Fixative

A Fixative is a substance that is used to preserve or stabilize biological specimens, artistic works, or laid-down media. In art, it serves to enhance the longevity of drawings and pastels by preventing smudging or fading. In biology, fixatives preserve the structure of tissues and cells for microscopic examination. Various fixatives may include alcohols, formaldehyde, or specialized chemical compounds tailored for specific applications.
