This is the AMACO Excel Kilns - EX-365 with the EZ-lift optional add-on that allows for easy opening and lifting of the lid with its heavy duty, spring loaded hinge. The firing chamber has a 22 3/4-inch diameter and is 27-inches deep, making it big enough for larger sized projects. The reversible slabs give extends the life of the kiln. This kiln allows you to choose between an "Infinite Control Switch," "Select-FireTM Computer-Control" or "Dawson-Kiln-Sitter/Limit-Timer", which gives you flexible options on what kind of controls you want for your kiln. The generous power cord (7-feet) makes sure you can place your kiln in a convenient location inside your studio. Finally, the six Kanthal A-1 elements are some of the best quality heating elements on the market.
