Acid etching is a decoration technique widely used in the cosmetic and fragrance sectors. The technique changes the opacity of glass so it can be rendered completely or partially translucent. The result is glass that winds up being beautifully decorated, with a touch of luxury and style.

The decoration process that uses acid etching involves a chemical process where the outer layers of a glass container are removed to give the bottle a nearly opaque, frosted appearance with a stunningly smooth finish. The technique, when combined with other decoration techniques can make the final product possess a subtle and elegant appearance.
