Spacious Chamber for Glass Artists with the GTS 18 Personal Studio Kiln
The Evenheat GTS 18 gives you space to take on bigger projects without overcomplicating your setup. Its 17.5″ round chamber and 13.5″ depth are well-suited for firing large plates, deep slump molds, drop rings, and thicker fused builds—anything that feels too tight in a smaller kiln.
It’s built with full firebrick insulation for even, stable heating and smooth annealing. The Quiet Drive solid-state relay delivers clean, consistent temperatures that help protect your elements and give you reliable results from one firing to the next.
Setup and maintenance are straightforward. The Swing View control panel tilts where you need it. The two-position lid vent gives you more control over cooldowns and fume release. And the relay access port makes swap-outs simple with just a screwdriver. Whether you’re firing once a week or every day, the GTS 18 is a dependable studio kiln that gets the job done.
