A fixative is a substance that serves to preserve or stabilize a material, particularly in the domain of art and science. In art, a fixative is a liquid solution or spray that is applied to various mediums, such as graphite, charcoal, pastel, or paintings, in order to prevent smudging, fading, or deterioration over time. By binding the pigments or particles to the surface, the fixative creates a protective layer that ensures the artwork's longevity and prevents unwanted alterations. Additionally, fixatives in art also act as a sealant, giving a matte or glossy finish to the artwork, depending on the type of fixative used.
In the field of science, a fixative is a chemical solution used to preserve biological specimens, such as tissues or cells, for further examination under a microscope. It works by halting any ongoing biological processes, preventing decay, and fixing the cells or tissues in their natural state. Fixatives play a crucial role in preserving the structure and morphology of biological samples, allowing for accurate observation, analysis, and scientific research.
Overall, whether in art or science, fixatives serve as a crucial tool to enhance preservation, stability, and longevity. By preventing deterioration, smudging, or decay, fixatives ensure the integrity and quality of artworks or biological samples, enabling further study, appreciation, or analysis.
