made at Montpellier in France, and is a sub-acetate of copper of a

bright green colour inclining to blue. The least durable of the copper

greens, it soon fades as a water-colour by the action of light, &c., and

becomes first white and ultimately black by damp and foul gas. In oil,

verdigris is permanent with respect to light and air, but moisture and

an impure atmosphere change its colour, and cause it to effloresce or

rise to the surface through the oil. It dries rapidly, and is

exceptionally useful with other greens or very dark colours. In varnish

it stands better; but cannot be considered safe or eligible, either

alone or compounded. Vinegar dissolves it, forming a solution used for

tinting maps, and formerly much employed for colouring pickles, &c.

Italy, used this pigment; and the bright greens seen in some old

pictures are made by glazings of verdigris. It is often largely

adulterated with chalk and sulphate of copper.
