Novacite® is a quartz silica unique in the extender/filler market. Graded by micron size, the individual, unagglomerated particles tend toward a platey structure, which promotes superior leveling, meshing and wear-resistance in many performance applications.

Mined and processed in Hot Springs, Arkansas, USA. The product is a "rotted", or powdered form of Novaculite mineral. It is also known as Arkansas Whetstone because it is a massive white quartz rock used to make whetstones for sharpening knives.

According to the Arkansas Geological Commission it is "a sedimentary rock composed mostly of microcrystalline quartz and is a recrystallized variety of chert. It is dense, hard, white to grayish-black in color, translucent on thin edges, and has a dull to waxy luster.".

Typical applications other than ceramics include casting resins, potting compounds, molding compounds, abrasive medium (wet blasting), latex paints.
