Cone 6 vs cone 10: choosing a firing temperature

Cone 6 (about 2232°F / 1222°C) and cone 10 (about 2345°F / 1285°C) are the two dominant stoneware ranges. Both make durable, food-safe ware. The choice is mostly about economics and aesthetics, not quality.

The case for cone 6

• ·Lower energy cost per firing and faster cycles.
• ·Far less wear on elements and kiln furniture — electric kilns love it.
• ·Modern cone 6 glazes rival high-fire results; the old 'cone 6 looks cheap' reputation is outdated.

The case for cone 10

• ·Classic reduction effects — shinos, celadons, copper reds — that are hard to fully replicate at cone 6.
• ·Often used with gas kilns where atmosphere is the point.
• ·Some potters prefer the body vitrification and 'ring' of a high-fired pot.

What it means for a production potter

If you're firing an electric kiln and selling functional ware, cone 6 usually wins on cost and kiln longevity without sacrificing durability. If your work depends on reduction atmosphere effects, cone 10 gas earns its higher running cost. Either way, match your clay body and glazes to the cone — that's non-negotiable.
