A method of checking the 'heat work' achieved by the kiln.

Cone 04 temperatures are based on a kiln firing at 15°C, 60°C and 150°C degrees per hour when climbing at the last 100 degrees to the top (target) temperature.
• 15°C - 1046°C
• 60°C - 1063°C
• 150°C - 1077°C
Orton Cones are a ceramic aid that when heated in a kiln, will bend. It will give a value of 'heat work' which is a calculation of both temperature and time.
These can be used in oxidisation (electric kilns) and in reduction with other fuelled kilns*.
See further advice in our knowledge base on 'Orton cones'.
*except between values of '010' to '3' as they contain iron oxide. Use iron free ones for firings between this range.
It works!
