Gloss, or shine, refers to the reflective quality of a surface that allows it to bounce light. This characteristic can be seen in various materials, such as glass, metal, and paint. A glossy surface often appears smooth and polished, enhancing its visual appeal and making colors appear more vibrant. The level of gloss is measured on a scale, with higher gloss levels indicating a more reflective surface. Glossy finishes are commonly used in products like furniture, automobiles, and cosmetics to create an attractive look. However, high gloss can also highlight imperfections, making surface preparation important in achieving a flawless finish.
