Oil paint is a type of paint that uses oil as its medium. The oil is mixed with pigment to create an emulsion, which can be spread on a surface and dried to produce a durable, glossy finish. Oil paints are slow-drying, allowing artists more time to blend colors and make adjustments to their work. They also have excellent adhesion and flexibility once dry, making them suitable for a wide range of applications from fine art to industrial coatings.
