Like all GL Series models, the GL18ATSD surrounds your glass with three-directional heating:

• Top elements are recessed into pinless grooves for clean construction and reduced maintenance.

• Side elements span all three walls in recessed brick channels, providing precise vertical heat control—ideal for drop molds and tall forms.

• Door elements add critical front-end heating, allowing advanced techniques such as embossing or glass manipulation with the door cracked open.

This multi-directional system ensures even heat distribution and excellent results, whether you're firing delicate jewelry or sculptural glass forms.

• 3-inch insulating firebrick lines the chamber for consistent thermal performance and slow, controlled cooling.

• The kiln body is reinforced with a heavy-gauge steel case, offering long-term durability.

• A ventilated switch box, air gap, and double heat shielding keep electronics cool during frequent use.

• Nickel-plated copper wiring, protected in high-temperature insulation, ensures safety and electrical reliability over time.

• Two peepholes on the rear wall let you observe the firing process directly, with plugs included. (Note: Some international models may not include peepholes unless specified at time of order.)

• Spring-loaded door latch and a recessed brick edge ensure a tight, secure seal throughout the firing cycle.

• The door remains stable on a reinforced hinge shaft, and four integrated handles make the kiln easy to move when needed.

• The open-back base helps dissipate heat efficiently after firing.

The GL18ATSD is the ideal studio companion for:

• Fusing dichroic glass jewelry like earrings, pendants, and bracelets

• Slumping shallow dishes or curved panels

• Drop-out vessels using sidewall heat

• Glass raking and embossing through the front door

• Exploring casting, inclusions, and pâte de verre techniques

As glass instructor Becky Johnson puts it, “The transformation of the glass inside the kiln is magical and mystical. To be some part of that process is a true gift.”

This model is equipped with the SENTINEL Smart Touch controller, offering advanced temperature programming, real-time monitoring, and full access to Paragon’s power ratio heat balancing feature. Easily adjust the ratio between top and side/door heat in 10% increments to suit your specific glasswork.
