At the time of introduction in late 1907 the carnival glass was called as Iridescent Ware. However, people started using the name carnival glass only after collectors in the 1950s began to refer to it as such. This innovative glassware made in highly patterned moulds had a vivid metallic sheen of changing hues on pressed glass articles. Iridescent Ware got the metallic sheen from a special spray of metallic salts on the glass while it was very hot.
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.
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.
Millersburg glass Company, Ohio was one of the largest producers of this kind of glass. Though the first glass product of the company were crystal, the Millersburg plant decided to produce iridescent glassware looking to the popularity of it. In this way the Millersburg Company brought out its line of Radium glassware.

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.
