To achieve the look of a matte, frosted appearance, a glass container is immersed in hydrofluoric acid/fluoride compounds. During this process, small bits of the glass surface are removed. This, in effect, leaves a surface that diffuses the light, giving a “frosted” appearance. Frosting can be applied to an entire container or used to create a design.
Advantages of frosting:
Adds a velvety texture to the container
Hides items such as diptubes or sediment in the container
Adds texture and a look of elegance
