CLAY:
Claying Mixture For Forges.
The materials should be thoroughly mixed dry and then wet down to the consistency of common mortar, constantly stirring the mass as the wetting proceeds. A rough mold shaped to fit the tuyère opening, a trowel, and a few minutes’ time are all that are needed to complete the successful claying of the forge. This mixture dries hard and when glazed by the fire will last.
