The objective of the present study was to analyse the relation between porcelain tile starting composition and tile microstructure and mechanical properties. Seven starting mixtures were prepared for this purpose, using experimental design in the quartz-kaolin-sodium feldspar ternary diagram, varying each constituent in a range of 30% by weight (quartz: 10–۴۰%;
kaolin: 20–۵۰%; sodium feldspar: 40–۷۰%). It was sought to reproduce industrial processing conditions in the laboratory as faithfully as possible. The firing temperature used was the maximum densification temperature. The mechanical behaviour of the pieces was evaluated by determining their bending strength and toughness
