Crafted from earth by the hands of Sullen Whimsy with the aid of water, lain to rest in the air to then be hardened by fire. The elements come together to create a cauldron for Black Forge. These 16oz mugs are handmade with love from stoneware, and finished with a matte black glaze. The Black Forge rune is detailed in bronze to give the effect that it had been branded into the piece. Microwave and dishwasher safe.
