Enameling Help and Information

Thompson Enamels are lead-free glass products available in various particle sizes and formulated to fit a variety of metal and glass substrates. These products are described in terms of temperature and expansion to help you select a suitable enamel for your particular project. It is important to pre-test enamels prior to using: 1 printed or computer screen color charts do not always perfectly match the product they represent and 2 there may be slight variations in the character of any given enamel from batch to batch.

It is normally applied by sifting, but can also be mixed with water and inlayed or charged onto to the substrate surface. We suggest using a 40 mesh screen in our sifters to apply base coats of 80 mesh enamel to metal or glass substrates. These particles are ideal for bead making.

A variety of painting and liquid enamels are also available for specific substrates. All 80 mesh enamel products are numbered into a practical coded numbering system which indicates enamel type and color. This coding can be easily seen by examining our color charts in the printed catalog and online.

The thousands number indicates enamel type while the hundreds number indicates the color. The final two numbers indicate how light or dark that color is. For example, is an opaque pastel greenish blue for copper, and is a transparent dark blue for copper. Care should be taken not to ingest them. These products, however, can be used quite safely if you adhere to the following housekeeping and hygiene rules:. Rule 1. Keep products out of reach of children and pets. Rule 2. Keep your work area neat and clean.

Keep your clothing clean. Rule 3. Use your enamels in a well ventilated work area. Wear a protective dust mask if you are working with enamel powders for an extended period of time, especially when sifting enamels. Rule 4. Wash your hands prior to eating. Do not smoke or handle food when you are working with enamels. Thompson Enamel does not recommend the use of our enamels for food contact surfaces. Although they are very acid resistant and do not contain lead, their final food safe properties may depend on enamel application and firing.

Each such item made from them should be individually tested to determine whether or not it passes current F. You can see them on our web site here: Color charts. In general terms, vitreous enamel, porcelain enamel, copper enamel and jewelry enamel all refer to the same thing. Enamel is a glassy compound applied to and bonded by heat fusion to a metal surface; to a copper surface at degrees F. The most common glass is a fusion of silica, soda, lime, and a small amount of borax.

Though normally transparent, various amounts of opacity can be produced by adding or growing crystals within the glass structure. A wide range of colors are produced by incorporating certain elements, mostly transition metals.

The physical properties of glass can be controlled to permit bonding to most metals, for example, gold, platinum, silver, copper, steel, cast iron and titanium.

Enamel glass is crushed to a powder somewhat finer than granulated sugar and somewhat coarser than flour. This powder is applied, by one of several methods, to the metal or glass surface. Next the article is heated to to degrees F. For metal, in a preheated furnace the article may be fired from 1 to 5 minutes, depending on size or technique. The article is removed and allowed to cool to room temperature.

Subsequent coats, normally different colors are applied. Sometimes many firings are required to bring about the desired results. For fusing enamels to glass, the article is placed into a room temperature kiln and the heat is brought up according to the appropriate firing schedule to the maturation temperature, then brought down to an annealing temperature and held there for a period of time to relieve stresses in the glass, then brought back down to room temperature before removing the article.

We do not know when or where enameling originated. The earliest known enameled articles are six enameled gold rings discovered in a Mycenaean tomb at Kouklia, Cyprus. The rings date from the thirteenth century B. The Greeks were enameling gold jewelry as early as the 5th century B. Caesar found the Celtic inhabitants of Britain enameling in the 1st century B.

During the Byzantine era, 4th through 12th centuries, numerous enamel religious works were made. Fifteenth century artisans in Limoges, France perfected the use of enamels in a painting technique. The 17th, 18th, and 19th centuries and the early decades of the 20th, saw the production of a great volume of luxury and decorative enamels, made in many different centers. Starting early in the 19th century it was realized enamel could be used for utilitarian purposes.

First on pots and pans for cooking, then stoves, refrigerators, kitchen sinks, bath tubs, home laundry appliances, architectural panels, etc. Standard float window glass approx.. A sifter with a 40 mesh screen is used to apply 80 mesh base coats to metal or glass. A sifter with a mesh screen in the bottom of the cup is preferable when applying enamel through a stencil. When sifting enamel, sift around the outer edge of an object first, then move toward the center. The bottom of the sifter should be completely covered with enamel for a more uniform sift.

A holding agent such as Klyr-fire used in a sprayer that can create a fine mist will be required when coating a 3-dimensional object. It is best to apply alternating thin coats of spray, then enamel, then spray, then enamel, until an even coat has been achieved. If using a water based holding agent, the water must be dried before firing.

The trick to successful wet inlay wet charging or wet packing is to keep the enamel saturated with water. Too much water or too little water and the enamel is not manipulable.

Water may need to be added or wicked out with a paper towel while working. The work is dried before firing. If water is used in enamel applications as mentioned above, the metal first should be degreased.

The easiest method is to heat copper until it flashes with color annealing to green but not so long to create black copper oxide. Using Penny Bright is another method of degreasing the copper. It is important that the primary coat of enamel be as complete and as perfect as possible for the first firing.

Faults in the enamel are not easy to correct after the enamel has been fired in place. Unless fire-scale is meant to be part of the design, a sufficient amount of enamel should be applied so that burned out areas do not occur. However, thin coats are better than thick coats. More enamel may be reapplied if the coat is on the thin side, but too much enamel is a bigger problem. Too thick of an application may result in the enamel popping off.

As you continue to practice enameling, you will learn what is too little and what is too much. It is important to note that enamel, when properly applied and fired, does not flow out, but rather pulls in toward the greater mass unless gravity affects the movement.

If the enamel pulls away from the edge after firing, the cause could be too heavy enamel application. We suggest that both sides of the metal are enameled. Counter enamel is sold as a mixture of colors, however any enamel may be used as counter enamel.

Counter enamel is applied to reduce stress exerted on the enamel by the metal after the piece is cool or during cooling. Counter enamel literally equalizes or counters the pull of the metal on the enamel. The thickness of the metal and the thickness of the enamel are relative in this matter.

As the enamel thickness increases, the support thickness must also increase unless other structural considerations have been made in the metal.

Painting Enamels are much more finely ground. They may be combined with a painting medium and applied with a brush. Painting enamels are generally applied to a pre-fired enamel surface. Liquid Form, Water Base Enamels are formulated to be applied by spraying, dipping or pouring. These liquid enamels have clay in them. If applied with a brush, brush marks may occur. Liquid Form Brushable Enamels are formulated to be applied with a brush.

These enamels can be applied directly to metal or on top of other enamels. Some like to sift a little 80 mesh powder into the wet applied brushable enamel. When the brushable enamel is dried, the surface is quite handleable which allows one to then enamel both sides for the first firing.

This is especially helpful to reduce warping when enameling thinner gauges of copper. A slightly heavier coat of enamel may be applied to glass for solid colored areas. Stencils may be used and the enamel may also be wet with water as described above. The Glass Painting Powders are painting enamels recommended for use on glass. Enamels for metal are fired either in a pre-heated furnace kiln or a hand held torch. If firing in a furnace, the temperature should be between and degrees F.

This application is a division of application Ser. The present invention concerns firmly fixed decorative ceramic color layers applied to glass or glass ceramic substrates. Ceramic colors are often used to decorate glass and glass ceramics. They usually consist of one or several vitreous substances base enamel or vitrification and an admixture of one or several pigments coloring agents. Colored inorganic oxidic compounds, e. The pigments may thereby usually not be corroded or only slightly corroded by the vitrification dispersion coloring. Ceramic colors are usually manufactured by mixing frits quenched vitrifications with the inorganic pigments. The mixing may thereby already occur during the melting process of the vitrification fritting or before as well as during a subsequent pulverization process of the quenched glass mass. The ceramic colors ready for use are then provided in the form of powdery mixtures of coloring agents and glass.
