The raw materials are clays with finely divided quartz (sand) (0.02–0.04 mm) and feldspar, responsible for the rheology along the thermal processing. Clay is a group of minerals in earth that is granular; plastic, when mixed with a little water; or hard and brittle, if combusted.
What materials are used to make clay?
Ball clays typically contain kaolinite, quartz, mica, iron and titanium, organic matter and other minerals.
