CLAY: (f) Dry Repairing.
Clay dry repairing
a) Scratch both parts that have to be joined.
b) Wet them with water, put on a thin layer of watered down damp clay, pushing it in to the inlets left by the scratching, leaving a thin layer of workable clay.
c) Join the two pieces by pushing them together and hold tightly or weigh them down until they stick together. Clean off the clay that has been squeezed out round the edge of the joint. When dry, they should have stuck together and can then be fired. This is good for repairing corners and edges that have been chipped off.
