Weighing In

 

QUESTION: Ever since I was a little boy, I’ve had a fascination with scales. I love weighing things. Now that I’m older, that fascination has turned to a passion for collecting old scales. Currently, I have about 10 scales of varying ages that I acquired from various sources over the years. I’d really like to expand my collection, but I don’t know much about the history of scales and don’t really know where to start. Can you help me?

ANSWER: You have a very unique interest. Scales and other weighing devices are forms of scientific instruments. Scales have played an important role in economies around the world throughout history. 

The earliest known weighing scales date back to ancient Egypt and Rome. Some of the earliest examples of weight measurement consisted of a simple rod suspended by a string in the middle. The user attached a pan to each end. In one pan, he placed  the item, such as a sack of gold coins, to be weighed and in the other stones representing a known weight until he balanced the rod. By calculating the total of the known weights, the user could determine the weight of the object in the other pan.

The ancient Egyptians used balance scales for trade and commerce Scales were also important religious symbols. The primary role of the Egyptian goddess of justice, called Maat, was to assist Osiris in the weighing of the heart in the judgement of the dead. The Ancient Egyptian Book of the Dead depicts a scene in which a scribe's heart is weighed against the feather of truth.

The original form of a balance consisted of a beam with a fulcrum at its center. For highest accuracy, the fulcrum would consist of a sharp V-shaped pivot seated in a shallower V-shaped bearing. Balance scales that required equal weights on each side of the fulcrum have been used by everyone from apothecaries and assayers to jewelers and postal workers. 

The Romans also used balance scales for trade and taxation purposes, as well as in the production of coins. 

During medieval and Renaissance times, more precise weighing scales appeared. Beam scales, for example, used a lever system to increase precision and accuracy. In the 16th century, the invention of the steelyard, a type of lever scale, allowed for even greater accuracy in weighing objects. Ddesigned to be mounted to a wall, the most ingenious ones could be folded against the wall and moved out of the way when not in use.

Coin-operated weighing machines also became popular during this time, allowing merchants to charge customers based on the weight of the goods they were purchasing. Weighing scales became essential for commerce during this period, with merchants using them to ensure fair trade and prevent fraud. 

In 1669 the Frenchman Gilles Personne de Roberval presented a new kind of balance scale to the French Academy of Sciences. His scale consisted of a pair of vertical columns separated by a pair of equal-length arms and pivoting in the center of each arm from a central vertical column, creating a parallelogram. A peg extended from the side of each vertical column. To the amazement of observers, no matter where Roberval hung two equal weight along the peg, the scale still balanced. In this sense, the scale was revolutionary: it evolved into the more-commonly encountered form consisting of two pans placed on vertical column located above the fulcrum and the parallelogram below them. The advantage of the Roberval design was that no matter where equal weights had been placed in the pans, the scale would still balance.

In the 18th century, spring scales appeared. To produce these scales, a manufacturer would use the resistance of a spring to calculate weights, which could be read automatically on the scale’s face. The ease of use of spring scales over balance scales was what led most post offices to outfit their clerks with spring postal scales.

The Industrial Revolution brought about the development of mechanical weighing scales. Spring scales, invented in the 18th century, used a spring to measure weight. Industries such as agriculture and manufacturing commonly used them. Platform scales, invented in the 19th century, used a lever and counterbalance system, enabling manufacturers and merchants to weigh heavy loads such as industrial machinery. 

The traditional scale consists of two plates or bowls suspended at equal distances from a fulcrum. One plate holds an object of unknown mass, while objects of known mass, called weights, could be added to the other plate until the plates leveled off, indicating the masses are equal. The perfect scale rests at neutral. 

A spring scale, on the other hand, made use of a spring of known stiffness to determine mass. Suspending a certain mass will extend the spring by a certain amount depending on the spring's stiffness. The heavier the object, the more the spring stretches.

One of the most common types of spring scales was the kitchen scale—also known as a family or dial scale. Designed for horizontal surfaces, these vintage kitchen scales used the weight of goods in a pan at the top of the scale to force the spring down. Such scales, sold by Sears Roebuck and Montgomery Ward, became common in early-20th-century households. Many had flat weighing surfaces but some had shallow pans on top. Companies such as Salters, Chatillon, and Fairbanks made both.

One specialized type of spring scale was the egg scale, which grocers used to compute the weight of one egg or a dozen eggs. It also made it possible to classify eggs as to size—small, medium, large, or extra large. Jiffy-Way scales, made in Owatonna, Minnesota, beginning in 1940, became popular with collectors for their attractive red painted-metal housings. Another Minnesota company, Specialty Manufacturing Company made the Acme egg scale.

The weights used to balance scales varied from round, coin-like objects, each weighing a different incremental amount, to fancier ones shaped like bells. During the 19th and early 20th century, most scales were made of brass and/or cast metal. 

One of the most common antique scales is the postal scale. While those used in post offices were more elaborate, the basic design of inexpensive postal scales, sold in office supply stores, hasn’t changed since the late 19th century. 

In the 19th century, some merchants used portable suspension balance scales to weigh coins. Often the value of the gold in a coin exceeded the coin’s stamped denomination. These antique scales, designed to fit into wooden or metal cases, could be hung from the nearest hook. They included brass pans and cast iron or lead weights.

Another type of balance scale had a weighing pan on one side and an arm on the other. Known as an unequal arm balance scale, this variety had the counterweight built into the device. 

Counter scales used in dry-goods stores featured Japanned cast iron and bronze trim. Made by companies such as Howe and Fairbanks, the footed tin pans of these scales were often oblong, some encircled at one end so bulk items could be easily poured into a bag. Seamless pans were typically stamped from brass and given style names like Snuff, the smallest, and Birmingham, the largest. Manufacturers designed some counter scales for measuring spices while others weighed slices of cake.

Scales come in all sizes and varieties and prices, making them an excellent item with which to begin or expand a collection.

Miniature Relief Portraits in Stone

 

QUESTION: When I was very young, my mother would take me to visit my great grandmother. The first time I saw her she was wearing a beautiful pin with the picture of a lady carved on it. She later told me it was a cameo, given to her by her mother. She also had several others in different colors and designs. Needless to say, she has since passed, leaving her cameos to me. They are so beautiful but seem outdated by today’s standards. I may begin adding to the ones she gave me and would like to know more about their history and how I can tell how old they are. 

ANSWER: While cameos may not be in style today, they are nevertheless a great thing to collect. They span all periods from ancient to the early 20th century.

Cameos have been around since 15,000 B.C.E, appearing first as carvings on rocks to record significant events in ancient Egypt. 

During the reign of Alexander the Great in the 3rd century B.C.E., Greek and Roman cameos featured religious figures and mythological images. During the Greek Hellenistic era, women wore cameos to display their willingness to engage in intercourse. Quattrocento collectors, those from the 15th century Italian cultural and arts period, began distinguishing among the ancient cameos. 

Upper class women began wearing carved gemstones as a sign of wealth and prestige in the 18th century. Carvers soon realized they could use Plaster of Paris molds to recreate such gemstones as records of notable cameo collections. Scottish gem engraver and modeler James Tassie began using these molds recreate glass pastes that could pass as authentic, carved jewels.

Carvers realized just how easily they could replicate expensive jewels. They discovered Cornelian shells, which were soft, durable, and easy to carve. In the 19th century, England’s Queen Victoria popularized shelled cameos. As interest grew, Napoleon took a particular interest in them. He brought carvers to France from all over Europe to create cameo jewelry for both men and women. 

The Industrial Revolution produced an affluent middle class with plenty of money, and leisure time in which to spend it. Scores of Victorians broadened their horizons with travel, taking the Grand Tour of the European continent, and acquiring mementos and small gifts along the way to bring home for friends and loved ones. An essential stop on every Grand Tour was Italy.

A new type of cameo, made of petrified lava, also appeared in the 19th century. Colored lava extracted from an archaeological dig at Pompeii proved useful for highly detailed carvings. Women during this time were embarking on their Grand Tours, which were traditional trips were taken by wealthy young European men and women serving as an educational rite of passage. Women often purchased lava cameos as souvenirs of their travels, which established them as symbols of status and wealth.

But what exactly is a cameo? A cameo is a small piece of sculpture, often a profiled head in relief, on a stone or shell cut in one layer with another contrasting layer serving as the background. They could be made of any layered material capable of being carved so that the layers underneath were exposed. Over the centuries, cameos have been made of shell, stone, lava, gemstones, plastic and glass.

Cameos most commonly appear as portraits of women, although other popular subjects are men, groups, scenery, animals and flowers. Classic cameos, such as the ones Victorian women brought back to England, were made of shell and often depicted Greek and Roman gods and goddesses, recognizable by the various symbols placed in their hair or else-where in the portrait. An example of this was Diana, the Goddess of the Hunt, always depicted with a crescent moon in her hair, and sometimes carrying a quiver of arrows and a bow.

There are several ways to date a cameo. The first is its construction. A Victorian brooch. made before the invention of the locking pin clasp, has a simple "C" clasp, indicating it was made before 1900. Also, the pin shaft in a Victorian brooch extended out past the rim of the brooch and was visible when a woman wore one. 

The hair, clothing, and even the nose of the subject can also identify an older cameo. A Greco-Victorian cameo, while a short bob will appear on a cameo made during the early 20th century. Clothing styles change too, so looking at the subject's style of dress can help one date a cameo. And then there's the nose. During the Victorian era, the "Roman" or aquiline nose, a long nose with a straight bridge, was a sign of classic beauty. Later, society came to view a smaller, upturned nose as most attractive. 

The finest, most expensive cameos are those made from semi-precious stones. Agate is one of the most popular since it’s difficult to carve and requires significantly more skill to produce. 

The rareness of a cameo is a stronger determinant of its value than its age. For example, though the Roman Empire predated the Renaissance era, Collectors consider Renaissance cameos more valuable because there are fewer of them. The metal used can also give an indication of the age of a cameo. If the mounting is a pinchbeck—an alloy of copper and zinc resembling gold—it was likely made between the early 18th century and mid-19th century. Gold electroplating wasn’t patented until 1840, so all cameos that are plated were carved after this date.

The setting, or framing, is one of the most important determinants of age and value. Those that are remounted are considerably less valuable. The setting will be different depending on the era from which it was produced. For example, Victorian cameos often feature confined, simple frames as opposed to the jeweled, pearled versions that followed decades later.

Collectors today look for skillful hand-carving, exquisite detail and interesting subjects. Also, a cameo should be judged on the content and quality of the setting, its size and, most importantly, its condition. It's a good idea to hold a cameo up to the light to look for stress lines and cracks, before purchasing. Details such as the creative use of the coloring of the shell or stone, and the adornment of the subject with jewels or other accessories will also increase the desirability, and therefore the price, of a cameo.

Inside Out

 

QUESTION: While browsing a recent antique show, I discovered a delightful little copper box with what looked like an embossed design. The dealer told me it was probably made around the turn of the 20th century or at least before World War I. She said the design was repoussé on copper. I’d like to know more about this repousse technique. Can you give me a bit of history and an explanation of how it’s done?

ANSWER: There are two techniques for hammering copper—chasing and repousse. The difference between the two is that chasing pushes the metal in from the front side while repousse pushes the metal out from the backside.  Both techniques frequently employ a backing to support the work material and confine the movement of the metal to the immediate area around the tool.

While the word repoussé comes from the French word repoussage, meaning "pushed up," the word chasing, which also derives from the French word chasser, meaning ”to drive out.” Repousse is a metalworking technique in which an artisan shaped a malleable metal by hammering from the reverse side to create a design in low relief. Chasing is a similar technique in which the piece is hammered on the front side, sinking the metal. The two techniques are often used in conjunction. Many metals can be used for chasing and repoussé work, including gold, silver, copper, and alloys such as steel, bronze, and pewter. Tool marks are often intentionally left visible.

With the simplest technique, sheet gold could be pressed into designs carved in intaglio in stone, bone, metal or even materials such as jet. The gold could be worked into the designs with wood tools or, more commonly, by hammering a wax or lead "force" over it.

Both techniques date from antiquity and have been used widely with gold and silver for fine detailed work, such as the burial mask of King Tutankhamun, and copper, tin, and bronze for larger sculptures, such as the Statue of Liberty. Both methods require only the simplest tools and materials, and yet allow great diversity of expression. They’re also more affordable, since there’s no loss or waste of metal, which mostly retains its original size and thickness.

Before the use of repousse, ancient artisans pressed gold sheet into a die to work it over a design in cameo relief. Here the detail would be greater on the back of the final design, so some final chasing from the front was often carried out to sharpen the detail.

In 1400 BCE, ancient Egyptians used resin and mud as a softer backing for repoussé. The use of patterned punches dates back to the first half of the 2nd millennium BCE  Craftsman made the simplest patterned punches using loops or scrolls of wire.

By 400 BCE., the ancient Greeks had begun using a combination of punches and dies on a beeswax backing to produce repousse on their bronze armor plates.

The resurgence of repousse and chasing first occurred in England during the late 19th century as part of the British Arts & Crafts Movement. Most notably was the work produced at the Keswick School of Industrial Arts, founded in 1884 by Canon Hardwicke and his wife, Edith Rawnsley, as an evening class in woodwork and repoussé metalwork at the Crosthwaite Parish Rooms, in Keswick, Cumbria. Hardwicke designed the curriculum to alleviate unemployment. The school  prospered, and within 10 years more than 100 men had attended classes. 

The school prospered and swiftly developed a reputation for high quality copper and silver decorative metalwork. By 1888 nearly 70 men were attending the classes. By 1890 the school was exhibiting nationally and winning prizes; Its students numbering over 100,  it had outgrown its cramped home in the parish rooms, forcing Rawnsley to raise funds for a purpose-built school nearby.

The Newlyn Industrial Class, later renamed the Newlyn Art Metal Industry, established in 1890 by John D. Mackensie, was similar to Keswick and shared a common purpose with it. Inspired by the teachings of John Ruskin, they aimed to provide a source of employment in small communities where work came and went with the seasons. At the Newlyn classes, held in a net loft above a fish-curing yard, the pupils were mainly fishermen, while at Keswick students were pencil makers, laborers, gardeners, shepherds, and tailors.

Both metal workshops specialized in the production of repoussé copper work, This technique and material was popular with amateur craftsmen and women across the country because it was easy to learn. A student placed a flat piece of copper face down on a bed of pitch, or, as in the Newlyn workshops, lead. These materials were chosen because they would yield to the force of the blows of the punch but would still support the metal. Once a student had punched the design out from the reverse, he or she turned the metal over and chased finer details on the front.

Captivating Cameos

QUESTION: A few years ago, I went on a trip to Italy. While traveling along the Amalfi Coast south of Rome on my way to visit the ruins of Pompeii, I discovered shop after shop filled with beautiful cameos. I bought several and would love to buy more. What can you tell me about the origins of cameos, and how can I tell if cameos are genuine? 

ANSWER: Cameos have been collectible since the Renaissance in the 15th century when wealthy women collected them as status symbols. Today, elderly Italian master carvers are retiring, causing an escalation in the prices for finely carved cameos. Plus, new laser-cut cameos from China have been flooding the market. It’s now a buyer-beware market where only an expert is able to discern a really good cameo.

A cameo is a form of carved bas-relief, which features portraits, landscapes, and mythological figures cut into a variety of materials, but most often into gemstones and shells. Artisans, both ancient and modern, have crafted cameos from two layers of one piece of material, the top of which protrudes from the background, creating a multi-dimensional artwork. Throughout history, these detailed reliefs have adorned pieces of jewelry, such as brooches, necklaces, bracelets, and rings. But the earliest cameo carvers took their inspiration from prehistoric petroglyphs, which documented important religious and symbolic imagery onto rock faces.

Cameos first appeared as far back as 15,000 BCE. where ancient Egyptian civilizations carved figures into rocks to record important events. Cameo artistry traveled between the ancient Mediterranean cultures through trade routes connecting Egypt, Greece, and Rome, and often depicted mythological themes while paying tribute to gods and goddesses. As the Roman Empire grew, cameo carvers began to incorporate political portraits into their pieces. Wealthy people could afford to buy the expensive gemstone cameos, while less wealthy ones bought glass cameos.

During the reign of Alexander the Great in the 3rd century B.C.E., Greek and Roman cameos incorporated religious figures and mythological images. Also during this time, specifically in the Hellenistic era, women wore cameos to display their willingness to engage in the act of lovemaking. By the 15th century, cameos produced in Italy began to differ from the ancient ones.

In the 18th century, wealthier women began wearing impressively carved gemstone cameos as a sign of wealth and prestige. Carvers soon realized they could use Plaster of Paris molds to recreate cameos from notable collections. Scottish gem engraver and modeler James Tassie began using molds of these famous cameos to recreate glass pastes that could pass as authentic, carved jewels.

Carvers realized just how easily they could replicate expensive jewels. They discovered the use of Cornelian shells, which were soft, durable, and easy to carve. Queen Victoria popularized shelled cameos, featuring natural and humanistic scenes carved onto deep-sea shells. Meanwhile, as interest in collecting cameos grew, French military leader Napoleon  He brought carvers from all over Europe into France to create cameo jewelry for both men and women. He even commissioned furniture to be designed with cameos carved out of precious gemstones like opal, sapphire, and garnet.

A new type of cameo made from lava rock also appeared during this time. Colored lava extracted from an archaeological dig at Pompeii proved useful for highly detailed carvings. Women often purchased lava cameos as mementos from their travels on their Grand Tours, which established the objects as a symbol of status and wealth.

Over the centuries, artisans have created cameos by carving figures in bas relief from precious gemstones such as onyx or agate, one of the most commonly used. The most common motif of antique cameo jewelry depicted a profile of a face or mythical creature. Whether ancient or modern, cameos typically have two colored layers—figures  carved in one layer raised on the background of the second layer. Today, workers in “cameo factories” carve cheap imitations in paste glass or in seashells. The best shells come from the coast of Africa. The shell, itself, has no value. It’s the quality of the carving that gives a shell cameo value.

The rareness of a cameo outweighs its age when determining its value. For example, though the Roman Empire predated the Renaissance era, experts consider Renaissance cameos more valuable as there were fewer produced back then.

It’s important to examine a cameo by holding it up to a light to ensure there are no major cracks. Those that have three or four layers of color and a metamorphic image, which includes several subjects, are particularly valuable. Further, colored stones like opal, lapis, and emerald are rare, so they’re even more expensive.

When purchasing a cameo, it’s necessary to use a magnifying glass to look on the inside of the rim of the setting for the gold value and for sharper cuts or fewer details. A signature makes it more valuable, but collectors seek some signatures more than others. Unfortunately, it takes an expert to find the signature of a laser-cut cameo. It’s easy for a novice collector to be fooled into buying them at greatly inflated prices.

Two sought-after designs are “The Three Graces,” a scene of three full figures in flowing garb. The other is “Rebecca at the Well,” a theme that usually includes a full figure of a woman, a cottage or a well, and often a bridge. Both are late 19th-century favorites.

Cameos made of gemstones are generally more valuable than those made of shell. But the medium isn’t as important as the quality of the carving.  Graceful, smooth-flowing lines with much detail are signs of a good one. The inferior ones seem to have sharper lines, fewer details, and a harsh look.

Scenic cameos, on the other hand, are generally pricier than bust cameos. A very popular motif around 1860 was what is known as ‘Rebecca at the Well.’ There are many variations on this theme, but they usually include a cottage, a bridge, and a girl.

Prices for cameos continue to rise, making them a good investment. One with a small bust or portrait might sell for $30 to $400 if well carved. Prices for larger scenes and unusual themes or with sought-after signatures may begin at $500 or $600 and go up from there.

Collectors often find smaller cameos at antique shows or shops for $100 to $150. But for those prices, experienced collectors don’t expect top quality. These cameos may be less expensive for several reasons. First, they usually have less detailed settings. Second, they’re usually smaller and unsigned. And third, they have been carved more recently and less artistically.
