Size Matters . Size, on many levels, makes a big difference in both clay bodies and glazes. For example, if you have a glaze recipe that calls for 30% silica and you used 325mesh silica, it would create a smooth and glossy glaze, but if you used silica sand (40 mesh), you would have a rough and crusty glaze.

The production of sand fillers is simple because it includes, at most, only washing and classification into grades differing in grain size. Because sand has a negligible degree of porosity, it has an extremely low specific surface area in the range from 40 to 160 cm 2 /g. The material usually contains more than % SiO 2, with absorbed water being at a negligible level (%).

and small grain size of the natural media types limit the size of media, and therefore size of feed that can be milled. For example, sand media typically breaks down to its natural grain size when exposed to the high intensity milling environment. Generally sands have grain sizes finer than 5 mm. This limits the feed size that the mill can treat.

The sand casting method falls into the latter category. Silica sand is the preferred moulding aggregate in sand casting, since it is readily available and is cheap worldwide. Foundry silica sand with a size distribution of between 50 and 60 AFS (220 to 250 microns) produces moulds with a good surface finish that requires low binder additions.

Industrial Sand. Industrial sand refers to high purity silica sand. Besides its purity, grain size is an important characteristic. Silica has a simple chemical formula: SiO 2. Silicon and oxygen are the most abundant elements in the Earth's crust; the most common mineral with this formula is quartz, although it may have many crystal forms.
