gessót

Gessót is a term sometimes used to refer to a pale, often chalky, white pigment or a white undercoat applied to surfaces, particularly in artistic or decorative contexts. It is derived from the Italian word "gesso," which means gypsum. In art, gesso is commonly used as a primer for canvases and panels, providing a smooth, absorbent surface that prepares the material for painting. This traditional primer is typically made from a mixture of gypsum or chalk and glue.

The purpose of applying gesso is to seal the surface and create a uniform ground, preventing the paint from soaking unevenly into the material. It also adds brightness and opacity, which can enhance the vibrancy of subsequent layers of paint. While traditional gesso is made with animal glue, modern acrylic gesso is a popular alternative, offering greater flexibility and ease of use, as it is water-based and dries quickly.

Beyond traditional art applications, the term "gessót" might also be informally used to describe a white coating applied to walls or other surfaces for decorative or preparatory purposes, similar to a white primer. The specific composition and application can vary depending on the intended use, but the core concept revolves around a white, often matte, finish that serves as a base or a visual element.
