I'm thinking about buying an old non-working electric kiln to convert to gas (like Simon Leach). My question is about the max temperature of a kiln. Is the max firing temperature of a kiln based solely on the limits of its electrical components, or can the body/case of the kiln not physically handle it? If I converted a kiln that said, "Do not operate past 2000 degrees", would cone 10 firings damage the structure of the kiln? (The kiln I'm considering is an old Evenheat 3220)
