Properties of black cobalt coatings

The optical properties of electrolytic black cobalt coatings with different film thicknesses are reviewed.

Although the intrinsic selectivity of black cobalt is only moderate, efficient selective surfaces can be prepared on highly infrared reflecting metals like smooth copper. The optical and structural investigations show that the porous material consists of a granular distribution of a cobalt-rich phase, which causes a significant infrared absorption.

Due to this, the angular dependence of the thermal emission is strongly dependent on film thickness. The influence of different annealing steps on the film properties is discussed.

It is shown that black cobalt can be used in high-temperature designs of flat plate evacuated tubular collectors, provided the annealing process is performed under inert conditions. If the coating is used in air, degradation may occur due to oxidation of cobalt metal above 200°C.

Chemical properties of porcelain enamel powder

1) porcelain enamel powder often is applied as a paste, and may be transparent or opaque when fired; vitreous porcelain enamel powder can be applied to most metals. It has many excellent properties: it is smooth, hard, chemically resistant, durable, can assume brilliant, long-lasting colors, and cannot burn. Its disadvantages are its tendency to crack or shatter when the substrate is stressed or bent. Its durability has found it many functional applications: early 20th century advertising signs, interior oven walls, cooking pots, exterior walls of kitchen appliances, cast iron bathtubs, farm storage silos, and processing equipment such as chemical reactors and pharmaceutical chemical process tanks. Commercial structures such as gas stations, bus stations and even Lustron Houses had walls, ceilings and structural elements made of porcelain enamel powderl steel.

2) Color in porcelain enamel powder is obtained by the addition of various minerals, often metal oxides cobalt, praseodymium, iron, or neodymium. The last creates delicate shades ranging from pure violet through wine-red and warm gray. Porcelain enamel powder can be either transparent, opaque or opalescent (translucent), which is a variety that gains a milky opacity the longer it is fired. Different porcelain enamel powder colors cannot be mixed to make a new color, in the manner of paint. This produces tiny specks of both colors; although the eye can be tricked by grinding colors together to an extremely fine, flour-like, powder.

Vitreous enamel information

You will recognise vitreous enamel as the material used to produce the now highly collectable advertising signs produced during the early 20th Century. The ‘Hovis’ and ‘Virol’ signs were part of the everyday street scene. Your cooker will almost certainly have a vitreous enamelled oven and the higher quality cookers will use it on the outer parts. Your cast iron or steel bath will have been vitreous enamelled. Less obvious are the storage silos on farms, usually blue or green; they tower over the surrounding countryside. Carl Faberge used enamel for his unique eggs and jewellery and the Battersea enamellers are famous for their copper enamelled boxes. These are just two of the better known groups of highly skilled artists who used this very special material.

The word enamel comes from the High German word ‘smelzan’ and later from the Old French ‘esmail’. The Collins English Dictionary defines enamel as ‘a coloured glassy substance, transparent or opaque, fused to the surface of articles made of metal, glass etc. for ornament or protection’. Vitreous enamel is specifically on a metal base. It is thus defined as a vitreous, glass like coating fused on to a metallic base. In American English it is referred to as Porcelain Enamel.

It should not be confused with paint, which is sometimes called ‘enamel’. Paints cannot be enamel. They do not have the hardness, heat resistance and colour stability that is only available with real vitreous enamel. Beware of companies or products implying the use of enamel. Check their credentials and warranties.

The glass will be applied to the metal by a various methods either as a powder or mixed with water. This is followed by heating in a furnace to a temperature usually between 750 and 850 degrees Celsius. This ‘firing’ process gives vitreous enamel its unique combination of properties.

The smooth glass-like surface is hard; it is scratch, chemical and fire resistant. It is easy to clean and hygienic.

Vitreous enamel can be applied to most metals. For jewellery and decorative items it is often applied to gold, silver, copper and bronze. For the more common uses, it is applied to steel or cast iron. There are some specialised uses on stainless steel and aluminium.

The durability of the early advertising signs, still showing the brilliance of the original colours after a hundred years, is one of the best examples of the long-term colour stability of vitreous enamel. Compare them to signs, for example road signs, produced in less durable materials which fade and become shabby. Some of the early vitreous enamelled relics date back to the 13th Century BC and the colours are still as vibrant as the day they were produced (see our page on Enamelling History). If you want something where the colour will never fade – use vitreous enamel.

Following the disastrous King’s Cross fire, where combustible materials underground were the major cause, the specification of vitreous enamel for both decorative and functional parts in underground applications is now universal. It cannot burn, in contrast to paints and plastics. The famous London Underground station signs and maps are instantly recognisable uses of this unique product.

A short history of jewellery enamelling process

The art of enamelling jewellery is an ancient one. The earliest archaeological finds from ancient Greece date from 1600 BC. Enamelling process on metal is very hot work. The process requires temperatures in excess of 500 degrees centigrade which melts the enamel creating an impermeable bond, a smooth surface and brilliant colours.

For centuries enamelling process would be used primarily for the creation of religious objects and most of the oldest artefacts involved enamelling process on gold (Cloisonné technique). The museum of Cyprus in Nicosia houses a golden sceptre (1100 BC) which was found near Episkopi and its spherical top is enamelled in white, lilac and green.

From the 5th century BC the La Tene culture of Western Europe produced enamel objects on bronze usually of a bright red colour. The Greek writer Philostratus of Lemnos witnessed that the northern Barbarians of the ocean regions applied colours on hot bronze (Champlevé technique).

The early middle ages from the 5th century AD onwards saw a new impulse of Celtic-roman art in what is today known as Ireland, England and Scotland. One of the most beautiful and well known pieces to be created in this period in Ireland is the Ardagh chalice. The chalice is elaborately decorated with layers of gold thread one on top of the other and at intervals are set cloisonné enamel bosses of blue and red.

Another very important and famous piece created in the period 400 AD to 800 AD is the Iron Crown. Originating in the time of Constantine (350 AD) it was Charlemagne who restored this crown of gold and added 21 of the 24 enamel plates and wore the crown at his coronation in 800 AD. Since then the Iron crown has been worn by 32 kings and emperors including Napoleon Bonaparte on the 2nd of December 1804. Today the crown is in the possession of the Monza Cathedral in Northern Italy.

During the late Middle Ages (1100 to 1500 AD) schools dedicated to Cloisonné enamelling process sprung up in Liège, Cologne, Limoges and Silos. New Techniques were perfected such as “Translucent relief” and “Bas-relief”. Bas-relief is the filling of engraving or chisel marks with enamel.

The Renaissance period (15th-16th Century) saw the beginning of enamel painting and the first work considered to be a true painted enamel is by Nardon Penicaud (1470-1542) in 1503. Leonardo Da Vinci wrote in his “treatise on Painting” – “A painting on thick copper, covered with enamel on which it is painted with enamel colours and then put into the furnace again and fired, far exceeds sculpture in durability”.

The Grisaille (cameo) technique appears in 1530 and consists of firing dark enamel on a copper surface covered with white enamel figures completed with bas-relief firings. It is well suited to miniatures and snuff boxes and cameo pendants were popular at the time. The Guilloche technique is introduced where gold or silver sheet is covered by fired layers of transparent enamel. Faberge would later use this technique so famously at the end of the 19th century and early 20th century.

The art deco period from 1920 to 1930 would see enamelling process make a resurgence in many different art forms. Enamel art jugs created by Faure Atelier are highly sought after today.

Here we feel we are continuing this 3,500 year old art of enamelling process and producing our own unique style of jewellery which we hope will be enjoyed by people long after we have moved on too.

Vitreous enamel

Vitreous enamel, also called porcelain enamel, is a material made by fusing powdered glass to a substrate by firing, usually between 750 and 850 °C (1,380 and 1,560 °F). The powder melts, flows, and then hardens to a smooth, durable vitreous coating. The word comes from the Latin vitreum, meaning “glassy”.

Enamel can be used on metal, glass, ceramics, stone, or any material that will withstand the fusing temperature. In technical terms fired enamelware is an integrated layered composite of glass and another material (or more glass). The term “enamel” is most often restricted to work on metal, which is the subject of this article. Enamelled glass is also called “painted”, and overglaze decoration to pottery is often called enamelling.

Enamelling is an old and widely adopted technology, for most of its history mainly used in jewelry and decorative art. Since the 19th century, enamels have also been applied to many consumer objects, such as some cooking vessels, steel sinks, enamel bathtubs, and stone countertops. It has also been used on some appliances, such as dishwashers, laundry machines, and refrigerators, and on marker boards and signage.

The term “enamel” has also sometimes been applied to industrial materials other than vitreous enamel, such as “enamel” paint and the polymers coating “enamelled” wire.

The word enamel comes from the Old High German word smelzan (to smelt) via the Old French esmail, or from a Latin word smaltum, first found in a 9th-century life of Leo IV. Used as a noun, “an enamel” is usually a small decorative object coated with enamel. “Enamelled” and “enamelling” are the preferred spellings in British English, while “enameled” and “enameling” are preferred in American English.
