Satin-finished glass is made from clear glass and processed into an opaque but translucent glass . This result can be obtained using different techniques such as sandblasting , screen printing or treatment with hydrofluoric acid . With the sandblasting technique, the clear glass is blasted with fine corundum grains until it has become rough and cloudy.

Blasting glass with sand is forbidden because of the respiratory tract and the risk of lung disease ( silicosis ). Instead, corundum is used . This is an artificial, mineral abrasive and is melted from high quality bauxite or alumina in an electric arc furnace at over 2000 ° C. It is also used to make abrasive tools and sandpaper . Blasted corundum is not hygroscopic . By selecting different grain sizes, different degrees of roughness and thus different design options result.

A special form is the so-called muslin glass , in which the surface is only partially satinised in geometric shapes, so that a pattern reminiscent of lace is created from transparent and opaque areas.
