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

GTT Mirage · Bench torch · Surface mix

The GTT Mirage is a two-stage, 40-jet Triple Mix (surface-mix) bench torch built around a Lynx-style center fire wrapped in two outer rings, high power across glass types, from a fine center flame up into large-boro and production territory.

Treat the oxygen figure as a rough sizing estimate, not a specification. Depending on the model it may be manufacturer full-flame consumption, a converted flow figure, or a documented estimate, and delivered pressure and purity matter as much as flow. What actually drives a torch choice is the glass, the work, and the flame, so size your oxygen supply after you pick the torch. Prices may be manufacturer list prices or observed dealer references. Use the evidence label and sources below, then confirm the exact configuration before buying.

Overview

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 bigger 57-jet Delta Elite, 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. Our catalog carries a ~26 LPM reference converted from GTT’s flow table for the largest usable flame; size your supply to the flame you actually run and confirm with GTT. 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 more jets still (57), standard as a bench torch with a separate hand-torch version. 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 protection matched to your torch and gas supply, didymium or boro-rated eyewear matched to your glass, 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. The catalog’s ~26 LPM oxygen figure is converted from GTT’s flow table for the largest usable flame (a ceiling, not a minimum), and current configuration details should be confirmed with GTT before purchasing.

Fit and tradeoffs

Best for: Advanced makers working large borosilicate, pipes, and production who want serious, penetrating surface-mix heat with a fine center flame still on tap.

Not for: Beginners, fine detail-only work, or anyone trying to run on a small single concentrator, a high-output two-stage torch like this wants a real oxygen supply.

Pros

  • + Two-stage, 40-jet Triple Mix: a fine Lynx-style center plus two outer rings for big heat
  • + High power across both soft glass and boro
  • + Penetrating surface-mix flame that drives heat into thick glass, not just the surface
  • + Lynx-style center means the detail flame and family behavior carry over
  • + One torch covering a wide range, from a center flame up to production-scale heat

Cons

  • High oxygen appetite, plan a tank or multi-concentrator supply
  • High price band; a serious investment in the torch and the oxygen to feed it
  • Overkill for small beads and detail-only work
  • Some oxygen figures are converted from CFH and prices vary by configuration; confirm the exact setup with GTT

Flame notes

2-stage: Lynx center + two rings, 40 total jets; high power across glass types.

FAQ

What kind of work is the GTT Mirage built for?
Large borosilicate and production. It's a two-stage, 40-jet Triple Mix torch with the heat base for big tubes and functional work, while the Lynx-style center keeps a finer flame available when you need it.
Can the Mirage run on an oxygen concentrator?
It's a high-output two-stage torch, so its oxygen appetite is well beyond a single small concentrator. Our catalog carries a ~26 LPM reference converted from GTT's flow table at the largest usable flame, so plan around tanked oxygen or multiple concentrators and confirm the figures with GTT before buying.
How does the Mirage compare to the Delta Elite?
Both are high-end Triple Mix torches on a Lynx center fire, but the Mirage is a two-stage bench torch aimed at being a do-everything large-boro and production burner, while the Delta Elite runs 57 jets, standard as a four-stud bench torch with a separate hand-torch version for assembly and large work. See our Mirage vs Delta Elite guide.
Is the Mirage a good beginner torch?
No, it's pitched at advanced makers. The flame, oxygen demand, and price all point to someone already working large boro or production. Beginners are better served by a Bobcat, Cheetah, or Cricket.
Soft glass, boro, or both?
Both. GTT rates it for high power across glass types, though its center of gravity is clearly large boro and production work rather than soft-glass beads.
