Carnivale Glass: An Interesting Segment Of The Antiques Market

Carnival Glass, originally called Iridescent Ware, first came out in late 1907. It was not commonly referred to as Carnival Glass until the 1950s, though, when collectors started calling it that. These pieces were typically made from extremely ornate glass pieces, characterized by the myriad hues of their sheens. Their luster was achieved by applying metallic salt sprays to the glass before it had completely cooled down.

Made as both functional and ornamental objects and found in a wide array of colors, carnival glass is an inexpensive pressed glass, often called dope glass by glass factory workers because of the process of applying the iridescent coloring, which is known as doping. Its production can be traced back to as early as 1907, with many, many different pieces in over 150 distinct patterns. It did not, however, command the expected prices, and was subsequently discounted heavily.

This glass is available in many translucent colors like primarily amethyst, marigold, coblat, green and red. It is also made in opaque white which is also referred to as milk glass. This glass was also availale in semi-transparent or translucent pale green and was named as Vaseline or uranium glass before the harmful effects of radiation were known. Vaseline glass and uranium glass have small amount of uranium salts which make faint green glass glow on reaction with UV light.

One of the largest producers of this kind of glass was Millersburg glass Company, Ohio. The first glass products of the company were crystal, but the Millersburg plant decided to ride the wave of enthusiasm for iridescent glassware. Thus, in early 1910, the Millersburg Company brought out its line of Radium glassware

The prices of Carnival glass vary widely depending on their quality and availability. This glass is a highly collectible item with some of the pieces worth very little, while other, rarer items command thousands of dollars. There is a very active market for this item since it has become an antique glass collectible.

It is very hard to identify carnival glass. Most of the time, the makers didn’t mark their work, others only marked them part of the time. To figure out who made the glass one has to match, patterns, colors, sheen, edges, thickness and some other factures from old trade catalogs, examples of prior work or a reference material. Many manufacturers made dlose copies of rivals popular works to. So even for an experienced expert this is a hard task.

At the time of introduction in late 1907 the carnival glass was called as Iridescent Ware. However, people started using the name carnival only after collectors in the 1950s began to refer to it as such. Among the greatest producers of this type of glass was Millersburg glass Company in Ohio. The first glass products by that company were crystal however the Millersburg plant decided to follow success for iridescent glassware. There is a very active market for this item since it has become an antique glass collectible. So even for an experienced expert this is a hard task.
