This AMACO Excel kiln comes with a timer and $70 worth of Amaco® glazes. The kiln fires to Cone 10m and it is designed to be convenient and exacting. The hinge is tough and spring loaded to make it easy to open and close. You can also get the optional EZ-LIFT for even more convenience. The firing chamber has a capacity of 4.7 cubic feet and is 18" deep with a 23 3/8" diameter. The firebrick is 2.5". A steel bar keeps the lid secure as you load and unload the kiln, and it allows for two positions. There are four Kanthal A-1 elements and a 7-foot cord for convenience. Choose between infinite control switches and a Dawson timer or a Select FireTM controller. There is a two-year warranty on this kiln.
