Ceramics

Dunting is a fault that can occur during the firing of ceramic articles. It is the "cracking that occurs in fired ceramic bodies as a result of a thermally induced stress" [1] and is caused by a "ware cooled too quickly after it has been fired"[2][3].

Although usually occurring during cooling dunts can also be caused be excessively fast heating rates. Heating dunts can be recognised by rounded edges to the cracks as the glaze matured after they occurred, whereas cooling dunts have sharp edges [4][5].

It has been found that bodies formulated with quartz rather than flint were more susceptible to dunting, especially on re-fire. It was postulated this may be related to the lower Young's modulus of the quartz based bodies.[6]

Noun

A dunt - a dull-sounding blow (Scots)[7].
