Vintage Acid Etched Glass Vase Galle High-Quality Reproduction With Stamp. Glass etching, or "French embossing," is a popular technique developed during the mid-1800s that is still widely used in both residential and commercial spaces today. Glass etching comprises the techniques of creating art on the surface of glass by applying acidic, caustic, or abrasive substances. Traditionally this is done after the glass is blown or cast, although mold-etching has replaced some forms of surface etching. The removal of minute amounts of glass causes the characteristic rough surface and translucent quality of frosted glass. The floral vase is 4" x 4" x 11 1/2" and is in a good, vintage condition with light wear and no cracks or chips.
