Choosing a Kiln for a Studio

The kiln is the heart of a pottery studio and usually its single most important purchase. Get the capacity and power right and it quietly does its job for years; get them wrong and you'll either be firing constantly to keep up or paying to run a kiln that's too big half-empty. Here's how to choose a kiln for a studio.

Size it around your weekly output, not your floor space

The right capacity comes from how much work your studio produces each week, not how much room you have. Estimate the number of active members and students, how often each makes work, and remember that everything is fired twice — a bisque firing and a glaze firing. A studio that fills a kiln every few days needs more capacity (or a second kiln) than one firing weekly. Our Kiln Size Calculator and free kiln selection service will translate your numbers into a recommended capacity.

Top-loading vs front-loading

Most studios start with a top-loading kiln: they're more affordable, lighter, and easy to load from above. Front-loading kilns cost more but are kinder on your back, easier to pack precisely, and tend to suit larger or busier studios and anyone firing heavy or tall work regularly. If staff or members will be loading all day, a front-loader's ergonomics earn their keep.

Single-phase vs three-phase power

This is the decision that catches people out. Smaller kilns typically run on a standard single-phase 13A or 32A supply. Larger kilns — and the kind of capacity a busy studio needs — often require three-phase power. If the building doesn't already have three-phase, installing it can be costly and slow, so confirm your supply before you choose a kiln, not after.

Controllers and firing flexibility

A programmable digital controller is worth having in a studio — it gives repeatable firings, ramp and soak control for different clays and glazes, and lets staff set a firing and walk away. For a teaching studio especially, repeatable, foolproof programs save a lot of grief.

When to run more than one kiln

Two smaller kilns can beat one large kiln for a busy studio: you can run a bisque and a glaze firing independently, keep turnaround fast, and you're not down entirely if one needs maintenance. Against that, two kilns mean more power demand and more floor space. If you're firing daily, it's worth modelling both options.

Don't forget kiln furniture and siting

Budget for shelves, props and kiln wash — they're essential and add up. Site the kiln with safe clearances and proper ventilation or extraction, on a non-combustible floor, away from where people work closely. See our guide to kiln ventilation and safety for the detail.
