Oil paint is a sort of fairly slow paint that is made up of pigment-suspended particles in a drying oil, most frequently linseed oil, that is applied to the canvas. When a solvent such as oil or white spirit is added to the paint, the viscosity of the paint can be changed, and varnish can be applied to enhance the glossiness of the dried oil paint coating. https://pentoink.com/product-category/school-supplies/arts-crafts/complete-painting-kit/oil-paint/
