All That Glitters Isn’t Always Tiffany

QUESTION: I recently bought what I thought was a Tiffany lamp. I paid several hundred dollars for it and thought it was a steal. Now I'm not so sure. I cannot find a signature on it anywhere. Can you tell me if you think it's a Tiffany?

ANSWER: Unfortunately, as the old saying goes, "You got robbed." Well, not exactly. No, your lamp isn't a Tiffany. It's not even close. But what you paid for it probably is what it's worth. And as long as you like it, that's what counts.

The sight of what looks like a Tiffany lamp sends some people into a dream-like state, blinded by the dollar signs in their eyes. Others begin to see dollar signs at the mere mention of the name. Tiffany lamps have become the Holy Grail of antique collecting for many people. To find one—to own one—is paramount to winning the MegaMillions jackpot. And there lies the rub.

Because lamps made by Tiffany Studios command such a high price, people tend to lump all stained glass lamps into this one category. They think that any stained glass lamp is a Tiffany and that they’ll be set for life. In a million-to-one shot, they just might be, but more than likely, their lamp had been made by another company. While its not a fake, neither is it a Tiffany.

Between 1895 and 1915, small factories in New York and Chicago produced a huge variety of mosaic stained glass lamps to satisfy a growing demand for stylish lighting designs to complement the new electric lamps. While Tiffany Studios set the industry standard, other companies produced excellent designs as well.

Companies such as Duffner & Kimberly and Gorham, made lamps of a quality equal to Tiffany Studios and created styles that appealed more to the Victorian taste, although on its way out, that the American middle and upper middle class preferred. Some companies, like Wilkinson, made high quality bases, and took short cuts with their shades. Others, like Unique, focused on creating complex shades and paired them with simpler bases. Many copied Tiffany’s Art Nouveau designs—in many instances almost exactly—and many copied each other.

Tiffany lamps are about the most flamboyant art objects ever produced in America. They attract celebrities, speculators, and decorators, whose buying whims have driven the Tiffany market into a frenzy and then leave it a shambles when the next fad comes along. For the last few years, the market for these wonderful leaded-glass lamps, most produced during the first two decades of this century, has been recuperating from a decade-long manic-depressive binge.

During the 1950's, a few pioneer collectors began looking at the sensuous floral lamps made by Louis Comfort Tiffany and his Tiffany Studios. Louis was the son of the founder of the famous New York jewelry firm, but for most of his life he preferred painting, the  decorative arts, and interior design.




During the 1960s, interest in the lamps grew rapidly because their restless, fragmented, colorful designs fit nicely into eclectic, psychedelic decorating schemes of that time. Inflation in the 1970's drew investors, speculators, and celebrities into a market where prices sometimes doubled from year to year. Recession in the early 1980's drove those buyers from the market, and prices collapsed. Since then, prices for  some lamps have moved back to, or even above, their former highs; but the market is still very selective one.

The current record price for a Tiffany lamp is the $528,000 paid in December, 1984, at  Christie's in New York City for a large floor lamp with a shade in the Magnolia pattern.  The lamp was one of several being sold by record producer David Geffen, who had been a major Tiffany buyer during the era of hectic growth. Although it was set long after those halcyon days, the record was more a last gasp than a portent of things to come. Today, authentic lamps made by Tiffany Studios and signed either “Louis Comfort Tiffany” or “Tiffany Studios” on the rim of the shade go for as high as $30,000. No wonder there are so many “Tiffphonies” out there.

Beauty Is in the Eyes of the Beholder

QUESTION: Recently, I purchased a pressed glass plate that seems to be painted red and gold on one side. The paint is in pretty good condition, although some of it has flaked off. Did someone purposely paint this plate. I don’t want to scrape off the remaining paint until I know for sure. What can you tell me about this plate? And was the paint applied at the time of its manufacture?

ANSWER: As the old saying goes, “beauty is in the eyes of the beholder.” You bought the plate because you liked it, but the paint on it does make it look like someone was doing a bit of their own decorating. Fortunately for you, you asked about it before scraping away the paint. Your plate is what’s known as “Goofus” Glass. Sounds goofy, doesn’t it. In fact, some people call it tacky, some call it ordinary, and, yes, some call it beautiful.

Manufacturers didn’t originally call it "Goofus" glass. They had no designation of Goofus glass in their  salesmen's catalogs. They didn’t even recognize it as a specific classification of glass. Goofus glass, at its inception, was just a variety of pressed glass.

The term "Goofus" refers more to the use of unfired “cold” painted decoration to a piece of pressed glass, rather than to the glass itself. Many people believe the first users of Goofus noticed how easily the painted decoration on this glass wore away and felt that it was "goofy" or that someone had tried to "goof us."

Pressed, or pattern glass was, by the end of the 19th century, a substitute cut glass by the middle class. So the demand for pressed glass rose tremendously. To keep up with the demand, a number of new factories appeared, mostly in Pennsylvania, Ohio, West Virginia, and Indiana due to the availability of natural gas to fire their furnaces. The most prominent of these was the Northwood Glass Company, founded in 1887 in Martin's Ferry, Ohio.

One of Northwood’s original owners, Harry Northwood, later founded his own company, H. Northwood and Company in Wheeling, West Virginia in 1901. Within five years, his company had developed a reputation as America's finest glassware manufacturer.

Always innovative, Harry Northwood was probably the first to make what has come to be known as Goofus glass and, a few years later in 1908, Carnival glass.

Other companies, such as The Imperial Glass Co. of Bellaire, Ohio, focused immediately on Goofus glass. Soon others joined them, including the Crescent Glass Co. of Wellsburg, West Virginia, Lancaster Glass Company in Lancaster, Ohio, Westmoreland Glass of Grapeville, Pennsylvania, Dugan Glass Company. of Indiana, Pennsylvania,; McKee Glass Company of Jeannette, Pennsylvania, and Indiana Glass Company of Dunkirk, Indiana, which produced more Goofus glass than any other manufacturer.

Somewhere along the line, the idea to paint pressed glassware with bright colors— usually red, but sometimes green, pink, brown, orange, silver, and always some gold—gained popularity with the buying public, who scooped it up in large quantities. This popularity glass peaked between 1908 and 1918.

Manufacturers marketed Goofus glass with names evoking faraway exotic places and   wealth. Some of these included Egyptian Intaglio, Egyptian Art, Khedive (meaning "viceroys of Egypt"), Golden Oriental, Artistic Decorated, and Intaglio Art.

Because it was mass-produced and relatively cheap, retail shop owners bought it to give as a premium for buying their goods. Goofus glass was given away by every sort of business—furniture stores, car dealers, even at WW1 Bond drives. A person could buy a house and get a complete set of dishes. Or buy a new suit and get an intaglio fruit bowl. Or buy an engagement ring and get a vase or a set of dishes. Fair owners even awarded it as prizes for winning games. It was the first Carnival glass, preceding the iridized glass known as Carnival glass today.

Glass companies produced plates, bowls, vases, oil lamps, dresser sets, salt and pepper shakers and candle holders. Many of the Goofus patterns feature flowers and fruit, especially grapes, among other motifs, raised out of the surrounding glass as seen in vases, powder boxes and lamps. The pattern could also be pressed into the glass from beneath the surface providing an intaglio effect as found in Goofus plates, baskets and candy dishes.

Because of the extensive use of red, green, and gold paint, Goofus glass became known as “Mexican ware” because the colors reminded buyers of the colors in the Mexican flag.

Workers decorated the glass in one of two ways: They either covered one side or the other of the piece completely with paint, known as “All Over Decoration” or “AOD,” or they painted just the distinguishing pattern on the glass, leaving the remainder of the glass  untouched, known as "Pattern Decorated" or "PD." The more frequently seen surface textures are various "basket weave,” "fish net," and "stippled."  

By the beginning of the Great Depression, Goofus glass production had come to an end.

It’s difficult to find a piece of Goofus glass in perfect condition whether the paint was applied to the outside or the inside of a piece. The worn paint became so unsightly it was washed away by the original or subsequent owners.

Collectors pay more to own pieces made for special occasions or to commemorate a World’s Fair or another event than other nondescript pieces. They also look for complete sets such as a large berry bowl with matching smaller bowls. Goofus collectors seek out rare oil lamps complete with glass shade and matching base. Of course, Goofus glass in all shapes and forms in great condition with very little paint wear will bring a much better price than a piece with considerable paint loss.

Electric Lamps for Everyone

QUESTION: Several years ago, I bought an early electric glass lamp at a flea market. Although it was filthy and needed lots of TLC, I decided that I just couldn’t live without it. After giving it a thorough cleaning and having it rewired, I noticed how much it looked like the Tiffany lamps of the early 1900s. Upon further inspection, I noticed E M & Co. impressed into the base. So far, I’ve been unable to discover who E M & Co. is? Can you tell me who made my lamp and a little about it.

ANSWER: You’re the proud owner of a beautiful silhouette lamp—called that because of the silhouettes created by the shade when the lamp is on—made by the Edward Miller & Company of Meriden, Connecticut.

Unfortunately, when people think of metal and glass lamps of the early 20th century, they usually associate all lamps with Louis Comfort Tiffany. Then their eyes light up with dollar signs. But most of the lamps from this period were not made by Tiffany.

When Tiffany first began making his lamps, they were expensive to make and expensive to buy. Prices for them ran into the hundreds of dollars. Slag glass panel lamps, as they're known  today, had a few large pieces of glass fitted into a cast metal frame that simulated the effects of the more expensive leaded glass lamps. That made them affordable for the average person. A 1925 Sears, Roebuck and Co. catalog offers metal table lamps fitted with "art glass" priced from $6.90 to $19.

Many companies made this type of lamp. Often the lamps weren’t signed, but if the makers did mark them, they usually cast their mark into the metal on the bottom of the base. Sometimes they placed a mark on the metal edge of a shade or elsewhere on the base. Some lamps had paper labels, but most of them are long gone. Edward Miller & Company was one of many lamp makers.

The Miller Company began in 1844 in Meriden, Connecticut, as Joel Miller and Son. Originally, the company produced metal candle-holders, then moved on to kerosene lamps, gas lighting, and electric lighting. The name of the company changed, also, becoming Edward Miller & Company, then The Miller Company, both under the mark E M & CO on their lamp bases.

Although Miller produced expensive leaded glass lamps, the company took advantage of the opportunity to sell lighting to the middle classes as more homes became wired for electricity. The company sold lamps in bulk to utility companies in large cities who retailed them to their customers. A 1920 Philadelphia Electric Company catalog shows lamps with prices from $12.50 to $60, depending on size.

Miller took advantage of the latest discovery in lighting—electricity. Up to the last decade of the 19th century, everyone owned and used either gas or kerosene lamps. But the light they gave off was dim. The discovery of electricity led to lamps that glowed brighter in a downward direction, thus offering improved lighting for reading and sewing.

Though electrical lamps offered lots of advantages, there were problems with the carbon filaments in early incandescent light bulbs that didn't last long. The bulbs turned dark inside from carbon, and they used a lot of electricity per watt of light. The invention of the tungsten filament bulb and improvements to it made between 1906 and 1910 established electric lamps as a practical and reliable alternative to gas and kerosene.

These early electric lamps offered a variety of base and shade overlay designs, influenced by several style movements including Art Nouveau with its intricate curvy lines and botanical themes, Arts and Crafts with its simpler forms and straighter lines, and Orientalism with its Middle Eastern flavor. And with the discovery of King Tut's tomb in 1922 , people’s interest in everything Egyptian grew.

Lamp creators took their inspiration from all of these influences, giving consumers a choice of floral designs, geometric patterns, or scenes with camels, palm trees and pyramids. Other designs reflected Neo-Classical Revival architectural and furniture styles, employing fluted columns, garlands, and urns as design elements.

Manufacturers produced slag glass lamps with amber glass, as well as other colors. Amber was the dominant color because it proved to be the most restful for reading. These lamps often have more than one color of glass. Makers sometimes used various colors of slag glass to simulate sunsets or water behind their metal frames.

Today, these same slag lamps sell for $500 to $1.500, depending on style, size, and especially condition. Smaller varieties, known as boudoir lamps, sell for less while larger ones sell for more.

With the onset of the Great Depression, the market for more expensive dramatic, heavy lamps with glass shades faded and manufacturers responded with cheaper, lightweight lamps with paper or fabric shades.

19th Century Tupperware

QUESTION: I recently won a box lot at a local auction. Inside the box I found what looks like a cup with an attached saucer. It’s heavy and a bit crude. Can you tell me what it is?

ANSWER: What you have is a 19th-century grease lamp made of stoneware. Farmers used these lamps, fueled by animal fat, in their homes. They often threw away early, less refined versions, as better ones appeared on the market. 

Stoneware is one of the hardy perennials of the American antiques trade. Each year, auction houses, antiques shops, and flea markets sell thousands of pieces at prices from $25 to several thousand dollars. The record price stands at $15,000 for a rare 1773 stoneware inkstand. Only a handful of pieces fetch prices in that stratospheric range.

Stoneware is a heavy, hard pottery that resists odors and tastes and won’t absorb water. The first American stoneware appeared in the last half of the 18th century, and for more than 100 years people used stoneware vessels to store and transport foods and liquids. It was essentially the 19th-century version of Tupperware. When glass and metal containers came into common use, people stopped using it.

Generally, it’s difficult to date stoneware unless a piece has the name and town of the maker or the name of the company that used the vessel to hold its product stamped on the bottom. For this reason, many collectors like to buy pieces made in their areas. But stoneware that can be identified as the work of an early potter may be worth several hundred dollars. For example, a double-handled crock inscribed "Commeraw" sold for $800 because it was made by Thomas Commeraw, a New York City potter active from 1795 to 1820. At a Massachusetts auction, a jug with the initials J. F. sold for $600—it’s attributed to a 1790's Boston potter named Jonathan Fenton. Sometimes the initials on a piece belong not to the maker but to the original owner, which makes the piece attractive to collectors interested in genealogy.

As with many other antiques, age isn’t the main reason in determining the price of an object—its decorative qualities are far more important. An attractive late-19th-century jug will fetch more at auction than a homely Revolutionary-era piece. Most stoneware forms, such as jugs, crocks, jars, churns, and pitchers, are very simple and vary only slightly in shape and design. Decoration, if any, tends to be sparse. When a potter decorated his pieces, he often used simple floral, bird, or scroll motifs painted on the stoneware in three basic colors—blue, brown, or black. The most common stoneware style has a gray-glazed background with blue decoration. Such run-of-the-mill pieces, which represent about 90 percent of the stoneware available today, are generally worth less than $50.

Because many stoneware items look alike, the most valuable pieces are those with unusual or imaginative decoration. A rare form, such as your stoneware grease lamp, or an odd-sized piece, an exceptionally large crock, for example, can be worth several hundred to several thousand dollars.

Tips for Buying Antiques at Garage and Yard Sales

The ordinary garage/yard sale is an American institution. Every Saturday morning there’s one or more going on somewhere in the country. Collectors find it hard to pass them up since they’re the entry-level market for antiques and collectibles.

Most people who cruise the yard sales every weekend are casual shoppers, driving from one to another. If you’re a serious collector, you know how to find antiques and collectibles hidden among the plastic kitchenware and cheap florist vases, but you need a plan.

Generally, garage/yard sale ads appear in local papers on Thursday and Friday evenings. Mark those that mention antiques or collectibles. Don’t waste your time noting those that don’t advertise antiques. After all, you must complete your rounds in just a few hours, at least by 12 Noon.  

As you read the addresses, map a route starting with the sales closest to your home or those with the earliest starting times, then move on to more distant ones. The purpose is to get to the good sales before someone else snaps up the antiques.

Every town is different when it comes to finding antiques at good prices at these sales. You’ll usually find more antiques and collectibles at the lowest prices in older, middle-class neighborhoods. In many cases owners of these homes have lived there for years and years and have stored a mass of castoffs in their attics and basements. These people are usually not trying to get top dollar for their things. They just want to get rid of them.

By contrast, the owners of homes in upper-class neighborhoods are usually quite knowledgeable about antiques values. At their sales they set close to retail prices on any antique or collectible, so you’ll seldom find much to buy at such sales. Remember the cardinal rule of collecting: Buy low, sell high.

As many sellers get more savvy with the Internet, they look up their items on eBay to see what they’re going for. But they don’t take into account that this is an auction, as well as entertainment, so prices can be higher than they should be.

At these sales possession is nine-tenths of the law, so to speak. The unwritten code of the yard sale is that whoever has his or her hands on an item first has dibs on it. You need to be able to pick things up quickly and hold on to them. Take along a large sturdy plastic tote bag or a box, into which you can drop anything that interests you. This way, you can pick up and carry much more than you could in your arms alone. Then examine your finds carefully, put anything that isn’t promising back on the tables, pay for the items you do want, and move quickly to the next sale.

To be honest, you probably won’t find an antique or collectible of outstanding value at a garage or yard sale. You’ll find china, glassware, pottery, and kitchen collectibles, all of modest value. Every once in a while, you’ll come upon a piece of furniture—a bed, small table, brass bridge lamp, framed mirror, or whatever. Inevitably, these finds must be refinished, polished, or rewired.

Every collector has at least one story of a spectacular discovery, a real treasure bought for a pittance. To make sure you buy the real thing, take at least one of the current antiques and collectibles price guides with you—you can leave it in your car. Otherwise, unless you have a phenomenal memory, you’ll have a hard time remembering the thousands of ever changing retail values of items you’ll run across.

Some collectors learn this lesson the hard way. Many novice collectors go to yard sales without taking any price guides along. You might find an item you think is priced well, but you don’t know for sure. If you had brought along a general antiques and collectibles price guide, you’d have been able to decide if the price were too high or if you should make the purchase. If you left the sale to check on the price back home, you might return and find that the item had been sold. 

Going Retro

QUESTION: I recently purchased a one arm chair that has a metal stamp that says The B.L. Marble Chair Co. ,Bedford Ohio. It is a cool mid-century design and is walnut and leather. Do you know anything about this chair like what its purpose was?

ANSWER:  Barzilla L. Marble founded the B.L. Marble Chair Co. in 1894, after working at several other chair companies. His grandfather operated a chair factory in Marbletown, New York, and others in his family likewise made chairs, so it was natural for Marble to do so. He formed a brief partnership with A.L. Shattuck in 1885, but struck out on his own nine years later.

His company produced fine wooden chairs made for comfort and elegance that were made to last. Up until 1910, it produced chairs for the home, but during World War I, Marble added a division to make wooden aircraft propellers for the military.

By 1921. Marble’s company had outgrown its small wooden buildings and construction began on new brick buildings which had more than four acres of floor space. After Marble died in 1932,  A. D. Pettibone became president of the company and part owner. In 1953 Pettibone sold his interest in the Marble Chair Company to a group of local investors. Eventually, another man, also named Pettibone but not related to the first, bought the company, and it became extremely successful.

The company produced one-arm “modern” chairs most likely in the mid-60s under the second Pettibone owner. Furniture makers intended one-arm chairs, both originally in the 1870s and then in the 1960s as chairs to be placed in a corner. Today, most people would refer to these 1960's chairs as “retro” in style.

But exactly what does retro mean? According to the Oxford University Press Dictionary, retro means "imitative of a style from the recent past." Retro is a culturally outdated or aged style, trend, mode, or fashion, most likely from the 1940s through the 1960s. Currently, eBay offers over 468,000 different retro items at auction.

People born between the 1940 and 1950 became teenagers during the 1950s and 1960s. And because those two periods provide memories for many of them, anything retro is in, whether it’s furniture, accessories, clothing, and collectibles, especially those related to the Golden Age of Hollywood.

Life in the 1950s was conservative, but changes were about to take place. Such innovations as Velcro, Tang, frozen foods, transistor radios, Frisbees and the hula-hoop began to appear. Bill Haley and the Comets rocked around the clock while jukeboxes filled every burger joint and ice cream parlor with the new sounds.

Furniture and accessories, especially the ubiquitous pole lamp, featured streamlined styling in avocado and gold. By 1957 there were 47 million T.V. sets in America’s homes, four times the number of just seven years before. Families began to watch T.V. shows like “I Love Lucy” incessantly. They even ate in front of the T.V., thus necessitating the invention of the T.V. tray and comfortable casual furniture without frills.

Later on in the 1960s, the space race captured everyone’s attention as astronauts walked on the Moon and teens danced the twist to the music of Chubby Checker and sang along to Beatles’ tunes. More innovations such as lava lamps and electric knives caught on eventually providing the retro movement with lots of collectibles.

Tiffany Lamps Go for Big Bucks

QUESTION: An art dealer came to our house to look at a painting and noticed the Tiffany chandelier hanging in our dining room. A year and a half later, he called back with interest to purchase it for a significant amount in cash. I did some checking and discovered that an original Tiffany back in 1977 sold for $22,000. What is the best way (if I was even to consider selling it) to get the most value for what it's worth?

ANSWER: This is just one of many questions I have received about Tiffany lamps. The recession has got everyone looking to sell items that may have some value. And with the Antiques Roadshow highlighting some valuable Tifffany lamps, people have gotten dollar signs in their eyes.

Tiffany Studios, founded by Louis Comfort Tiffany, designed and produced the only authentic Tiffany lamps. Historically, Tiffany, himself, never actually made any of the lamps, but just oversaw their production and design. He personally guided the lamps that came from his studio  between 1899-1920 through all stages of their creation. This not only included the shades, but the handmade bronze bases as well.

Tiffany’s magnificent lamps were an instant commercial success. Wherever they appeared, they received prizes and awards. He was the first to design lamps to be operated using the new electricity, then only affordable by the wealthy. But once his lamps caught on, several other American companies, including Handel, the Pairpoint Corporation and Quezal, emulated his designs.. While Handel and Pairpoint concentrated upon creating innovative lampshades, often, but not always, in the style of Tiffany, Quezal helped to satisfy the increasing demand for the iridescent glassware, called favrile, popularized by Tiffany in America.

The name "Tiffany" has become a generic term for windows, lamps, and glass of–or imitating–the period. However, there were many other firms in the U.S. and in Europe doing similar and in many cases nearly identical work. This has lead to a great deal of confusion, and much work by other companies has been sold as "Tiffany,” often with false "Tiffany" signatures added to it.

It’s important to note Louis C. Tiffany and Tiffany Studios did NOT mark or sign many of their lamps in any way. However, it’s often easy to forge Tiffany signatures on similar-looking period or reproduction items. Many genuine Tiffany pieces that weren’t signed originally have probably had forged signatures added to them to increase their worth and make them easier to sell, as well.

By his vision and energy, Louis.C. Tiffany succeeded in blending classical motifs with bold new techniques in glassmaking to create a distinctive American art form. The demand for Tiffany lamps among today's collectors attests to the lasting value of his work. The table lamp with the wisteria design pictured above recently sold for over $600,000. If that doesn’t get dollar signs in people's eyes, nothing will.

If you have what you think may be a real Tiffany and it doesn't have a signature, send a photo and description of it to Christie's Auction House to have it verified.
