DESCRIPTION: Prep the tile you want your image on with some oil. Any kind of clear oil is fine--cooking oil, massage oil, linseed oil, etc. Load up a rag with a bit of oil and rub it on the tile. Get the tile well coated with oil, then wipe off the excess so the surface is not slick. The oil on the tile will help the oil paint stick better, and will give you a more vibrant color.
