Electric vs. Gas Kilns: Which Is Right for Your Pottery?
Ask any group of potters whether they prefer electric or gas kilns and you'll start an argument that goes on for hours. Both have devoted fans. Both produce beautiful work. But they work very differently — and one is almost certainly a better fit for your situation.
Here's the honest breakdown.
How Electric Kilns Work
Electric kilns use coiled resistance elements (similar to a toaster, but industrial-grade) to heat the chamber. The atmosphere inside is oxidizing — meaning there's plenty of oxygen throughout the firing. This makes electric kilns exceptionally predictable and clean. Colors come out bright and consistent. Glazes do exactly what they're supposed to do.
Electric kilns are also quiet, require no gas lines, and can be used indoors with proper ventilation. They're the go-to choice for home studios, schools, and production potters who prioritize consistency.
How Gas Kilns Work
Gas kilns burn propane or natural gas. They can be fired in oxidation (plenty of air) like an electric kiln, but the magic of gas is reduction firing: restricting air so the flame "steals" oxygen from the metal oxides in your clay and glazes. The results — celadon greens, tenmoku blacks, copper reds — simply can't be replicated in an electric kiln. If you've ever seen a wood-fired or reduction-fired piece and wondered how the potter got that depth and variation, this is the answer.
The tradeoffs: gas kilns need outdoor or heavily ventilated installation, require a gas line or propane tank, and demand more hands-on skill to fire. Results are less predictable — which is exactly what many potters love about them.

Why ProKilnSupply Focuses on Electric Kilns
The kilns we carry — Olympic, Evenheat, Jen-Ken, Cress, and Aim — are all electric. That's not an accident. Electric kilns serve the vast majority of ceramic artists: home potters, schools, production studios, and glass artists. They're safe for indoor use, highly controllable, and backed by U.S. manufacturer warranties.
If you're set on gas firing, we respect that — but if you're on the fence, there's a reason so many professional ceramicists run an electric kiln alongside their gas kiln. You get the best of both worlds.
Which Should You Buy?
Buy electric if: you're in a home studio, you teach ceramics, you fire glass or low/mid-fire clay, or you want consistent, repeatable results. Buy gas if: you're an experienced potter chasing reduction effects, you have outdoor space and a gas setup, and you're okay with more unpredictability.
