Cames

Cames are metal strips used to join pieces of glass in stained glass windows and related works. They provide the structural framework and the characteristic lines that define the finished piece. Traditionally crafted from lead, cames can also be made from zinc or other metals in modern practice, offering different properties and durability.

Lead came is the traditional choice, valued for its softness and excellent ability to be bent to fit irregular glass shapes. This makes it well suited to decorative, curved, and detailed panels. Zinc came offers greater rigidity, weather resistance, and lighter weight, making it popular for larger or exterior installations. In contemporary work, cames are selected for width, thickness, and profile to match glass thickness and design requirements; flat and channel variants are used in different applications, including mosaics.

The construction process involves cutting glass pieces to fit within the channels of the came, assembling them piece by piece, and joining the intersections with solder (often lead-tin solder). After assembly, the gaps between came and glass are sealed with cement or putty to waterproof and stabilize the panel. The completed panel is then cleaned and, if desired, finished with a patina or varnish to control corrosion and appearance.

History and use: the lead came technique has been fundamental to stained glass since medieval times, featured in many church windows and decorative panels. It remains a core method in traditional stained glass, while zinc came and alternative techniques have expanded options for modern architecture and large-scale works.

Maintenance and safety: cames can deteriorate over time due to weather exposure, corrosion, or mechanical stress, requiring repair or replacement. Lead came poses health concerns if dust is inhaled or ingested, so handling should follow appropriate safety practices. Regular inspection, gentle cleaning, and professional restoration are advised for aging installations.
