Orton Pyrometric Cone Chart in Fahrenheit and Celsius — The Studio Manager. If the target cone's final position after firing is between 25 and 75 degrees then you have selected the correct cone for your kiln's profile cone, so the temperature values for a self-supporting cone can be used to determine an equivalent small cone temperature by subtracting 7-10 degrees C (or 12-18 degrees F)
