Olympic Kilns Crucible 18 Glass Kiln

Introducing the Olympic Kilns Crucible 18, a powerhouse kiln designed for serious glass artists who require precision, durability, and safety in their high-temperature work. Whether you’re melting glass for intricate designs, sculptural projects, or large-scale productions, this kiln provides the robust performance you need to achieve professional-quality results every time.

Built for High-Performance Glass Melting
With interior dimensions of 17.5″ wide by 18″ deep and capable of firing up to 2350°F, the Crucible 18 is engineered for the most demanding glass melting tasks. This kiln is perfect for artists working with large volumes of glass and seeking a reliable, high-temperature environment for consistent results. Its thick 3” brick walls and 1” fiber blanket offer exceptional insulation, while the stainless-steel jacket ensures long-lasting durability.

Advanced Features for Safety and Precision
The Crucible 18 is designed with safety in mind. It features an automatic lid shut-off that turns off the elements when the kiln lid is opened, ensuring safe operation. The counter-weighted lid and stainless-steel trough make gathering glass from the crucible both safe and efficient, protecting both the artist and the kiln. Additionally, the 3” thick, separate bottom can be turned over or replaced easily if damaged, further extending the kiln’s lifespan.

State-of-the-Art Temperature Control
Precision is key in glassmaking, and the Crucible 18 delivers with the Digital KilnStar controller, which offers intuitive and precise control over your firing process. With programmable ramp-hold settings, the KilnStar allows you to store and repeat firing schedules with accuracy. The simple interface lets you adjust temperature and time with ease, ensuring that your kiln reaches the exact conditions needed for your project.

For those seeking even more advanced control, the Genesis touchscreen controller is available as an upgrade. The Genesis provides additional features such as delay start, preheat, and extra ramp-hold programs, allowing for even greater flexibility and customization in your glassmaking process.

Designed for Efficient Element Operation
The Crucible 18’s element system is optimized for both performance and efficiency. Featuring four sets of elements, this kiln heats up rapidly, with two sets required to maintain temperature and two in reserve to prevent cooling if an element fails during firing. This design ensures that your kiln continues to perform efficiently, even during intensive use.

Customization and Durability
The Crucible 18 offers customizable options to enhance its performance further. The kiln’s gaskets can be cut to fit the size of your crucible when ordered, ensuring a perfect fit for your specific needs. With a solid stainless-steel construction and a durable, counter-weighted lid, the Crucible 18 is built to withstand the rigors of daily use in professional studios.
