GTT Mirage: the 40-jet, two-stage Triple Mix workhorse for large boro and production

The GTT Mirage is one of Glass Torch Technologies’ big-flame bench torches — a two-stage, 40-jet Triple Mix burner built around a Lynx-style center fire with two outer rings stacked around it. The result is a torch with high power across glass types: a fine, controllable flame at the center and the heat base to push well into large-boro and production work. It’s where the GTT line stops being a detail tool and becomes a serious production burner, while still keeping the family’s clean surface-mix behavior.

What the two-stage Triple Mix flame gives you

Triple Mix is GTT’s surface-mix technology: fuel and oxygen meet at the face of the torch, which keeps the mixing chamber cool and gives a clean, penetrating flame that drives heat into the core of thick glass instead of just washing the surface. Stacking two outer rings around a Lynx center lets the Mirage scale from a finer flame up to a wide, powerful one. To understand why that penetrating quality matters for heavy boro, read soaking vs penetrating flame, and for the underlying tech see GTT Triple Mix technology and surface mix vs premix torches.

Who the Mirage is for

The Mirage is squarely an advanced torch for large borosilicate and production — makers building thick functional pieces and tubes who need a deep, repeatable heat base and don’t want to fight their torch for it. It isn’t a detail-only burner and it isn’t a beginner’s first torch. If you’re weighing it against GTT’s big hand torch, see the Mirage vs Delta Elite comparison.

Glass, fuel, and oxygen

The Mirage burns propane or natural gas with oxygen and is rated for high power across both soft glass and boro. The trade for that output is appetite: this is a high-output two-stage torch, so it wants a substantial oxygen supply — realistically tanked oxygen or multiple concentrators rather than a single small unit. GTT doesn’t publish the Mirage’s exact LPM figures, so size your oxygen around the work you actually do and confirm the numbers with GTT before committing. Start with how many LPM does my torch need.

Where it sits in the GTT lineup

The Mirage sits in the upper-middle of the range. Below it, the two-stage Phantom wraps a single 15-jet ring around the Lynx center for medium boro; the Mirage adds a second ring and the heat for large boro and production. Above it, the three-stage production burners (Delta Mag, and the larger Triple Mix torches) push further still, and the Delta Elite brings comparable power in a hand-torch form. Because it’s built on the same Lynx center, the flame behavior you know from smaller GTT torches carries straight up.

Before you buy

Budget for the whole system, not just the torch: an oxygen supply sized to a high-output torch, the correct propane or natural-gas regulator, flashback arrestors on both lines, didymium eyewear, and serious ventilation. New to plumbing a torch this size? Start with the fittings, hoses & connectors guide and the glass torch safety setup guide, and think through oxygen concentrator vs tanks early.

Editor’s note: spec details reflect GTT’s own materials. GTT doesn’t publish the Mirage’s exact oxygen flow (LPM) or current pricing, so confirm those specifics with GTT before purchasing.
