Radi se o tehnici vitraža
http://en.wikipedia.org/wiki/Lead_came_and_copper_foil_glass...
Lead came and copper foil glasswork are the arts and crafts of cutting pieces of stained glass and joining them into picturesque designs in a framework of soldered metal.

The traditional method uses lead came. This is the method used for centuries in Europe, mainly in religious buildings such as cathedrals, churches and monasteries, and including wealthy or aristocratic homes. In the lead came method the pieces of glass are embedded into the channels of the came, and the joints between the came strips soldered together.

U završnoj fazi dolazi do rastavljanja vitraja iz olovnih profila, rezanja stakla koji nedostaje po šablonama, slikanja na staklu bojama sa metalnim oksidima, termička obrada slikanih dijelova, čišćenje postojećih staklenih površina, sastavljanje u nove olovne profile, cinkovanje olovnih spojeva, čišćenje tekućim kitom da bi vitraj postao stabilan i vodo-otporan, i na kraju slijedi transport i montaža u postojeće okvire.

Lead Came
For nearly 20 years, we have served the stained glass industry with a high quality lead came known for it's consistency and workability. We strive to meet any special profile requirements; our original 15 sizes have increased to over 100.

Pogledajte ovde, npr. profiles and specifications, vidi se da se radi o olovnim profilima:

Sledeći tekst nažalost nije na hrvatskom jeziku ali terminologija je ista, imamo olovne profile i olovne trake (lead strips):
http://www.vitraz.co.rs/profili-i-lemovi/49-meki-lemovi
Držači stakla pri izradi vitraža (olovni profili i trake) spajaju se i zalivaju mekim lemovima.
...
U zavisnosti od veličine žljeba za popunjavanje, veličine profila, spretnosti vitražiste i snage lemilice mogu se koristiti razlićite debljine lema u obliku žice ili šipke kružnog ili trougaonog poprečnog preseka. Pri radu sa trakama (Tiffany tehnika) najbolje je koristiti žicu prečnika 3 mm ili šipke prečnika 5 mm. Pri radu klasičnih vitraža (sa olovnim profilima) takođe se koristi žica prečnika 3 mm i šipka prečnika 5 mm a za popunjavanje većih žljebova koristi se trougaona šipka 8x8x8 mm ili 10x10x10 mm.

Tiffany tehnika je obično sa bakarnim trakama ali ta tehnika je ista i sa olovnim trakama.

How to Build a Tiffany-Style Lampshade
Assembling Your Lampshade
6. Once all glass pieces fit together on the mold, they must be individually wrapped along the edges with the appropriate width of copper foil (size as per pattern), and snugly and evenly pressed over the sides, with the handle end of the scissors. Each wrapped piece of glass can then be placed back onto the mold.
7. Once all wrapped pieces fit onto the mold, they can be soldered.

Postoje dve tehnike izrade vitraža: sa profilima (tradicionalna) i sa trakama (tzv. Tiffany tehnika). Jedina razlika je u tome što se u prvom slučaju staklo umeće u žljebove unapred izrađenih profila a u drugom se ivice stakla oblažu trakom (appropriate width of copper foil) koja se zatim previja preko stakla sa obe strane. I u jednom i u drugom slučaju se obloženi delovi stakla spajaju lemljenjem.
