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.

Carnival glass is an inexpensive pressed glass, made as both functional and ornamental objects, found in a wide spectrum of colors. This glass is sometimes referred to as dope glass by the glass workers because the process of applying the iridescent coloring to the surface is called doping. Its production started in 1907 in many different pieces in over 150 patterns. However, it did not command the prices expected, and was subsequently discounted.

Translucent colors such as amethyst, marigold, cobalt, green, and red compose this glass, though it is also made in an opaque white referred to as milk glass. The glass was also made in semi-transparent or translucent pale green, and was called Vaseline or uranium glass; trace amounts of uranium salts were contained in the glass, which could produce a faint green glass glow in reaction to UV light. This was, of course, before the hazards of radiation were fully known and understood.

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. So in the beginning of 1910 the Millersburg Company started its line of Radium glasswares

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.

Identification of carnival glass is a very difficult task. Most of the manufacturers did not include a maker’s mark in their product, while the others did so only for part of the time they produced the glass. To identify this glass, one has to match patterns, colors, sheen, edges, thickness, and other factors from old manufacturer’s trade catalogs, other known examples, or other reference material. Since many manufacturers produced close copies of their rivals’ popular patterns, identifying it is a challenge even for an expert.

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.
