It takes its name from the manufacturing process. The process is characterized by three phases: pressing into the moulds (the mixture is placed in the moulds and, after that, pressed), drying (the mould is dried so that deformation and cracks are not present) and cooking (products are burned in a kiln). It is called Single-fired because the cooking is required only once.

The single-fired has got lower technical properties (as resistance) compared to porcelain stoneware. However, this lack is offset by many aesthetic elements (like colours).
