Grit and glaze suspensions can differ not only in the amount of frit they contain but also in the particle size of their solid components. Generally speaking, granule suspensions are characterized by larger solid particles, which can enhance their technical and aesthetic performance. Once melted, ceramic glass tends to be more transparent and free of imperfections.

In contrast, the solid content of glazes, besides containing a certain amount of raw materials (lower percentage of high-quality material), is typically more finely ground. The smaller particle size facilitates the sintering and vitrification processes that occur inside the kilns. The smaller the particles, the greater their reactivity during firing.

Due to the rapid firing cycles, the melting and vitrification processes of glaze components may be incomplete. The particle size of frits, having already undergone a pre-vitrification process, can therefore be larger.

In grit suspensions, the glass is already formed, whereas with glazes, vitrification occurs only during the firing stage. This is why, in glaze suspensions, the presence of raw materials and frits that promote the development of ceramic glass is crucial.
