make 2 andesite with 1 diorite and 1 cobblestone. You make 1 granite with 1 diorite and 1 raw quartz. You can get Polished Diorite/Andesite/Granite by putting 4 of the regular block into a crafting square (you get 4 polished stone back).
