Lewis lead refers to a specific type of lead used in the construction or repair of stained glass windows. It is a structural element that assists in supporting and reinforcing the window panel, particularly in larger or more complex designs.
The term "lewis lead" is derived from the name of a tool called a lewis, which is used in masonry to lift and position heavy stones. In the context of stained glass, lewis lead serves a similar purpose. It is a thick, rigid lead channel that runs along the edges of glass pieces within the panel, providing stability and strength.
Typically, lewis lead is used in the outer perimeter of a stained glass window, forming a border around the individual glass pieces. This lead channel is wider and deeper than the other pieces of lead used in the panel, allowing for greater structural support. It often has a distinctive "U" shape, with a flat base and tall flanges on either side.
One of the key functions of lewis lead is to hold the glass pieces securely in place, preventing movement or shifting. It helps distribute the weight of the glass evenly, reducing stress on individual pieces. Additionally, lewis lead can also be used to create decorative effects by incorporating design elements or patterns within the channel.
In summary, lewis lead is a thick and rigid lead channel used in stained glass windows to reinforce the structure and support the glass pieces. Its purpose is to provide stability, distribute weight evenly, and enhance the aesthetic appeal of the window.
