History Of Carnival Glass

Carnival glass has been around for quite some time now allowing us to carefully analyze how this concept evolved over the years and popularised among various collectors of the modern era. While carnival glass wasn’t as appealing or interesting to collectors and traders until the 1950s, it had already entered the market and various glass companies had taken interest in its production and distribution.

In the late 19th century, the idea of hand-operated press molds had been introduced by American glasshouses, which greatly promoted the production of domestic glassware. These molds were eventually used by companies and manufacturers for the production of pressed glass, which was a major upgrade on hand-blown glass that was in use previously.

By 1905, the production of the first carnival glass that was believed to rival the incredibly expensive Tiffany glass was reported and it soon entered the market. Carnival glass manufacturers completed their productions in a variety of ways, which is responsible for the incredible diversity that is apparent in the world of carnival glass. Other popular names that carnival glass was given over the years include poor man’s Tiffany, Rainbow glass, Cinderella glass, Dope glass, and Taffeta glass, based on the various attributes and features of this type of glass.

Flawless Quality

The quality of the piece is integral for deciding whether a piece is original or fake.

Fake Marks

In various circumstances, fake carnival glass is made from an original mold, allowing the manufacturer’s mark to seem similar to the original. However, you’ll still see various dissimilarities, allowing you to identify the mark as fake. These might be very insignificant differences, such as incorrect placement of text.

Fake Patterns

The next thing you need to look for is fake patterns. Patterns of certain antiques are easily replicated making it difficult for a beginner to distinguish between an original and a fake. For this, you are recommended to consult an expert or review a pattern book for the glass design in question.

Dull Surface
