CRUCIBLE KILNS / MELTING FURNACES

A glass crucible kiln, glass furnace, or melting furnace is a high-temperature, pot-shaped container used to melt glass to a molten, flowing state - essentially a [glass melting pot or smelter - in a furnace or kiln. These electric crucible kilns accommodate one or more crucibles - a glass blowing crucible setup - for melting your glass for blowing, doing roll-ups, or pouring open-face castings in another kiln. These kilns can also be used for melting other low-temperature materials. 

Crucible kilns and melting furnaces operate for extended periods at high temperatures, and may experience a shortened lifespan of heating elements. We recommend reaching out to us for a set of backup elements when you purchase or shortly after to ensure you have what you'll need for uninterrupted operations.

    Frequently Asked Questions

    Frequently Asked Questions for Large Kilns
    What counts as a large kiln for pottery?

    A large kiln in this collection has an interior roughly 17 to 24 inches wide and deep, giving you room for tall vases, big platters, and multi-shelf production loads. These are studio and small-business kilns built for higher volume than home-size models.

    How much does a large pottery kiln cost?

    Large 17 to 24 inch kilns cost more than small or medium models because of their bigger chambers, heavier elements, and higher power draw. Price depends on cone rating, controller, and brand, so compare current listings in this collection for accurate figures.

    Do you have large electric kilns for sale for commercial use?

    Yes. This collection includes large electric and commercial-grade kilns suited to studios, schools, and small production shops. They handle frequent firing cycles and larger loads, so look for a high cone rating and a programmable controller for repeatable results.

    What electrical supply does a large kiln need?

    Large kilns almost always require a dedicated 240V circuit, and the bigger models may need 30 to 60 amps or more. Confirm the exact voltage and amperage on each listing and have an electrician verify your supply before installation.

    How big a kiln do I need for tall pottery pieces?

    Measure your tallest planned piece and add a few inches of clearance, then match that to the interior height of the kiln. A 17 to 24 inch large kiln fits most tall vases and sculptures that will not fit a medium kiln, while still being manageable for a studio.
