Abstract
A long wavelength counter top radiation oven in which the top and bottom surfaces of the oven cavity are formed by metal radiator panels each heated by an electric resistance heating element. A low temperature cured ceramic surface coating applied to each panel gives it a surface emissivity near unity to enhance the thermal efficiency of the oven. Separate high temperature thermostats control the upper and lower heating elements independently.
