Tiny Tim firing chamber size: 11" wide X 131/2" deep, 6 sided, .82 cubic feet, 120 volt, 20 amp., 2.40 K.W., maximum cone 6. Small kiln for the home ceramist or studios wanting to do small firings. Not recommended for porcelain since not all homes or studios have full 120 volt power. With this size chamber the Tiny Tim would struggle to reach a full cone 6, if it would reach it at all. Tiny Tim has a Dawson Kiln Sitter as a standard feature for cone firing with auto shut off. Lid and bottom are reversible. Kiln is dropshipped via UPS.
