In tile production, the application of glazes and engobes is essential to impart specific aesthetic and functional qualities to the finished product. These surface layers define the tile appearance, enhance its technical properties, and make it suitable for various environments and conditions of use. BAAN Minerals will help you choose the right ceramic minerals for your glazes and engobes!

What is a Ceramic Glaze?

The glaze represents the final layer applied to the tile and determines its aesthetic appearance and surface protection. It can vary in terms of opacity, gloss, texture and color, offering endless design possibilities. In addition, glazes protect the tile from stains, scratches and abrasions, making it more durable and suitable for even the most demanding environments, such as bathrooms and kitchens.

The composition of glazes can vary widely, but generally includes:

• Silica and feldspar:to form a strong glassy structure.
• Metal oxides: such as titanium oxide, chromium, iron, and cobalt, which impart specific hues and shades.
• Functional additives: such as matting agents or antimicrobial agents, to improve surface properties.

The choice of glaze type depends on the desired effect, the level of protection required, and the conditions under which the tile will be used. For example, a glossy glaze will look more elegant but less scratch-resistant than a matte one, which is ideal for environments subject to wear and tear.

What is an Engobe?

Engobe is a coating applied directly to the surface of the tile body before final decoration or glazing. Its main function is to create an intermediate layer between the tile body and the glaze, improving adhesion and unifying the base color.

Engobes are generally composed of:

• Colored or white clays: which even out the base of the tile and improve its aesthetics.
• Kaolin: a clay mineral that facilitates adhesion and improves thermal resistance.
• Metal oxides and other pigments: to adjust color and improve aesthetic properties.

The application of engobe not only improves the adhesion of the final glaze, but also helps prevent surface defects such as cracks or color variations during firing.

Conclusion

The combined use of glazes and engobes represents one of the most refined and technical practices in tile production, allowing for an aesthetically pleasing and functionally durable product.
