Stretch Glass

What is Stretch Glass?

Stretch glass, also known as iridescent glass, is a unique type of glass that has been processed by re-heating and spraying metallic salts after the application of iridescence. This process creates a shimmering effect on the surface, giving the glass a glossy, matte finish. Stretch glass is different from carnival glass, which is heavily patterned and not re-heated, and it was made by several companies including Central Glass Works, Diamond Glassware Company, Fenton Art Glass, Imperial Glass, Jeannette Glass, King Glass, Lancaster Glass, Northwood Glass, Tiffin Glass, and Vineland Flint Glass Works.

The History of Stretch Glass

Stretch glass, which was first introduced in the United States around 1916, became very popular during the 1920s. Its popularity waned in the 1930s, but it has enjoyed a revival in recent years among glass enthusiasts and collectors. Stretch glass is often mistaken for art glass made by companies such as Steuben and Tiffany due to its iridescent appearance, although it is not produced by these companies.

How is Stretch Glass Made?

Stretch glass is typically made from plain pressed glass designs without surface decorations or patterns. It can be pressed or blown into molds, and while the piece is still hot, it is sprayed with metallic salts to achieve an iridescent effect. The glass is then reheated and "worked" in some manner, stretching the iridescent surface and producing an onion skin effect. Some pieces may have very obvious "stretch marks," while others have fine marks.

Classification of Stretch Glass

While some Stretch Glass pieces have very simple patterns, others may feature complex designs. It is important to note that not all Stretch Glass is created equal, and certain pieces may be more rare or valuable than others. The value of Stretch Glass is subject to supply and demand, and common pieces may sell for as little as $20, while hard-to-find items can command several hundred dollars.

Stretch Glass Patterns

Despite the relatively simple nature of most Stretch Glass pieces, some collectors claim ownership over certain patterns. Examples include Northwood's Concave Diamonds, which is found in a variety of settings, and Imperial's Smooth Panels vases, available in various colors. These patterns are highly sought after by Collectors.

Stretch Glass Collected and Apportioned

Like other types of glassware, Stretch Glass is often collected and apportioned by color, size, and form. Common pieces include plates, bowls, compotes, and vases. Some companies even made beverage sets consisting of a pitcher and tumblers with applied handles. Collectors often divide their collections based on era, manufacturer, and type of glassware.

Stretch Glass Prices

The prices of Stretch Glass pieces can vary widely depending on the demand, rarity, condition, and complexity of the pattern. Colored pieces like cobalt blue and red are especially sought after, while patterns such as Wisteria and Tangerine can command higher prices. As a general rule, more common pieces may sell for $20 to $30, while rarer or more valuable items can fetch four or five times that amount.
