Summary

Reversible thermal expansion (RTE) is an important tool for measuring characteristics of a whiteware formula. This paper discusses the different RTE characteristics of low-fire, stoneware, porcelain, and ovenware ceramic bodies. An example of formula development to improve thermal shock qualities of an existing ovenware body is discussed. Reversible thermal expansion can be important in determining the source of dunting in fired ware. The paper discusses important features of the RTE curve and how they relate to results of the firing curve. It also includes a brief discussion on glaze fit and body fit as it relates to RTE differences of each.
