Choosing the Right Kiln Size

When investing in a pottery kiln for ceramics, one of the most important decisions you’ll make is choosing the right size. Kilns are an important piece of equipment in the process of creating ceramics. They determine how much you can produce, how quickly you can work, and what kinds of forms you can create. At Bailey Pottery Equipment, we carry a full range of electric and gas kilns to support every ceramic artist, from beginners ready to move clay firing to their home to production potters firing daily. This guide goes over the many different kiln sizes that are available. It covers test, small top-loading, medium top-loading, large top-loading, and commercial-duty models. We'll highlight the benefits and reasons to consider each.

Premium Test Kilns for Ceramic Artists

Best for: glaze testing, jewelry makers, miniatures, and high-production studios A test kiln is a compact electric kiln that typically operates on 110-volt household power and uses 15 amps or less. Its compact design makes it a convenient option for anyone working in a limited space or with less available amperage.

Benefits of Test Kilns:

• Perfect for glaze development – Safely test new glaze recipes on small samples.

Even large-scale studio potters rely on test kilns for trial runs, glaze testing, and firing quick orders. Their speed and efficiency make them an indispensable tool across all skill levels.
