How do kilns get so hot?

Fuel-burning kilns like gas, wood, and oil burn combustible material to heat the inner chamber. Electric kilns are lined with coiled metal elements, through which a current flows. The resistance in the coil creates heat. This heats the chamber using conduction, convection, and radiation.

Can kilns explode?

But why do pieces explode in the kiln? The pressure from the steam, and nowhere for it to escape, causes the piece to explode. If there’s too much moisture in your greenware, especially moisture inside hollow air pockets within the clay, you run the risk of having your greenware explode.

Do electric kilns need ventilation?

All kiln firings produce fumes by burning off organic material from either the clay body or glazes. Without proper kiln venting, these vapors will leak into the kiln room and become a health hazard. Sulfur fumes are particularly irritating, producing a burning sensation in the eyes, nose, and lungs.
