It is the cracking that occurs in fired ceramic bodies as a result of a thermally induced stress and is caused by a ware cooled too quickly after it has been fired although usually occurring during cooling dunts can also be caused by excessively fast heating rates. Heating dunts can be recognised by rounded. Dunting generally refers to cracking that occurs in ceramic ware as it is cooled in the kiln. Dunting often exhibits itself as simple hairline cracks but ware can fracture into pieces.

Dunting is a fault that can occur during the firing of ceramic articles. These cracks appear as long clean body cracks with sharp edges. At these inversion points the structure of the silica molecules. The first occurs as you cool through the first silica inversion at 1063 degrees f.

It is the cracking that occurs in fired ceramic bodies as a result of a thermally induced stress and it is caused when a ceramic ware cools too quickly after it has been fired. There are 3 main reasons why cooling dunts occur. Dunting is cracking associated with too rapid a cool down of the kiln. Dunting is cracking associated with a very fast cool down of the kiln.

The reasons for that cracking can be many.
