Cone Temperature Chart For Ceramics

As discussed above the equivalent cone temperature depends upon how fast one gets to it.

Cone temperature chart for ceramics. Generally speaking the temperatures in the 108 f hour column are used when discussing ceramics porcelain and china. Temperature equivalent chart for orton cones cone 022 14 pyrometric cones have been used to monitor ceramic firings for more than 100 years. Calculate kiln cone temperature for cone 022 to cone 10 based on the kiln s heating rate. The cones often used in sets of three are positioned in a kiln with the wares to be fired and provide a visual indication of when the wares have reached a required state of maturity a combination of time and temperature.

Kiln cone temperature calculator. Mid fire earthenware should be fired between cone 2 and cone 7. Although cones do not actually measure temperature cone bending behavior and temperature are related. This is the most common temperature range for industrial ceramics.

Pyrometric cones are pyrometric devices that are used to gauge heatwork during the firing of ceramic materials. A cone 01 needs less heat treatment than cone 1 and cone 020 needs less than 019. For mid range material a kiln should be firing at a temperature between 2124 and 2264 1162 1240. Mostly yellow with a hint of orange.

Please note that the cone chart gives 3 different temperatures for each cone number. It is important not to confuse the lower maturing cones and bars whose numbers begin with an 0 with the higher cones and bars not containing this prefix. They are useful in determining when a firing is complete if the kiln provided enough heat if there was a temperature difference in the kiln or if a problem occured during the firing. Placing a small cone or bar cone into a kiln shutoff device kiln sitter will not always produce the desired temperature stated on the cone chart.
