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.

"Carnival glass" refers to glass bowls given as carnival prizes in the early part of the 20th century, as well as reproductions made by several companies in the 1950s, thanks to renewed popularity at that time. Today, both the antique Fenton style and the later styles are prized by collectors.
