| “Over-fired Cuff”' by Emilie Shapiro (vitreous enamel on free-form copper) |
Enamel is a decorative glass craft with a history that dates back as far as 3150 BC in Ancient Egypt. I’ve been taking a basic but very intensive enamel class right here in Brooklyn at
Liloveve Studio with instructor
Emilie Shapiro, a contemporary jewelry designer.

| Sgraffito is a decorative a technique of scratching a wet top layer to create linear designs. |
Powdered glass is fused at temperatures of 1380 to 1560 °F to create a hard porcelain-like finish. It’s used on decorative surfaces and jewelry as well as on the enamel we use as cookware. Powdered glass comes in a wide range of opaque and transparent colors, but a true red is hard to obtain.
It helps to have some practical knowledge of metalwork. In this first series of classes, Emilie helped us master the skills and techniques of firing colored glass onto copper by dry-sifting, and wet-packing.
We had our hands full applying layer upon layer yo build a solid opaque surface. Our first project involved
sgraffito, an Italian technique in which a design is scratched into a wet layer of enamel to reveal a contrasting color of finished enamel below. It works best with opaque colors.
A copper surface is first cleaned well with denatured alcohol, then buffed dry and treated with Klyr-fire, a cellulose adhesive. Traces of hand grease and impurities affect how well the color covers as it is heated. In this lesson powdered glass is applied by sifting evenly onto the treated surface. Multiple colors can be applied to created an organic gradation but it's best not to blend a new color with this method.
Of course my favorite part of this class was Torch Firing with an acetylene torch.
Isn’t that every boy’s dream? This is the most practical way to learn how different materials react to high concentrated heat (“high fire”). You literally can watch metal and glass melt and oxidize. If you're not careful you might melt your project to the trivet —
I learned that the hard way.
Work carefully and quickly. As you wait for the copper to turn a bright shade of orange you must also watch the texture of the glass as it fuses. The powdered glass first takes on the texture of granulated sugar as you move the torch around from below. It’s finished when it takes on orange peel texture. When glass is heated to the point of burning it’s called “over-firing.” This effect is similar to raku pottery.
The finished enamel is moved to a clay surface to cool, then is
pickled in a low acid bath. More layers can be applied to create different effects as you can see from the examples we made in this class.
Copper is a great conductor of heat, it also has a lower melting point than the steel trivet used for support. Other types of metal for enamelware are fine gold, and sterling silver.
In this studio class we gained a practical knowledge of all tool sand materials for working with enamel. This class has been nothing less than fascinating, but there’s still so much more to learn. Perfecting these techniques lead us to the making
cloisonné jewelry. Cloisonné is a Far Eastern technique refined by the French. The word “cloison” is French for partition. This enamel technique involves inlaying different colors into separate compartments made from thin strips of wire. It resembles a painting made from jewels.

I was very flattered — of all the things that a very hip tween wanted for her birthday, my friend Dawn’s daughter requested my Zuki cell phone caddy. Everything is just late, and as of late I’ve been busy developing Zuki’s big brother, the Wombat® iPad Tech Pillow. This Zuki is a vast improvement over the first one. It’s now 200% cuter. In other news, Tom and I have are close to getting the Wombat® into production and out to market. Cheers to TomTone Industries!
