These authentic Chinese drawing and painting inks allow for stability and re-solubility. The inks are intense black straight from the bottle and create different values when mixed with water. Mix with Chinese watercolors for even more interesting effects. The 180ml bottles have a convenient lid that allows the cap to come off the side of the larger cap for increased flow control. When used on absorbent papers such as rice paper, Golden Black ink shows as gold with a black outline as the black in absorbs into the paper and the suspended gold coloured particles are kept on the paper's surface. On less absorbent papers the ink will show more subtly. Ink will look black with a gold shimmer on non-absorbent paper
