Dan Longden x Treso Rig DRT712
$750A full collaboration rig built with Massachusetts flameworker Dan Longden — his linework and form language over Treso fume.

The core of the studio: clear borosilicate treated with vaporized silver and gold until the surface holds color that was never added as color.
Oil on water, heat haze over asphalt, the blue-to-amber shift you get looking through smoke at a streetlight.
Fume is the only part of the process I can't fully control, and that's the point. I set the conditions, the metal decides the rest.
Hold it up to daylight before you judge it — fume reads completely differently with light behind it.

A full collaboration rig built with Massachusetts flameworker Dan Longden — his linework and form language over Treso fume.

Heavy silver and gold fume layered over clear, worked into a full-size functional rig. Headiest piece in the current lineup.

Layback Sherlock with silver fume worked over a cobalt body — the fume shifts warm against the blue.

Straight-up fume on clear, laid-back Sherlock shape. Made on the bench at Witch DR in Salem.

Silver fume laid over deep cobalt. The color reads differently depending on how much light hits it.

Fumed body finished with an aqua azul frit cap — crushed color melted into the surface for texture and depth.

Same fumed body, forest green frit cap. Darker, mossier, and it hides fingerprints better than most.

Lava frit cap over fume — orange and rust flecks that match the rest of the ember palette.

Cherry frit cap on a fumed body — the brightest of the frit cap set.

Silver and gold fumed over clear borosilicate, layered for depth and smoke-like movement.

Lightweight silver-fumed drops. Each pair shifts color in the light, and no two are identical.

A palm-sized fumed marble — silver worked into clear so the smoke reads different from every angle. Placeholder photo, real shot coming.

Stackable fumed glass rings, sized to order. Colors shift from amber to violet depending on the light.

An end-of-day piece pulled from leftover rod — frit, fume and whatever the torch felt like. One of one, never repeated.
New pieces hit the list before the gallery.
