Copper Foil & Soldering Tech vs Alternatives: My Honest Hands-On Comparison
As a stained glass artisan and restorationist, I often find myself in a constant exploration of materials and techniques that can elevate my craft. In my workshop, where the light streams through colorful panes of glass, I often ponder the age-old debate: copper foil and soldering technology versus alternative methods like lead came and epoxy. I’ve spent years honing my skills, and I want to share my honest hands-on comparison of these materials and techniques, so you can make informed choices for your own projects.
Understanding the Basics
Before working through my comparisons, let’s clarify what we’re discussing. Copper foil and soldering is a method pioneered by Louis Comfort Tiffany in the late 19th century. This technique uses thin strips of copper foil applied to the edges of glass pieces and is then soldered together. Alternatively, the lead came method involves using lead channels to hold the glass pieces together, often resulting in a sturdier structure.
The Pros and Cons
Here, I’ve broken down the advantages and disadvantages of each method based on my experience.

My Hands-On Experience
Copper Foil: A Love Affair
When I first started with copper foil, I was captivated by its versatility. The ability to work on intricate designs without the constraints of lead channels allowed me to express my creativity fully. I remember my early trials, where I struggled to keep my soldering lines smooth. After countless hours of practice, I found that using a fine-tip soldering iron (I use a 25-watt iron) made a significant difference, allowing for more precision.
I typically use 7/32” copper foil, which balances strength and flexibility. A roll costs around $5 at local craft stores or online. The key is to apply the foil evenly and burnish it down securely to the glass. The results are stunning, with crisp seams that catch the light beautifully.
The Strength of Lead Came
On the other hand, lead came has its undeniable advantages. I recently worked on a large window restoration project that required the strength of lead. The process was more straightforward: cutting the lead came to size and fitting it around each piece of glass. I found it to be a faster method for assembling larger panels, and the structural integrity was impressive.
However, the heaviness of lead can be a drawback, especially for hanging pieces or installations that need to be transported. When working with lead, I use a traditional soldering iron and a lead-safe flux to ensure a clean, safe workspace. A typical cost for lead came is about $1.50 per foot, which can add up depending on the size of your project.
The Quick Fix of Epoxy
I’ve also experimented with epoxy, especially for smaller, simpler projects. While it does not have the same aesthetic appeal as solder seams, it’s a fantastic option for beginners. I found a high-strength epoxy that cures in about 5 minutes for around $12. It’s easy to use, and I often recommend it for small sun-catchers or repairs on stained glass.
However, my experience with epoxy taught me that it may not provide the longevity I wanted. Over time, I noticed some pieces starting to separate, especially in areas exposed to sunlight.
💡 Evelyn Thorne's Rule of Thumb:
Always consider the final application of your piece. If it’s something you want to last for decades, go for copper foil or lead came. For quicker projects or temporary displays, epoxy can be a lifesaver.
