clay smithing templates

Using clay to replicate smithing templates:

Step 1: craft a "template stamp" (uses a smithing template [or a banner pattern?], 2 copper, 1 amathyst shard, and 1 smooth stone slab) 

Step 2: Craft a stamp with some clay and 2 copper and a smooth stone slab to make a mold (or craft it with an ink sac and paper to make a banner pattern) The stamp is not consumed, though perhaps it loses some durability?

Step 3: bake the new smithing template in the furnace, and it will become useable. (it may need to be baked in a blast furnace or a new "kiln")

Total: 1 smithing template (may or may not be consumed), 4 copper (we need more uses for it), 3 clay (1 clay, 2 clay crafted into bricks), 1 amathyst shard, 3 cobble (baked to make smooth stone for the 2 needed slabs, can be reduced to 1 cobble if you have a stonecutter), 13 items worth of fuel (used to smelt items necessary for crafting, reduced to 9 if you used a stonecutter to reduce the smooth stone requirement, and would be increased significantly if a blast furnace it required.)

A new kiln block could be used to craft clay buckets, clay bottles, clay pots, flower pots, bricks, terracota, glazed terracota, glass, glass bottles, etc.
