Tiffany Panel from the Richard Mellon Home.
1908
I am a fan of the Morse Museum. The Morse is in the college town of Winter Park, Fl. They have an extensive collection of Tiffany artwork. This is part of the collection. The panel was originally the center piece of a 10-panel window designed for the landing of a massive marble staircase in the Pittsburg home Of Richard B. Mellon. The panel was divided up when the 60-room house was demolished in 1940.
The piece is done totally in opalescent glass. It must have been a remarkable sight at the top of the equally remarkable marble staircase.
Tips from the Glass Academy: Lead Came or Copper Foil
The basic thing to remember here is that Lead Came stretches. That really is the base fact in deciding when to use what.
Use Foil:
1. Lamp Shades should always be done in foil. All those beautiful Tiffany Studio lamp shades were done with foil. He was the master so just do what he did! If you make a lamp with lead, over time it will collapse unless you reinforce the lead. That just adds to the work and to the weight.
2. Lead is heavy. If weight is an issue, use foil.
3. Items like jewelry boxes should be foiled. It is way easier to deal with the angles with foil.
4. When you have little pieces that will be lost in the lead, use foil. You can even mix. A lead came panel can have a section that is foiled. Most little projects are done with foil.
Use Lead:
1. When you are making a project that will be in the weather, use came. Came can be puttied/cemented to make it more weather tight.
2. Geometrical patterns lend themselves nicely to lead came.
3. Really large piece, like Church window are nice with lead came because of the size. The boldness of the came fits the size. To get the bold width with foil would be difficult and probably irregular. Came stays nice and uniform.

4. Little suncatchers are sometimes made with
hobby came, which is a tiny came. Simple ones. It is fast.
4. Even though lead stretches, it takes time. Most Church windows do not need to be releaded for 100 years. When you see that a window is budging at the bottom, you can usually bet that it is old, and the lead has expanded and contracted over time and the weight of the glass has been pushing down during this unseen activity. If you used foil on a window that is exposed to weather and weight, you may see stress cracks in the glass.
Criteria | Copper Foil | Lead Came |
---|---|---|
Design Complexity | Intricate, detailed patterns | Simpler, larger geometric designs |
Size of Project | Small to medium pieces | Larger panels or structural pieces |
Structural Strength | Lightweight, non-load-bearing items | Heavier, load-bearing installations |
Style Preference | Thin solder lines, modern styles | Bold lines, traditional styles |
Tips from the Glass Academy: Beadmaking
Though not really new, because it has been around since the 19th century, bead making is gaining momentum. One way to get into it is to buy a Hot Head torch like you see in the pictures below. This is easily something you can do at home. That is just propone you see attached.

If you really want to dive in, you can buy a bench burner which needs to be hooked up to gas and oxygen. The one below is an Alpha. You can use a 3-gallon propane to run this and a oxygen generator.

Luminescent Glass & Iridescent Glass in Fusing
Luminescent glass is different than iridescent glass. It is low-fire—not high-fire like iridescent—and is intended for reverse fusing.
What is reverse fusing? Reverse fusing means placing your piece face down on the kiln shelf and building backwards, fire-coated side down. If you are firing on a textured mold, place a piece of Thin Fire between your boron-treated mold and the glass. If you fire your piece with the coated side up or cover it with another piece of glass or you will lose the coating. If you are slumping and do not go over 1,200 degrees, you can place the luminescent side up and not lose the coating. Luminescent glass is food-safe and has been tested by the U.S. Food and Drug Administration. However, please note that once the piece has been fired in your kiln, it is no longer a Wissmach product; it is your product. If you have been firing glass that could leave lead or cadmium traces in your kiln, that could get on the product, which would render it unsafe for serving food or beverages.

Iridescent glass is made by Oceanside, Bullseye and Youghiogheny. Also Wissmach non fusible. When firing it can be placed up or down. This info from Oceanside.
Iridescent glasses have a micro-thin layer of metallic crystal creating a reflective surface that shimmers in rainbow, silver, or gold tones. Because of its metallic nature, the coating has specific characteristics that are important to understand as you plan fused glass projects.
The metallic coating doesn’t melt so it resists bonding:
If you were to try to fuse two iridized surfaces facing together, they will not bond well, if at all.
When stacking a design on top of an Iridized surface, you may get more of a tack-fused look than you intend. Use this to your advantage to create very dimensional work or adjust your schedule.
To fully clear cap an Iridescent glass, make sure your piece of clear is slightly larger (between 1/8" and 1/4" on all sides) so that it has enough area to bond with the edges of the glass below.
The metallic coating doesn’t stretch:
This is why a crackling effect can be seen when Iridescent glasses are allowed to spread — especially when the irid surface is on top, face-up. Enjoy the look—alternately, dam pieces or construct them using a circular design (where the glass tends to draw inward when full-fused) to minimize the effect. Clear capping produces more of a pinching or crinkling look as the clear presses into the coated surface below.

The same coating is more dramatic on darker glasses:
The rainbow iridescence on Clear or White is much more subtle and delicate than on darker colors or Black, which is the most dramatic.
Firing for Different Effects:
Irid side down: in this example, the iridescent surface of the glass is placed face down on the kiln shelf paper, with a piece of clear on top. This look can make a lovely matte finish for either the top or bottom of a piece.
Irid side up: in this example, the iridescent surface of the glass is placed face up on top of a piece of clear. This gives the most opportunity for glass to spread and crackle.
Irid side up and capped with clear: in this example, the iridescent surface of the glass is placed face-up and capped with a slightly larger piece of clear glass on top.
Using Clear Textured Iridescent Glasses:
Place the texture side down onto a darker base glass. Although the texture will flatten using a full fuse, the irid design from the texture will still be visible with interesting distortions from the texture. Do small test fires to know.
In smaller pieces of Iridescent Clear or other light colors, it can be difficult to tell which side has the coating. Simply scratch both sides with your fingernail--the irid surface will grip more than the smooth side.

Tips from Janet: Know Your Tools—Pliers
I just went to the retail display where we keep pliers. There were 7 different ones. So many pliers—so many uses! Or just a little difference, like the width of the jaws that someone might prefer.
Your first plier should be a breaker/grozer. Double duty! Their primary function is to grasp the glass securely on one side of a score when breaking it apart. Both jaws have serrated teeth to assist in their second duty, grozing.
Second pair you should buy is probably a running plier. This plier is designed to apply pressure under a score causing the break to follow (run) along the score line. Metal ones have the advantage of being adjustable for the thickness of the glass you are working with. Plastic also available.
Breakers. These have straight jaws and are designed to grasps the glass to assist in breaking long thin pieces of glass. The wide jaws meet only at the tip and not serrated.

Soldering Iron Temperature control
Plugging a soldering iron into a rheostat (or temperature controller) does NOT reduce the temperature. It reduces the amount of electricity coming in but doesn't change the temperature the iron will heat up to. It will just take longer to heat up. It's the same as the tap on your sink. Turning the tap down will make the water come in slower, but the water will still fill up your sink. It'll just take longer to fill up.
1. Basic Concept of a Rheostat:
- A rheostat is a variable resistor. It adjusts the resistance in a circuit, which in turn controls the current flow.
- By increasing the resistance, the current flowing through the circuit decreases, which reduces the power delivered to the soldering iron.
- Conversely, reducing the resistance increases the current flow, increasing the power to the soldering iron and therefore the temperature.
2. Operation with a Soldering Iron:
- Input Voltage: When a soldering iron is plugged into the rheostat, the device controls how much of the mains voltage reaches the iron.
-
Power Control: Turning the rheostat's dial changes its resistance, altering the amount of current flowing through to the soldering iron’s heating element.
- Higher Resistance = Less Power = Lower Temperature.
- Lower Resistance = More Power = Higher Temperature.
The most popular iron right now is Hakko Fx601. It comes with an internal thermostat. A thermostat automatically maintains a set temperature. That makes it way easier to learn to solder with a nice line. If you don't have to constantly adjust for your temperature you will have an easier time.

Not everyone wants to pay over $100 for an iron when they are first learning. This person can buy an inexpensive 100-watt iron and hook it up to a rheostat and find out if they like the hobby.

Glass No Longer Available.
The tough economy of 2011 and 2012 caused some glass manufacturing to cease. The GNA (German New Antique) factory has now been closed for some time. At first it was thought that it would be retooled and reopened. That has not happened. As distributors run out, they will be gone. Colored Glue Chip has also disappeared. We can still get clear but that is all. Oceanside does manufacture a line of Artique glass which is quite beautiful and are great substitute for GNA.
The green is glue chip, the blue is GNA and the purple is Oceanside's grape artique.
Wasser has also disappeared. This was a less commonly used glass, but some have made beautiful, fused jewelry and plates with it. It was a thin 90 Coe glass. We also had a customer who made doll house items with this glass.
Kokomo Opalescent Glass had a series of difficult situations during and after the pandemic. They are manufacturing glass,` but it continues to be very scarce and many of the numbers have not been seen in a number of years.
This is Camouflage, Hawaiian Sunset and Dragons' Breath which are hopefully going to be available soon.
