Dunting In Ceramic

Dunting is cracking associated with too rapid a cool down of the kiln.

Dunting in ceramic. Most dunting however is caused in cooling. At these inversion points the structure of the silica molecules. 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. Dunting is cracking associated with a very fast cool down of the kiln.

The reasons for that cracking can be many. Heating dunts can be recognised by rounded. 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. According to wikipedia dunting is a fault that occurs during the firing of ceramic articles.

Dunting is a special type of crack which occurs from stresses caused during firing and cooling. 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. Dunting often exhibits itself as simple hairline cracks but ware can fracture into pieces. These cracks appear as long clean body cracks with sharp edges.

If the ware is glazed the glaze edges are sharp. Heating dunts can be recognised by rounded. Dunting is a fault that can occur during the firing of ceramic articles. These stresses primarily occur during two critical points of firing called silica inversions which occur at 1063 degrees f 573 degrees c and 439 degrees f 226 degrees c.

They may be vertical horizontal or spiral. There are 3 main reasons why cooling dunts occur.
