Copper foil vs. lead came technique

When it comes to assembling the pieces of stained glass, two main techniques are commonly used: the copper foil technique and the lead came technique. The copper foil technique involves wrapping the edges of each glass piece with a thin strip of copper foil, which is then soldered together. This technique allows for more intricate and detailed designs. On the other hand, the lead came technique uses strips of lead, known as came, to hold the glass pieces together. This technique is more suitable for larger, more traditional designs.

Soldering and joining glass pieces

Soldering is the process of joining the copper foil or lead came together, creating a strong and durable bond. It involves melting solder, a metal alloy, using a soldering iron or soldering gun. Soldering not only binds the pieces of glass together but also adds strength and stability to the finished stained glass piece. It is important to ensure the correct temperature and technique to achieve smooth and secure soldered joints.

Applying patina and finishing touches

Once the glass pieces are joined together, the next step is to apply patina to achieve the desired color and finish. Patina is a chemical solution that can be applied to the soldered joints to darken and add an aged appearance. Care must be taken to evenly apply the patina and remove any excess. After the patina has been applied, the stained glass piece goes through a final cleaning and polishing process to enhance its overall appearance. Finally, reinforcing hooks or hangers can be added to ensure the piece can be safely displayed or installed.
