ART OF STAINED GLASS
HOW TO PAINT GLASS

Enamel
Enamels become transparent after firing. They are said not to be as permanent as tracing black and mattes, and are historically used sparingly. However, they are so cheerfully pretty, I can't help but look forward to this step. Enamels fire at 1050-1080F - under my conditions, the enamels don't fully develop their transparency with a 1050F, 5 minute soak, and I found that 1080F for 15 minutes worked more reliably. To get a vivid orange, I like to overlay some enamel (Carmine 2777) over the silver stain. It is very important to note that even a bit of carmine will totally obscure the silver stain beneath it, and the carmine enamel must be used sparingly when trying to create orange.

Special note: enamels are NOT blendable colors, some may react unattractively with each other if touching when un-fired. Once a color is fired, another color can be superimposed safely.

For this project, I will create a matte of carmine, with more intense areas for the flowers than for the butterly wings.

Now I brush off the excess powderd enamal after the matte overlay has dried:

After the last firing, the enamels once heated to the right temperature (I like the upper range, 1080F) become translucent. The painting now needs to be set a leaded frame of glass and zinc.
