Carnival glass

Since many manufacturers produced close copies of their rivals' popular patterns, carnival glass identification can be challenging even for an expert. Bullhead: A wristwatch chronograph with the movement rotated 90 degrees, placing the crown and buttons at the top of the watch rather than the traditional side. Identifying carnival glass involves matching patterns, colors, sheen, edges, thickness, and other factors from old manufacturer's trade catalogs, other known examples, or other reference material. Rattaprante: "lap time" on an analog stopwatch--the ability to pause the stopwatch display temporarily while continuing to record elapsed time. Many manufacturers did not include a maker's mark in their product, and some did for only part of the time they produced the glass. Registers: On an analog stopwatch, the subdials showing stopwatch minutes or hours. Identification of carnival glass is frequently difficult. A flyback will reset to zero and then continue to run when the reset button is pushed while the stopwatch is running.

Examples of carnival glass can be easily found in antique stores, and there is a very active market for it on eBay. Flyback: Most mechanical chronographs will only reset to zero when the stopwatch is stopped. Prices vary widely, with some pieces worth very little, while other, rare items command thousands of dollars. Analog-Digital chronographs will have a standard analog watch with permanent center seconds, and a separate digital display that will usually operate independantly of the analog section. Carnival glass is highly collectable. Digital chronograph will use a digital display for both timekeeping and stopwatch functions, either with separate displays or by switching modes on a single display. In addition, simple pressed glass was iridized by third parties as well. Typically the center hand will be used for stopwatch functions, while subdials may indicate "permanent" seconds, stopwatch minutes and hours, and in some quartz chronographs tenths or hundredths of a second.

Glass, as well as smaller quantities by many smaller manufacturers. An Analog chronograph shows both time and stopwatch functions with analog hands. Carnival glass was produced in large quantity by at least Fenton, Northwood, Imperial, Millersburg, Westmoreland, Dugan/Diamond, Cambridge, and U.S. A chronograph is a watch with both timekeeping and stopwatch functions. Other colors of uranium glass were produced in lesser quantities. Vaseline glass and uranium glass actually contains traces of uranium salts (uranium dioxide) in the glass, causing it to glow faintly in the dark with radioactivity.

It is also made in opaque white, called milk glass, and before the hazards of radiation were well known, it was made in semi-transparent or translucent pale green, called vaseline or uranium glass. Carnival glass is made in many translucent colors, primarily amethyst, marigold, cobalt, green, and red. The name "carnival glass" was not commonly used until collectors in the 1950s began to refer to it as such. Some significant production continuing outside the US through the depression years of the early 1930s, tapering off to very little by the 1940s.

Most US carnival glass was made between 1907 and 1925, with production tapering off by 1931. The popularity of this use made this a very profitable line for the Fenton company. Only after these markdowns was it frequently used as carnival prizes and as promotional giveaway items. However, it did not command the prices expected, and was subsequently discounted.

Decorative art glass called "Iridill" was originally produced by Fenton in 1907, inspired by Tiffany and Steuben art glass. After interest waned in the late 1920s, Fenton quit producing carnival glass for many years, but due to a resurgence in its popularity, Fenton produces carnival glass today. They were well known for quality, and were among a very few makers who made red carnival glass. The Fenton Art Glass Company was founded in 1905, and was the first and largest producer of carnival glass, producing many different pieces in over 150 patterns.

. Glass workers sometimes refer to carnival glass as "dope glass" because the process of applying the iridescent coloring to the surface is called "doping". Carnival glass gets its iridescent sheen from the application of metallic salts while the glass is still hot from the pressing. It is produced in the US and Britain from the early 20th century until the present.

Carnival glass is an inexpensive pressed glass, made as both functional and ornamental objects, mostly iridescent and of deep amethyst colour.
