Grumbacher Matte Medium
Matte Medium improves color flow and provides artwork with a matte finish. This allows Matte Medium to be perfectly suited for under-painting or wall painting along with fine art work. With ingredients like poppy oil, balsam and copaiba, this medium is very effective but will not alter the appearance of any color hue. Just mix small amounts with the chosen colors to achieve more control and smoothness with the improved fluidity.
Available in a 2.5 oz. bottle
FLAX art & design is a genuine Oakland institution. Opening their first store in 1938, they're now on their 3rd generation of family ownership and have recently relocated to a beautiful new Downtown location that could best be described as a "toy store for artists." 80 years in and they're still putting art and community front and center. You can visit them at their own site here, or find more of their products right here on Keep Oakland Alive.
