These are coloured glass pigments for mixing with binder to create paint.
These mimic the lustre of ground minerals.
The colored glass is produced by melting lead crystal glass with heavy metal oxides, thus a wide variety of colors is achieved. The light fastness of all colored glass powders is excellent (8,8,8). The colored glass pigments can be used in all media, such as oil, acrylic dispersions, lime and all kinds of glues. In certain mortars and cements the pigments may cause blooming. For application in exterior environments it is advisable to do trials first.
The colored glass is crushed and then ground to a gritty powder of about 0.25 mm. The powder is then sieved.
Safety advice: Avoid formation of dust. Do not inhale dust.
Grade < 63 The finest powder is also the lightest powder, it easily can be worked with the brush in any media (e.g. watercolor, print, glazing, etc.).
Grade > 125 The particles can be literally moved around on the surface, ideal for fresco techniques and sand-like textures.
