Or Masticot Is A Protoxide Of Lead Varying From The Purest And Most





tender straw colour to a dull orange yellow, and known as Light, Yellow,

and Golden Massicot. It has in painting all the properties of white

lead, from which it may be prepared by gentle calcination in an open

furnace. In tint with that pigment, however, it soon loses its colour

and returns to white, probably extracting some carbonic acid therefrom.

If used in an unmixed state, it is permanent in oil under the same

conditions as white lead, but should not be employed in water, on

account of its changing even to blackness by the action of damp or

impure air. It is an admirable dryer, and has much the same effect as

litharge in rendering oils siccative.
