This pigment has excellent covering and hiding power and is widely used in paints.
The "Inside Out" faces, by contrast, were unknown, and in their anonymity they implied a hidden power.
Its commercial use actually stopped much earlier; because of its low index of refraction (1.94), white lead had been replaced by titanium dioxide, which is more than eight times as efficient in hiding power.
Carbon black, any of a group of intensely black, finely divided forms of amorphous carbon, usually obtained as soot from partial combustion of hydrocarbons, used principally as reinforcing agents in automobile tires and other rubber products but also as extremely black pigments of high hiding power in printing ink, paint, and carbon paper.
Egyptian blue requires coarse grinding to maintain its colour, showing poor hiding power [155].
Using a white paint was thought to be inferior in hiding power compared with orpiment.
As pigments, they show good hiding power and siccative properties when used in oil [246].
Over 170 "action points" have been proposed to improve the WHS setting, including minimising light pollution, advising on development and removing or hiding power lines and "unsightly buildings".
The lime technique improves the hiding power, even if the final colour becomes greyish, as well as when the pigment is mixed with animal glue.
