So many glazes appear as they do because of the firing schedule (especially the cooling curve). Imagine getting an awesome result out of a kiln and not knowing (or being able to replicate) the exact firing schedule that produced it. This device reads and records the temperature once per minute. It is a Raspberry Pi computer with camera, Wifi and custom software I am developing. It costs about $100 (with the Lego case and GoPro compatible gooseneck mount). Because the device is a full-power Linux web server I can login, will be able to see the list of schedules and download any into my Insight-live.com account. And then I can link that firing it to photos of glaze test results!
Designing a good kiln firing schedule for your ware is a very important, and often overlooked factor for obtained successful firings.
In ceramics kilns the firing schedule of a kiln is typically managed automatically by an electronic device called a kiln controller. These are especially common on electric kilns.
