Yellow is a bright colour, reflecting the most light of any after white.

There are divers yellow substances that become white upon wetting, and drying them again several times at the sun; as wax, linen cloth, &c.

The same bodies, if they be already white, and continue a longtime in the air, without being wetted, turn yellow.

Paper and ivory, apply'd near the fire, become successively yellow, red, and black. Silk when turn'd yellow is whitened with the fumes of sulphur.

Yellow in Dying is one of the five simple and mother colours. For the finest yellows they first boil the cloth or stuff in alum and pot-ashes, and give the colour with goud.

Likewise turmeric gives a good yellow, tho' not the best. There is also an Indian wood that gives a yellow colour, bordering on gold. There is another sort of yellow made of savoury, but this is inferior to them all.

With yellow, red of madder, and that of goat's-hair prepar'd with madder, are made the gold yellow; Aurora, thought-colour, Macarate, Isabella, chamoise colour, which are all casts or shades of yellow.

Painters or Enamellers make their yellow of masticote, which is ceruss raised by the fire, or with oker.

Limners and colourers make it with saffron, French berries, orcanette, &c.
