Guide to collecting carnival glass, America’s iridescent glassware

This guide to collecting Carnival Glass offers

Ellen Schroy

Carnival glass is what is fondly called mass-produced iridescent glassware. The term “carnival glass” has evolved through the years as glass collectors have responded to the idea that much of this beautiful glassware was made as giveaway glass at local carnivals and fairs. However, more of it was made and sold through the same channels as pattern glass and Depression glass. Some patterns were indeed giveaways, and others were used as advertising premiums, souvenirs, etc. Whatever the origin, the term “carnival glass” today encompasses glassware that is usually pattern molded and treated with metallic salts, creating that unique coloration that is so desirable to collectors.

Carnival glass is iridized glassware that is created by pressing hot molten glass into molds, just as pattern glass had evolved. Some forms are hand finished, while others are completely formed by molds. To achieve the marvelous iridescent colors that carnival glass collectors seek, a process was developed where a liquid solution of metallic salts was put onto the still hot glass form after it was unmolded. As the liquid evaporated, a fine metallic surface was left which refracts light into wonderful colors. The name given to the iridescent spray by early glassmakers was “dope.”

Many of the forms created by carnival glass manufacturers were accessories to the china American housewives so loved. By the early 1900s, consumers could find carnival glassware at such popular stores as F. W. Woolworth and McCrory’s. To capitalize on the popular fancy for these colored wares, some other industries bought large quantities of carnival glass and turned them into “packers.” This term reflects the practice where baking powder, mustard, or other household products were packed into a special piece of glass that could take on another life after the original product was used.

Lee Manufacturing Co. used iridized carnival glass as premiums for its baking powder and other products, causing some early carnival glass to be known by the generic term “Baking Powder Glass.”

Classic carnival glass production began in the early 1900s and continued about 20 years, but no one really documented or researched production until the first collecting wave struck in 1960.

It is important to remember that carnival glasswares were sold in department stores as well as mass merchants rather than through the general store often associated with a young America. Glassware by this time was mass-produced and sold in large quantities by such enterprising companies as Butler Brothers. When the economics of the country soured in the 1920s, those interested in purchasing iridized glassware were not spared. Many of the leftover inventories of glasshouses that hoped to sell this mass-produced glassware found their way to wholesalers who in turn sold the wares to those who offered the glittering glass as prizes at carnivals, fairs, circuses, etc. Possibly because this was the last venue people associated the iridized glassware with, it became known as “carnival glass.”

Carnival glass finds its roots in Ohio Valley

Much of vintage American carnival glassware was created in the Ohio valley, in the glasshouse-rich areas of Pennsylvania, Ohio, and West Virginia. The abundance of natural materials, good transportation, and skilled craftsmen that created the early American pattern glass manufacturing companies allowed many of them to add carnival glass to their production lines. Brief company histories of the major carnival glass manufacturers follow:

Cambridge Glass Company (Cambridge)
Cambridge Glass was a rather minor player in the carnival glass marketplace. Founded in 1901 as a new factory in Cambridge, Ohio, it focused on producing fine crystal tablewares. What carnival glass it did produce was imitation cut-glass patterns.

Colors used by Cambridge include marigold, as well as few others. Forms found in carnival glass by Cambridge include tablewares and vases, some with its trademark “Near-Cut.”

Diamond Glass Company (Diamond)
This company was started as the Dugan brothers (see Dugan Glass Company) departed the carnival glass-making scene in 1913. However, Alfred Dugan returned and became general manager until his death in 1928. After a disastrous fire in June of 1931, the factory closed.

Dugan Glass Company (Dugan)
The history of the Dugan Glass Company is closely related to Harry Northwood (see Northwood Glass Company), whose cousin, Thomas Dugan, became plant manager at the Northwood Glass Company in Indiana, Pennsylvania, in 1895. By 1904, Dugan and his partner W. G. Minnemayer bought the former Northwood factory from the now defunct National Glass conglomerate and opened as the Dugan Glass Company. Dugan’s brother, Alfred, joined the company and stayed until it became the Diamond Glass Company in 1913. At this time, Thomas Dugan moved to the Cambridge Glass Company, later Duncan and Miller and finally Hocking, Lancaster. Alfred left Diamond Glass, too, but later returned.
Understanding how the Northwood and Dugan families were connected helps collectors understand the linkage of these three companies. Their productions were similar; molds were swapped, retooled, etc.

Colors attributed to Dugan and Diamond include amethyst, marigold, peach opalescent, and white. The company developed deep amethyst shades, some almost black.
Forms made by both Dugan and Diamond mirrored what other glass companies were producing. The significant contribution by Dugan and later Diamond were feet – either ball or spatula shapes. They are also known for deeply crimped edges.

Fenton Art Glass Company (Fenton)
Frank Leslie Fenton and his brothers, John W. Fenton and Charles H. Fenton, founded this truly American glassmaker in 1905 in Martins Ferry, Ohio. Early production was of blanks, which the brothers soon learned to decorate themselves. They moved to a larger factory in Williamstown, West Virginia.

By 1907, Fenton was experimenting with iridescent glass, developing patterns and the metallic salt formulas that it became so famous for. Production of carnival glass continued at Fenton until the early 1930s. In 1970, Fenton began to reissue carnival glass, creating new colors and forms as well as using traditional patterns.

Colors developed by Fenton are numerous. The company developed red and Celeste blue in the 1920s; a translucent pale blue, known as Persian blue, is also one of its more distinctive colors, as is a light yellow-green color known as vaseline. Fenton also produced delicate opalescent colors including amethyst opalescent and red opalescent. Because the Fenton brothers learned how to decorate their own blanks, they also promoted the addition of enamel decoration to some of their carnival glass patterns.

Forms made by Fenton are also numerous. What distinguishes Fenton from other glassmakers is its attention to detail and hand finishing processes. Edges are found scalloped, fluted, tightly crimped, frilled, or pinched into a candy ribbon edge, also referred to as 3-in-1 edge.

Imperial Glass Company (Imperial)
Edward Muhleman and a syndicate founded the Imperial Glass Company at Bellaire, Ohio, in 1901, with production beginning in 1904. It started with pressed glass tableware patterns as well as lighting fixtures. The company’s marketing strategy included selling to important retailers of its day, such as F. W. Woolworth and McCrory and Kresge, to get glassware into the hands of American housewives. Imperial also became a major exporter of glassware, including its brilliant carnival patterns. During the Depression, it filed for bankruptcy in 1931, but was able to continue on. By 1962, it was again producing carnival glass patterns. By April 1985, the factory was closed and the molds sold.

Colors made by Imperial include typical carnival colors such as marigold. It added interesting shades of green, known as helios, a pale ginger ale shade known as clambroth, and a brownish smoke shade.

Forms created by Imperial tend to be functional, such as berry sets and table sets. Patterns vary from wonderful imitation cut glass patterns to detailed florals and naturalistic designs.

Millersburg Glass Company (Millersburg)
John W. Fenton started the Millersburg Glass Company in September 1908. Perhaps it was the factory’s more obscure location or the lack of business experience by John Fenton, but the company failed by 1911.

The factory was bought by Samuel Fair and John Fenton, and renamed the Radium Glass Company, but it lasted only a year.

Colors produced by Millersburg are amethyst, green, and marigold. Shades such as blue and vaseline were added on rare occasions. The company is well known for its bright radium finishes.

Forms produced at Millersburg are mostly bowls and vases. Pattern designers at Millersburg often took one theme and developed several patterns from it. Millersburg often used one pattern for the interior and a different pattern for the exterior.

Northwood Glass Company (Northwood)
Englishman Harry Northwood founded the Northwood Glass Company. He developed his glass formulas for carnival glass, naming it “Golden Iris” in 1908. Northwood was one of the pioneers of the glass manufacturers who marked his wares. Marks range from a full script signature to a simple underscored capital N in a circle. However, not all Northwood glassware is marked.

Colors that Northwood created were many. Collectors prefer its pastels, such as ice blue, ice green, and white. It is also known for several stunning blue shades. The one color that Northwood did not develop was red.

Forms of Northwood patterns range from typical table sets, bowls, and water sets to whimsical novelties, such as a pattern known as Corn, which realistically depicts an ear of corn.

United States Glass Company (US Glass)
In 1891, a consortium of 15 American glass manufacturers joined together as the United States Glass Company. This company was successful in continuing pattern glass production, as well as developing new glass lines. By 1911, it had begun limited production of carnival glass lines, often using existing pattern glass tableware molds. By the time a tornado destroyed the last of its glass factories in Glassport in 1963, it was no longer producing glassware.

Colors associated with US Glass are marigold, white, and a rich honey amber. Forms tend to be table sets and functional forms.

Westmoreland Glass Company (Westmoreland)
Started as the Westmoreland Specialty Company, Grapeville, Pennsylvania, in 1889, this company originally made novelties and glass packing containers, such as candy containers. Researchers have identified its patterns being advertised by Butler Brothers as early as 1908. Carnival glass production continued into the 1920s. In the 1970s, Westmoreland, too, begin to reissue carnival glass patterns and novelties. However, this ceased in February of 1996 when the factory burned.

Colors originally used by Westmoreland were typical carnival colors, such as blue and marigold. Forms include tablewares and functional forms, containers, etc.
