In-house produced Ceramics

Glazed alumina

Glazed alumina

A glaze is an impervious layer or coating of a vitreous substance that has been fused to a ceramic body through baking. It can serve your need as it is able to color, decorate and even waterproof an item and prevent adhesion problems.

Shape and size is changeable.
