Ingredients
- an ounce of litharge
- one pound of linseed oil
- a pint of this dryer is required
Method
- Vitreous oxide of lead (litharge), is of no other use in painting than to free oils from their greasy partieles, for the purpose of communicating to them a drying quality.
- Red litharge, however, ought to be preferred to the greenish yellow: It is not so hard, and answers better for the purpose to which it is destined.
- When painters wish to obtain a common colour of the ochrey kind, and have no hoiled oil by them, they may paint with linseed oil, not freed from its greasy particles, by mixing with the colour about two or three parts of litharge, ground on a piece of porphyry with water, dried, and reduced to fine powder, for 16 parts of oil.
- The colour has a great deal of boay, and dries as speedily as if mixed with drying oil.
- Siccitive oil.
- Boil together for two hours on a slow and equal fire, half an ounce of litharge, as much calcined ceruse, and the same of terre d'ombre and talc, with one pound of linseed oil, carefully stirring the whole time.
- It must be carefully skimmed and clarified.
- The older it grows the better it is.
- A quarter of a pint of this dryer is required to every pound of colour.
