WHY IS CLAY FIRED? Clay becomes pottery at temperatures at about 1,000 degrees F (the beginning of glowing red heat – about 540 C). Traditionally, tribal earthenware is fired to about 1,400 degrees F (760 C). Heat removes the molecular water in the clay.
According to Wikipedia, Terracotta is a type of earthenware; it is a clay-based unglazed or glazed ceramic, where the fired body is porous.
Terracotta and tile were used extensively in the town buildings of Victorian Birmingham, England. Terra cotta was marketed as a miracle material, largely impervious to the elements. Terra cotta, however, can indeed be damaged by water penetration or exposure or fail through faulty design or installation.
After undergoing the intense process of glazing, when the body of the terra-cotta item cools down, and its outer surface turns into a smooth and solid surface, then this glazed exterior results in becoming a tight surface, which is impervious to water. It also holds liquid for a much longer time.
Does terracotta break in heat?
