Ceramic Glaze Mixture

Ceramic glaze is an impervious layer or coating of a vitreous substance which has been fused to a pottery body through firing. Glaze can serve to color, decorate or waterproof an item. Glazing renders earthenware vessels suitable for holding liquids, sealing the inherent porosity of unglazed biscuit earthenware. It also gives a tougher surface. Glaze is also used on stoneware and porcelain. In addition to their functionality, glazes can form a variety of surface finishes, including degrees of glossy or matte finish and color. Glazes may also enhance the underlying design or texture either unmodified or inscribed, carved or painted.

Most pottery produced in recent centuries has been glazed, other than pieces in unglazed biscuit porcelain, terracotta, or some other types. Tiles are almost always glazed on the surface face, and modern architectural terracotta is very often glazed. Glazed brick is also common. Domestic sanitary ware is invariably glazed, as are many ceramics used in industry, for example ceramic insulators for overhead power lines.

01: Transparent Glaze:A fully transparent glaze is simply one that does not have opacity. But there are degrees of transparency. For example, if a glaze is matte it may show the color of the underlying body and decoration, but these will be muted (so it is actually translucent).


02: Opaque Glaze:The opaque glass surface is rough and cloudy, and light is scattered as it passes through. Because light doesn’t reach the eye directly, opaque glass is dark. Frosted glass is transparent, but its surface is smooth. Light passes through it, but the surface reflects some of the light. This makes it light-reflecting instead of light-scattering.

Glaze Compound:

Glaze Compound material is a mixture of raw materials combined to make a composition. Raw Materials source to make glaze often are in the form of powder. Using various Raw Materials, we get various types of Glaze compound powder. On varying single quantity ratio of raw material can have an impact on the glazed look. Glaze compound is a powder used for ceramic ware by dipping or spraying. After this process, you will need to heat the glaze mixture, which turns into a vitrified stage. This will develop desirable ceramic properties for the surface of the ware.

Zinc Oxide:

Zinc oxide in ceramics has the main role to reduce the melting temperature; reduce the energy and equipment requirements while improving the intensity of color glazes.

Barium carbonate Powder:

Barium carbonate is widely used in the ceramics industry as an ingredient in glazes. It acts as a flux, a matting and crystallizing agent and combines with certain colouring oxides to produce unique colours not easily attainable by other means.

Aluminate: - Aluminium oxide (Al2O3):

Aluminate: - Aluminium oxide (Al2O3), traditionally referred to as alumina, is the most established of the engineering ceramics. Being strong, hard, chemically inert, and available in tonnage quantities, this material now has a firm commercial standing as an engineering ceramic.

Inorganic Binder:

An inorganic binder is an inorganic ingredient used to bind together two or more other materials in mixtures. Its two principal properties are adhesion and cohesion. Characteristics: Produce strong final agglomerates, permanently bond particles, withstand the rigors of storage, handling, packaging & shipping.
