@pullerrush(View Post) Give it some uses; currently this is just a solid with the ordinary propeties of breaking into its powder form under pressure. BRCK, QRTZ, GLAS, BMTL ect. All of those elements have that same propety of CLAY.
CLST is actually a very good representation of what clay really is. If you have dry clay, it is a powder. When you get it wet, it turns into a paste. When you heat that paste up to extreme temperatures, it will either harden into a brick like substance, or melt. When you cool the melted paste, it turns into a brick like substance. All of those properties are already in TPT. CLST even clumps together in TPT and can actually be made into a "solid" as well. The only thing that I think needs to be changed is the color of brick which is fine the way it is because of the deco-layer.
