Lead White (also known as flake white or Cremnitz white) is an opaque white that is smooth and brushes long in the direction of the brushstroke. The consistency straight out of the tube is creamy, slightly ropey yet retains its shape as you manipulate it while being soft yet sculptural.
Our lead white is made with pale linseed oil and basic lead carbonate (made according to modern processes) without stabilizers (e.g. stearates, waxes, etc.) or fillers to alter the characteristics of the pigment. As a result you get higher pigment volume concentration (PVC) than other brands of lead white (flake white)-as high as 50%. This means most brands of flake white do not weigh nearly as much as Rublev Colours 50 ml tube. Yet, Rublev Colours Lead White is not overly stiff and mixes well with all other oil colors.
Lead white is the most common white found on the old masters' palette. Lead pigments have been made artificially since Antiquity, although health concerns of lead poisoning has greatly diminished its role in paint today.
