The only new kiln technology is the electric kiln. Unlike other methods which utilize a fuel for operation, electric kilns run by coiled wires that bring about heat. A toaster operates on the same principle. A lot of the modern electric pottery kilns are equipped with electronic shut off devices, called kiln sitters, to monitor the firing process. Still, any kiln must never be left unattended.
