Ceramic Tile Thermal Expansion

There is a rich mans and poor mans way to fit glazes the latter might be better.

Ceramic tile thermal expansion. These are thermal expansion curves for body engobe and glaze from a dilatometer a device that measures it against increasing temperature. The coefficient of linear thermal expansion clte of any material is the change of a material s dimension per unit change in temperature. The center line is the engobe. The lower line is the glaze.

The coefficient of thermal expansion or clte coefficient of linear thermal expansion. Special thanks to reader eric p e. Expansion values vary depending on the material being heated. Fine ceramics also known as advanced ceramics have low coefficients of thermal expansion less than half those of stainless steels.

Understanding thermal expansion is the key to dealing with crazing or shivering. Almost any fired ceramic object experiences expansion as it is heated and contraction as it is cooled. With a sintering temperature of 950 c the miba based glass ceramic tiles demonstrated high mechanical performance capable of satisfying ceramic wall tile requirements i e bending strength 12 mpa and thermal expansion coefficient 9 10 6 c schneider 1991. The upper line is the body.

Potters can learn from how glazes are fit on ceramic tile.
