Unlike most test kilns the GlazeTech is designed to run on 240V but still only requires a 20 Amp breaker (208V models require a 30 Amp breaker). This gives us the power we need to design a truly useful chamber size. Its square design makes it perfect to fire test tiles on multiple levels and with its 9” depth you can actually test short cylinders to see how your glaze performs on a vertical surface.
