What purpose does engobe serve in ceramics?

Engobe serves the purpose of providing decorative color and improved texture to ceramics. It is a type of coating made from clay mixed with water and various colorants, applied to the surface of greenware or bisque ware before firing. The primary function of engobe is to enhance the aesthetic appeal of the piece, allowing artists to create intricate designs, patterns, and a smoother surface finish.

While engobe might contribute to the texture of the clay surface, it's essential to note that the primary intent is to achieve a visual effect. Engobes can vary in composition and can be adjusted to achieve different colors and textures, making them versatile tools in ceramic art. Other options refer to structural integrity, thermal durability, and chemical composition, which are not the primary functions of engobe but rather aspects relevant to the overall material properties of the clay or glazes used in ceramics.
