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.

The demand for their products began to decline in the late twenties. The reason for the decline was the decreasing sales during the depresion and partly also due to the saturation of the market by glass companies. To reduce the dead stock companies began to sell their wares at deeply discounted prices to carnivals, which was used by the carnivals as prizes in their games. During this period many companies shut shop.

Known as "carnival glass" by glass collectors, the popularity of carnival glass bowls surged in the 1950s. Originally used as carnival prizes, today reproductions are made by several companies. Fenton glass in particular is a prized collectible and the most frequently manufactured.

At present, auctions, antique shops, and online stores are the best places where one could get carnival glass at various prices. Fenton antique glass as well as other well-known carnival glass fetches high prices. Popular colors of these glasses are marigold, as well as dark hues like blue and green. However, carnival glass bowls in red or pastel color are the costliest item of this category. On a popular auction website, one rare ice-blue plate sold for $16,327.55!
