Cut glass refers to glass that has been shaped and polished using a cutting tool to create intricate designs and patterns on its surface. This technique enhances the glass's appearance by refracting light, resulting in a sparkling effect. Cut glass is often used for decorative items, such as vases, bowls, and stemware. The process of creating cut glass involves skilled craftsmanship, where artisans use various tools to carve designs into the glass. Popular styles of cut glass include Brilliant Period cut glass, known for its deep cuts and elaborate patterns, and Czech glass, which features unique designs and vibrant colors.
