Exodus 8:3

Ovens] These were large earthenware jars or pots about 3 ft. high, which were heated by being filled with burning brushwood. The dough was baked by being laid in thin layers on the hot sides of the jar. Sometimes the oven consisted of a hole dug in the ground outside the house and plastered with clay. It was heated in the same manner as before, and after the fuel was withdrawn, the oven was wiped out and the dough pressed to the hot sides. Kneading-troughs] wooden bowls.
