Each watercolor pan is hand-poured. Hand pouring pans is incredibly labor-intensive and offers the purest form of professional watercolor half pans. It takes three to four pours over several months of drying to produce each half pan of DANIEL SMITH Watercolor. Found in iron deposits nearly worldwide, Goethite (Brown Ochre) is named after Johann Wolfgang Goethe, the German philosopher, poet, and mineralogist. Our unusually pure pigment is mined in Russia, south of Moscow. Rich and warm, DANIEL SMITH Goethite is a dark tea color in mass tone and washes out to a rich, warm tan. In washes, it displays intriguing granulation, with pools of light and dark in every brushstroke. Like all colors derived from the earth, it is lightfast and permanent; a lasting connection to the planet and the creative forces of nature.
