The GL24ATSD surrounds your glass with heat from all directions:

• Lid elements are mounted in pinless grooves—held securely without clips for a cleaner interior and lower maintenance.

• Wall elements span all three interior sides in six horizontal rows and are protected in recessed grooves.

• Door elements ensure precise, even heat at the front of the kiln, ideal for working with challenging shapes and techniques. The hinged door always opens from the right side.

This tri-source heating system means unmatched consistency, even for large, detailed, or asymmetrical projects.

The GL24ATSD uses Paragon’s power ratio technology, allowing you to control the percentage of heat delivered from the lid versus the side and door elements. Adjust in 10% increments to fine-tune firing profiles based on your project needs. Whether you're slumping thin panels or casting deep molds, this advanced feature helps minimize cold spots and maximize firing success.

• 3-inch thick firebrick insulation retains heat and allows for slow, even cooling.

• Heavy-duty steel casing wraps the chamber for maximum structural integrity.

• Double heat shields and air gap keep electronics cool for long-term durability.

• Nickel-plated copper wiring, protected in high-temperature insulation, ensures safe, high-efficiency operation.

• Four built-in handles allow safe lifting and relocation.

• Spring-loaded door latches and a ½" recessed edge ensure a tight, secure seal every time.

• Integrated door safety switch turns off power to the elements whenever the door is open, while allowing the controller to keep running.

• Two peepholes on the side opposite the control box let you monitor the process without opening the kiln.

• Note: The GL24ATSD is not compatible with glass viewing windows due to door elements.

The GL24ATSD now includes the SENTINEL Smart Touch controller—a powerful digital interface that gives you full command over ramp-hold sequences, live temperature data, heat ratio settings, and energy usage monitoring. The sealed touchscreen is intuitive, dust-resistant, and easy to clean.

• Glass studios requiring professional-level heat control for full-size projects

• Artists working with curved forms, molds, and three-dimensional applications

• Schools and teaching studios firing daily across multiple users and skill levels

• Advanced users exploring pâte de verre, deep slumping, or multilayered designs

Like every Paragon kiln, the GL24ATSD is handcrafted in the USA with a commitment to quality, performance, and long service life. Whether you're scaling up production or refining your techniques, this kiln is built to support your creative ambitions—day after day, year after year.
