Rublev Colours Barite (Baryte) is a premium, natural white pigment made from high-quality barium sulfate ore (PW22). Finely ground to a 4-micron median particle size with a high specific gravity (4.4), Barite is valued for its luminous feel, durability, and true inertness—making it a studio staple for both traditional and modern paintmaking.
Why artists choose Barite (PW22)
-
Excellent extender / filler pigment: Use it to adjust body and handling, reduce tinting strength, and build smoother paint films.
-
Ideal for grounds & whites: Especially useful for making white paint and grounds in watercolour, casein and egg tempera, and as an extender in oils and alkyds.
-
Chemically inert & broadly compatible: Unaffected by dilute acids and alkalis; compatible with all pigments and vehicles.
-
Easy to wet out: Mixes readily with oil or water to form a smooth paste (oil absorption: 12 g oil / 100 g pigment).

Source & safety notes
Our Barite is from a natural U.S. source and is stated to not contain heavy metals (industrial coating deposits are selected to be free of toxic metals). While barite is considered extremely insoluble, always handle dry pigment carefully and avoid breathing dust.
