1. What is leaded art glass?
Leaded glass is the traditional stained glass used in churches for over 1000 years. It is made from pieces of colored glass about 1/8″ thick, held together with lead channels soldered at every joint.
2. What are applications for leaded glass?
At Dazzle Glazz Studio, we focus on windows and panels for architectural applications like churches, chapels and public spaces like train stations, hotels & restaurants in our Liturgical & Architectural division.
Leaded glass is also widely used in homes in beveled glass entry doors, sidelights, transoms, windows, interior doors and room dividers, cabinets, furniture, and fireplace screens, autonomous panels and “sun-catchers.”
The Dazzle Glazz Studio – Residential Division focuses on these types of art glass.
3. How are the pieces of glass held together?
The colored glass is cut to shape based on the approved design pattern. Lead channels of various widths are molded to the glass edges and soldered at each joint to hold the pieces of glass together. Putty is brushed under the lead edges to seal the glass panel and to convert it to a single rigid panel.
4. How long has this kind of glass been around?
Artifacts of stained glass from an Abby in Germany date from the 9th or 10th century. Although the fabrication tools have improved, the basic process is unchanged from the Middle Ages.
5. What kind of longevity does it have?
Windows exist in European cathedrals which are hundreds of years old. Lead can become weak over time, and typically a window will have to be re-leaded sometime between about 75 and 150 years.
6. How does this leaded glass compare in price to other forms of art glass?
Leaded glass represents a substantial investment in art because of the large labor component in its fabrication. Other types of art glass might be fabricated at a lower cost for similar designs. However, leaded glass is often favored because it is the most traditional type of art glass.
7. What factors determine the price of leaded glass?
The fabrication cost is primarily a function of size and complexity of the piece. The more complex the image, the greater is the cost per square foot because of the labor involved. The type of glass used is also a factor. (We recommend antique, mouth blown glass for its beauty). Additional value components which can be handled by Dazzle Glazz Studio or by others are design, framing and installation.
8. Where will the leaded glass be fabricated?
Dazzle Glazz Studio is located in Baton Rouge, Louisiana. From here we do our faceted and leaded glass design, fabrication and project coordination. On a larger project, we may involve one of our partners in assisting with the fabrication.
9. 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 visually disappears into the design.
10. How is leaded glass installed?
Either just like normal clear glass, or on the interior of clear glass by use of a pair of “glass stops” (moldings) that create a space between the clear glass and the leaded glass.
11. Are there special framing systems required?
No. Any kind of wooden, aluminum or other window, storefront, and ecclesiastical window system may be used with leaded glass.
12. What is the thickness of the glass?
Most commonly the glass is 1/8″ to 3/16″ in thickness and secured into metal channels that are 1/4″ to 3/8″ thick.
13. What are the design possibilities?
We can do all types of designs from representational images with painted features like hands and faces to very abstract designs of just motion and color. Our studio engages multiple artists, each with a unique style of his/her own. On many projects we submit designs from several artists to insure that we meet the client’s needs.
14. What are the color possibilities?
We use glass from dozens of vendors with thousands of colors and shades so there is no practical color limitation. The design is limited by the strength and cut-ability of glass. (Where extreme shapes are required, we recommend our inlaid glass where there are practically no limitations).
The lead is dark gray and will always appear as a dark shadow on the inside because it blocks the light. We use lead widths from 1/8 inch wide up to 2 inches wide. Large panels will require reinforcement with steel bars to guarantee the window strength for decades. We typically bend our bars to follow the design lines and thereby render them invisible.
