Dr. Martin’s Hydrus 1oz Ultramarine

Dr. PH Martin’s Hydrus Fine Art Watercolours are lightfast, brilliant, and concentrated. They are non-toxic, transparent, and house in a glass bottle. This liquid product delivers the same brilliance and permanency as traditional tube watercolours. Made from the finest artist pigments, Hydrus Watercolours can be blended and intermixed while still maintaining the transparency and luminosity of the colours As they are already in a liquid suspension, you cannot do "dry brush" techniques with them.
