Porcelain is a ceramic material made out of a triaxial composition of clay and kaolin, quartz, and feldspar. The usage of three Burkina Faso mineral resources in the formulation of porcelains has been investigated. The clay « NONG » contains 62 percent kaolinite, 18 percent illite, 17 percent quartz, and 17 percent rutile, according to the characterisation data (1 percent ). Albite (17%), muscovite (44%), and quartz are found in the pegmatite « PEG ». (34 percent ). Quartz makes up the majority of the sand « SAB ». Traditional hard porcelain requires 50 percent kaolin, 25 percent silica, and 25 percent feldspar in its formulation. Some samples were sintered at temperatures ranging from 1200°C to 1300°C after being cast into porous moulds. Clay « NONG » contributes to mullite recrystallization and the production of a vitreous phase during burning. At temperatures above 1050 °C, « PEG » contributes to the quantity and behaviour of the liquid phase. It aids in the management of the sintering process by allowing for a nearly zero (0.5%) open porosity. Because of its high melting point, « SAB » increases thermal and dimensional stability and is involved in recrystallization processes and liquid phase behaviour. The XRD analysis of all specimens revealed that it was made up of amorphous, mullite, and quartz phases. The specimens sintered at 1250 °C yielded the following intriguing results: a density of 2.3 to 2.5; a water absorption of less than 0.5 percent; an open porosity of less than 1%; and a flexural strength of greater than 35 MPa As a result, materials burned at temperatures higher than this are closely related to the porcelain group.
