Body Thermal Expansion Property

Materials in this class are added to bodies to reduce their thermal expansion by simply diluting a high expansion matrix by introducing particles having low expansion. It is thus implied that these materials are added as grog and are not fired high enough to change their mineralogy and therefore thermal expansion properties.

Co-efficient of Thermal Expansion
The co-efficient of thermal expansion of ceramic bodies and glazes determines how well they fit each other and their ability to survive sudden heating and cooling without cracking.
