Pure Color - Pigment Numbers: PB 29
ASTM Class 1 - Excellent Light-fastness.
Pigment will not change for 100+ years
A safe, synthetic variation of the original pigment derived from Lapis Lazuli. The full bodied, pure, and bright color is shown by pulling the paint out transparently. This pigment leans slightly toward the violet side so it is the perfect pigment for mixing purples and makes lovely greens. Ultramarine Blue mixes well with Phthalo Blue however it this mix you will notice the vast difference in the mixing strength between the two pigments. Ultramarine Blue mixes beautiful colors but is a weaker pigment so you will need more of it to overcome a powerful pigment and see the hue shift. Sapphire Blue is a combination of Phthalo Blue + Ultramarine Blue + Carbon Black + Titanium White.
Heritage MultiMedia Acrylics are a water based non toxic resin acrylic. The binding system contains a 360º coating agent that protects the pigment and improves the overall lightfastness of the color. Dry as needed with a hair dryer and clean up with soap and water.
Heritage MultiSurface Sealer and Varnishes contain UV inhibitors to further protect surfaces. This is especially important when working with delicate papers in decoupaged designs.
For Acrylic techniques, use with water. Out of the tube, they have an approximate drying time of 20 minutes depending on the humidity level in a room.
For Global techniques (oil emulation), use with Extender Medium. By evaporating the water out of the paint and replacing it with Extender you can add hours to the drying time.
