Corrective fritts are fritts with a high or low coefficient of thermal expansion, designed to achieve the required values of this parameter in the glazes and engobes in which they are used.

Glossy fritts produce a fritted, glossy glaze with a lustrous, hard, vitreous finish. They are used to emphasize the depth of color and pattern.

Matte fritts produce fritted matte glazes with diffused light reflection. They are also used in half-baked glazes for the same purpose. They create a silky finish with a muted pattern.

Titanium fritts contain titanium dioxide (TiO₂), which acts as an effective opacifier. Due to the high refractive index of rutile crystals, they provide exceptional opacity and a white coating comparable to zirconium-based counterparts, while offering a number of technological advantages.
