The article describes the influence of the technological impact the firing process has on ceramics structure. The process of forming a ceramic crock is described, which is represented by crystalline phase and glass phase. The dependences of the end product properties on the phases constituting its structure are described. Using X-ray phase analysis and electron microscopy, the authors studied ceramics produced from three types of clay materials with different content of clay minerals (kaolinite and montmorillonite). The change in the phase composition of the ceramic crock depending on the firing temperature is described. A conclusion was made on the fact that the structure is mainly glass phase with crystalline impurity inclusions. A necessity has been revealed for producing ordered structure for mullite.
