Carnival glass bowls form part of the large carnival glass collectible items. These are produced by pressing the glass and coating it with an iridescent coating which gives it shiny look. This process is known as doping, hence this glass is also sometimes referred to as dope glass. This process was first adopted in the early 1900s and it lasted only till the mid to late thirties, and today is extinct.

The glass manufacturer Fenton is the first, largest and widely recognized producer of carnival glass. To start with, this company decorated blank glass produced by other companies. In 1907 they started creating carnival glass. Fenton marketed its glassware immediately after starting production as "Iridill" or iridescent ware. This became popular and many other companies followed suit by making and marketing their own carnival glass bowls.

During the Depression in the late 1920s, demand on products began to decrease which impacted to sales reduction and partly dissemination of the market of glass companies. Because of this, some companies started selling merchandise to extremely low prices, which led to closure of business, just to get rid of stocks to carnivals which they use as prizes on games.

In the fifties, carnival glass bowls experienced a resurgence in popularity. Glass collectors coined the term "carnival glass" for these creations after learning of their term as carnival prizes. Several companies began making reproductions, and to this day carnival glass, especially antique Fenton glass, is a prized collectable.

Presently, carnival glass can be found in auctions, antique shops, and online for various prices. Fenton antique glass fetches high prices, as well as other well-known carnival glass. Some of the more common colors are marigold, as well as dark hues like blue and green. The most prized and pricey kinds of carnival glass bowls are red or pastel colored. One rare ice-blue plate even sold for $16,327.55 on a popular auction website!
