Brick Ovens

So.  Brick Ovens.  Sounds interesting enough.  They are crafted with a Furnace in the middle of the grid, 5 Brick Blocks around the top, and Wood Logs covering the bottom.  The brick oven gives less EXP when used, but smelts things like Sand, Cobblestone, and other odd smeltable things a lot faster.  However, you cannot fuel the Brick Oven with Coal.  You are required to use wood or Charcoal, just to give those items more of a use.  Villagers can use the Brick Oven to become a Pottery Villager.  They can trade you things like Bricks and Clay.  They can also give you Colored Bricks, which would be great for the builders of Minecraft.
