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.

The year 2007 is a special year for glass collectors as they mark the centennial year of carnival glass. It was 100 years ago, in 1907, that carnival glass was first manufactured by The Fenton Art Glass Company.
