Any color may be given with ground bricks or pottery.

Another cement of the same kind.
Mix 4 parts of fine borings or fillings of iron with 2 parts of potter's clay, and 1 part of pounded potherds, making them into a paste with salt and water. If allowed to concrete slowly on iron joints, this cement becomes very hard.
