Oil Painting Studio Kit

Oil's long open time (days wet) allows seamless blending and glazing that acrylic's fast dry cannot — the luminous skin tones and deep glazes of classical painting are oil's domain. The trade-off is solvent, slow drying, and complexity. Acrylic for speed and learning; oil for the depth and the patience.

The oil-painting rule — each layer should have more oil (fatter) than the one beneath, so the upper layers dry more flexibly and do not crack over the more-rigid lower layers. Start thin (lean, with solvent), build to fat (with oil). Violate it and the painting cracks as it dries. It is the structural rule of oil painting.

Odorless mineral spirits (like Gamsol) for thinning and brush cleaning — "odorless" means low-vapor, not no-vapor; ventilate the room. Rags soaked in drying-oil solvents can spontaneously combust — spread them flat to dry or store them in a sealed metal can of water. Dispose of spent solvent at a hazardous-waste drop-off, never down the drain.

Wipe out the paint, rinse in solvent (a silicoil jar with a cleaning coil), then wash with soap (a masters brush cleaner) and warm water until the suds are white. A dried oil brush is dead; clean them the day you use them, condition them occasionally, and they last years. Oil brushes are an investment worth protecting with disciplined cleaning.
