Acid etched patterned glass, also known as acid carving glass, is a type of artistic glass created by printing or etching a design onto frosted glass, then soaking it in an acid solution for 20-50 minutes. This technique produces a variety of patterns and designs with three-dimensional, shiny, and full lines that cannot be achieved through traditional carving methods.

The time length of the glass soaking into the acid solution affects the depth and fullness of the design. The soaking time is determined based on the desired effect, and the achieved product can be further divided into a horizontal or vertical acid carving glass.

Acid carving glass is widely used in hotel decoration, home renovation, cabinets, sliding doors, and other applications. It is a chemically treated glass with lively and vivid patterns, which can be customized to meet customer needs.
