Bulk Mosaic Glass Lamps for Hospitality & Contract

Most workshops set a starting MOQ in the range of roughly 50–100 pieces for stock designs, because every shade is hand-cut, foiled or leaded, soldered, and then fitted to a base one at a time. MOQ climbs sharply for custom patterns since a new template must be drawn, glass colorways pulled from sheet stock, and the shade prototyped before production can start. Simpler globe shapes with fewer tesserae per panel keep MOQ lower than multi-panel or large floor-lamp silhouettes that demand many more soldering hours per unit.

Hold the shade up to a strong light and check for hairline cracks, chipped glass edges, and visible gaps where lead came or copper-foil joints should sit flush; run a finger along seams to feel sharp solder protrusions or drips. Inspect solder lines for cold joints, oxidation, or patchy coverage, and confirm the shade sits level on the base with the bulb socket perfectly centered. Also verify the cord passes through a grommet or socket assembly rather than directly through glass, and that the switch and plug are rated for the destination market.

Lead came uses H-shaped lead strips that grip each glass edge and are soldered at the joints, giving the traditional heavy, sculptural Turkish look with clearly visible dark seams between every tessera. Copper foil (the Tiffany method) wraps each piece individually and is soldered on both sides, which allows tighter curves and crisper geometric patterns but adds labor per piece. For hospitality and residential use both are durable; lead came flexes slightly on impact, while copper foil gives finer detail and a tighter pattern.

Yes—buyers can specify globe, cylindrical, drum, or multi-shade silhouettes, choose glass colors from the workshop's sheet stock, and supply a pattern or modify a stock design. Custom work typically requires a higher MOQ than stock, a 4–6 week sampling and prototype phase to draw the template and cut the first shade, and roughly 8–14 weeks of production after sample approval. Expect a one-off template or mold fee for fully bespoke shapes, and confirm up front whether the resin, ceramic, or metal base is included in the customization scope.

For the EU ask for a CE Declaration of Conformity covering the Low Voltage Directive and EMC Directive, plus a RoHS test report confirming restricted-substance limits in the glass, lead came or solder, and base materials. For the US and Canada require UL or ETL listing on the complete lamp—UL 153 covers portable luminaires—and confirm the cord set is listed or recognized rather than generic. The craft's traditional center is the Cappadocia/Avanos region, so if your retail customers ask about provenance, request a signed origin statement and any regional authenticity paperwork the maker can supply.
