Everything Grumbacher makes is tested again and again at every stage of its existence, which inspired the name Pre-Tested®. Grumbacher's time-proven formulas are finely tuned through independent laboratory tests as well as hands-on trials by professional artists. They specify the best ingredients available, putting each one through a rigorous selection process. On the factory floor, they sample batches in process and sample the raw material again before shipping their products. And finally, even after our products are in the field, they continue to track batches and test for quality, performance and shelf life.
Flake White - A permanent, very heavily bodied, opaque, warm white. As the most permanent of all whites, Flake White is ideal for heavy impasto applications or where several layers of color must be built up.
Titanium White (Original) - A permanent, heavy-bodied, versatile, opaque, pure white that is neutral in hue. Ideal for all applications where great opacity is required. This is the strongest tinting white.
Titanium White (Soft) - This pigment is permanent, soft-bodied, opaque, non-yellowing and ground in poppyseed and sunflower oils. Also recommended for fluid wet-in-wet techniques.
Zinc White - A permanent, heavy-bodied, semi-opaque, cool, crisp white. Designed especially for brilliant clear tints with all oil colors and excellent for glazing.
