It is imperative to be aware that a porcelain tile formation is based on three major raw materials, which are kaolinite clay, quartz and feldspar [3,5,7]. Tanzania is endowed with numerous kaolinite clay deposits in various places, of which some are believed to hold the largest reservoir in Africa [8-10], and perhaps the Pugu kaolin deposit is one of the

· Kaolin is frequently mixed with other clays and non-clay minerals based on their geological origin, such as montmorillonite, albite, quartz, illite, feldspar, dickite, and muscovite, among others. These minerals often determine the unique properties of each kaolinite clay while also affecting their reactivity [ 69 ].

Kaolin or china clay is a commercial clay composed principally of the hydrated aluminosilicate clay mineral kaolinite. The commercial value of kaolin is based on the mineral’s whiteness and its fine, controllable particle size. Particle size affects fluidity, strength, plasticity, colour, abrasiveness and ease of dispersion.
