This requires the unusual, and sometimes difficult, process of cooperation between the school's science and art departments. Small electric pottery kilns are quite adequate for making superconductors, although most will require some minor modifications. Any modifications that are required will not impair the use of the kiln for pottery. In fact, the modifications will only enhance their use as a pottery kiln. Some kilns do not have a pyrometer for measuring temperature.
Suitable pyrometers are available from most kiln dealers at a very reasonable cost.
Some inexpensive pyrometers are not very accurate, but even the relatively inaccurate pyrometers are usable if they are calibrated to a suitable calibration reference at a temperature near 950 degrees Celsius. The pyrometric cones commonly used in pottery kilns are a suitable calibration reference. These cones are much more accurate than the temperature indicators on most pottery kilns. This is the same controller that is used in 95 percent of all electric kitchen ranges with rotary controls. They can be installed on an electric pottery kiln by anyone familiar with electrical wiring.
