Baccarat acid marks refer to specific etches or patterns applied to Baccarat crystal products using acid. This technique creates permanent decorative designs on the glass surface. 
The process involves using a corrosive substance to selectively remove layers of the crystal. This results in frosted or textured areas that form intricate patterns, logos, or identification marks.
These marks are often used for authentication purposes and decorative elements on high-quality Baccarat crystalware, including glassware, vases, and decorative items. |
