What is Wavy Glass?

Properties of Wavy Glass

The early manufacturing methods for float glass caused subtle waves to appear. Glass produced between the 1700s and early 1900s have this antique “wavy glass” appearance. Another name for the old-looking glass is restoration window glass. The distortion and imperfections appear when looking at the glass from angles or looking straight through it. The earlier the glass was produced, the more likely it will have small seeds or pits and heavy cords (reams) throughout. In the 1950’s,  smooth float glass was manufactured using the Pilkington Process. Glass throughout history has evolved, but antique glass is here to stay. Preservationists love to keep the antique charm of the wavy glass windows. Mouthblown glass is the manufacturing method for authentic historic glass. Alternative products, such as Circa 1800 & 1900 are made by other means. These alternative products have the same look and feel as mouthblown glass, but come in a variety of sheet sizes and thicknesses. This allows for more flexibility in the application. View our Wavy Glass and Antique Glass patterns.
