How Do You Spell CROWN GLASS?

Pronunciation: [kɹˈa͡ʊn ɡlˈas] (IPA)

Crown glass (/kraʊn ɡlas/) is a type of glass that was popular in the 18th and 19th centuries. Its name comes from the shape of the glassblower's tool, which resembled a crown. Crown glass is made by blowing a large bubble of glass, which is then spun quickly until it forms a perfectly flat disc. This method creates a glass that is thinner in the center and thicker around the edges. Crown glass was used for windows, lenses, and other optical devices due to its clarity and ability to bend light.

CROWN GLASS Meaning and Definition

1. Crown glass is a term used to describe a type of glass that is known for its exceptional optical qualities. It is a type of hand-blown glass that was commonly used in the production of windows, lenses, and other optical instruments during the 17th and 18th centuries.

   The manufacturing process of crown glass involves heating a large glass ball, commonly known as a "gather," until it becomes viscous. The gather is then attached to the end of a long blowpipe, and the glassblower blows air into the pipe, causing the gather to inflate into a hollow bubble. The bubble is then swung, spun, and flattened to create a flat, circular disk. This disk is known as a "crown," which gives the glass its name.

   Crown glass is highly valued for its optical properties. It has low dispersion, meaning that it can separate white light into its component colors with minimal distortion or color aberration. Additionally, crown glass has good refractive properties, allowing it to bend and focus light effectively.

   While crown glass was widely used in the past, it has been largely replaced by more modern glass manufacturing techniques and materials. However, it still holds significance in historical restoration projects and is considered a valuable artifact in the field of optics and glass production.

Etymology of CROWN GLASS

The term "crown glass" has its origins in the manufacturing process and the shape of the glass itself.

The word "crown" comes from the Latin word "corona", meaning "crown" or "wreath". It refers to the shape of the glass that resembles the curve of a crown when viewed from the side.

The word "glass" is derived from the Old English word "glas", which ultimately traces back to the Proto-Germanic word "glasam". It refers to the transparent and brittle material made by heating silica or sand.

"Crown glass" specifically refers to a type of glass that was historically handmade by glassblowers. The process involved blowing a large hollow sphere, which was then flattened and spun rapidly to create a circular shape with a thin center and thick, curved edges. This resulted in a disk of glass with a distinctive shape, resembling the curve of a crown.
