Common questions
What's the largest piece I can fire in the GTS 23?With a 23.5" diameter chamber, you can comfortably fire circular pieces up to about 22" or square pieces around 16" x 16" with proper clearance from the walls. The 13.5" depth accommodates stacked shelves for multiple smaller pieces or tall sculptural work. Always leave at least 1" clearance around pieces for proper heat circulation.
Why are top and side elements important for glass?Top and side firing elements are essential for glass work because they heat the glass surface uniformly and provide heat to the lower kiln portion, which helps reduce and eliminate bubbles. This configuration prevents uneven heating that can cause thermal shock, cracking, or incomplete fusing. The GTS 23's element placement is specifically engineered for optimal glass firing results.
How does the Quiet Drive Solid State Relay improve my firing?The patented Quiet Drive relay fires up to 60 times per second versus the 10 times per second limit of mechanical relays, delivering incredibly tight temperature control for consistent results. The zero-crossing technology turns elements off only when voltage is at 0V, extending element life and reducing energy consumption. With no moving parts, it never needs replacement, saving you money and maintenance time over the kiln's lifetime.
Can I use this kiln for both fusing and slumping?Yes, the GTS 23 is designed for the full range of glass techniques including fusing, slumping, draping, painting, and casting. The 1700°F max temperature covers all standard glass working temperatures, and the precise controller options allow you to program the different ramp rates and hold times each technique requires. Many studios use this as their primary all-purpose glass kiln.
Does buying from Peach State Pottery affect my warranty?No. We are an authorized Evenheat dealer. Your two-year warranty is fully valid and you have direct access to Evenheat’s support team. Buying from an unauthorized seller can void your warranty entirely.
Not sure if the EH-GTS-23 is right for you? We’re authorized Evenheat dealers based in Atlanta. Call, email, or chat — we’ll give you a straight answer about specs, sizing, and accessories before you spend a dollar.
