Proper set-up and maintenance of your kiln is critical to reliable and accurate clay firings. Understanding your kiln and its intricacies will all

It is important to realize that the Orton Foundation does not test cones under all of the many firing conditions where cones might be used successfully nor is it possible for the Foundation to know the critical nature of the firing control needed for all types of products. Changes in raw materials used in manufacturing of pyrometric cones may cause performance changes at firing rates or atmospheres different from Orton's standardizing conditions. Therefore the Orton Foundation encourages users with critical applications to check the performance of cones under their actual conditions of use. Each package of cones is identified with both cone and batch numbers so that the user may independently determine whether a new batch performs the same as the batch presently used before putting the new cones into service. By doing this, any changes in performance can be observed and recorded, thus maintaing product quality. If questions arise, please contact the Orton Foundation and one of our engineers will try to answer them

Kiln-sitters are a device for automatically shutting off your kiln when reaching a predetermined temperature or cone number.
