vidriado

Vidriado is a Spanish term that translates to "glazed" in English. It refers to the process of applying a vitreous coating to ceramic, pottery, or other materials. This coating, often made from glass-forming minerals, is fired at high temperatures, creating a hard, impermeable, and often decorative surface.

The purpose of vidriado can be functional, enhancing durability, preventing staining, and making the object easier to clean. It can also be purely aesthetic, adding color, shine, or intricate patterns to the surface. Historically, vidriado has been employed across many cultures for a wide range of applications, from everyday tableware and tiles to architectural elements and artistic sculptures.

The composition of the glaze can vary significantly, influencing its color, texture, and melting point. Common ingredients include silica, fluxes like feldspar or borax, and colorants such as metal oxides. The application methods also differ, ranging from dipping and brushing to spraying. The firing process is crucial, as it fuses the glaze materials into a glassy layer that adheres permanently to the underlying substrate. In modern contexts, vidriado continues to be a vital technique in the production of ceramics, contributing to both the utility and beauty of countless objects.
