Proper handling of materials is important to prevent breakage and injury. Glass pieces should be handled with care, avoiding unnecessary pressure or stress. When cutting glass, it is important to use the correct tools and techniques to minimize the risk of chipping or shattering. Adequate storage and labeling of materials also help prevent accidents and ensure that materials are easily accessible and protected from damage.

The Glass Cutting Process

Scoring the Glass

The glass cutting process begins with scoring the glass. A glass cutter is used to create a shallow score or line on the surface of the glass, following the design template. The score weakens the glass along the desired cutting line.

Breaking the Glass

Once the glass has been scored, it can be broken along the scored line. Grozing pliers are used to grip the glass along the score and apply gentle pressure, causing the glass to break cleanly. Careful control and precision are necessary to ensure accurate and clean breaks.

Refining Edges

After breaking the glass, the rough edges are refined using a glass grinder or sandpaper. The grinder helps to remove any sharp edges and smooth the surface of the glass, ensuring that each piece fits together seamlessly during the assembly process. The refinement of edges is a delicate and time-consuming process that requires patience and attention to detail.

The Foiling Process

Types of Foil

The foiling process involves wrapping each piece of glass with a thin strip of copper foil. Copper foil is used because it is flexible and easily adheres to the glass surface. There are different types of foil available, ranging in thickness and adhesive strength. The choice of foil may vary depending on the size and complexity of the stained glass panel.

Applying the Foil

To apply the foil, the glass piece is carefully aligned with the edge of the copper foil strip. The foil is then wrapped around the edges of the glass, creating a tight and secure bond. The excess foil is folded or trimmed to ensure a neat and even appearance. Adhesive-backed foil can also be used, eliminating the need for additional adhesive during the foiling process.

Methods for Foiling Curves and Angles

Foiling curved or angled glass pieces requires additional techniques to ensure proper adhesion and a smooth finish. For curved pieces, the foil is stretched or crimped to accommodate the curvature of the glass. Angled pieces may require the use of pattern shears to create precise cuts in the foil, allowing for a clean and seamless fit. These specialized techniques help maintain the integrity of the foiled pieces during the assembly process.

Assembly of Stained Glass

Positioning the Pieces

The assembly of stained glass involves fitting the foiled glass pieces together within the lead came framework.
