Is Gamblin Rich Gold oil paint okay to use in outer layers in my paintings? I paint indirectly and will use it for small areas such as on a bird’s feathers or parts of leaves, etc. I don’t know anything about these metal paints and hoping they’re durable paints. I bought it on a whim. In case this is relevant, I only use a little linseed oil as my medium. Thank you for starting this site for artists!
Using Rich Gold on the top layers of a painting is fine. Rich Gold is formulated by suspending bronze powder in an oil modified alkyd resin binder. Adding a small amount of linseed oil is fine, but do not thin with solvent-rich (lean) mediums or solvent alone, as this will under-bind the metallic pigment and cause it to discolor. It will retain its color well when the pigment is remains suspended in its binder. I hope this helps. Scott Gellatly, Gamblin Product Manager
Great question, Brian. In short, it’s the appearance of the resulting paint layer. The mica powders look like mica powders. Bronze, and aluminum look like metal. Encasing the pigments in alkyd resin protects them from moisture and oxidation-related changes.
Thanks to all of you for your answers.
Thanks Scott, Just curious, what was the benefit with using bronze powders in this instance rather than going with one of the many of tarnish-proof mica pigments available today?
