Five generations of chemists in the Blockx family have been working since 1865 to perfect the Blockx Oil Colors. Today they are still ground on stone rollers and mixed with poppyseed or linseed oil, and no additives or fillers whatsoever.
Color Swatches created using heavy application/medium application/50% tint and were applied on acrylic primed canvas (7 oz) material.
