A home pottery kiln is a bigger commitment than a wheel, and the first decisions are voltage, cone rating, and ventilation. A 120V kiln plugs into a standard outlet with no electrical work, while 240V kilns fire hotter and bigger but need a dedicated circuit and an electrician. Cone 6 covers bisque and most mid-range stoneware and glazes, while Cone 10 adds porcelain. A digital controller automates the ramp and hold, and every kiln needs proper clearance from combustibles and active ventilation, since firing releases fumes.

Seattle Pottery Supply 12x13 Electric Kiln (240V, Cone 10)
The same brand and controller but a taller 13 inch chamber and Cone 10 ceiling for porcelain and high-fire stoneware. It requires a dedicated 240V circuit, so budget for an electrician, a good step up once you outgrow the 120V test kiln.

Seattle Pottery Supply 18x18 Electric Kiln (240V, Cone 10)
A large 18 by 18 inch chamber for firing full loads of dinnerware and larger pieces, needing a 240V line on roughly a 40 amp breaker and serious ventilation. Overkill for a first kiln, but the pick if a garage studio is the goal.
