What are the size limitations for a section of leaded glass?
Although we have restored panels as large as 20 sq-ft, we recommend that a large area be divided by framework into panels of about 10 sq-ft or less, in any combination of length to width ratio. Large areas are subdivided into smaller panels by some type of mullions or framework. If steel T-bar is used as the framework, it usually disappears visually into the design. this is the type of framework that has been used for centuries in cathedrals.
