INDIAN RED, is a colour of a body; yet is useful for a back-ground for flowers, at a distance, being used with gumwater.
There is also an earth brought from the Isle of Wight, which has been found to mix extremely well with gum-water; tho' it being of a viscous nature, it requires less gum than most other colours, and as it is naturally fit for use, without grinding, and is viscous, so' it will, without doubt, mix with oil, as well as with water.
There is one thing very extraordinary in this earth, i. e. that if you rub a deal-board with it, it makes it exactly of the colour of mahogany wood, and stains it so deep, and with so much strength, that it is hard to get it out with washing.
And tho' the earth is very dry, yet it has not been able to be got out of papers, in which it has been carried in a pocket.

INDIAN WOOD, call'd also Jamaica and Campeche wood, is taken out of the heart of a large tree, growing plentifully in the isles of Jamaica, Campeche, &c. Itis used in dying; its decoction is very red: and it has been observ'd, that putting some of this decoction into 2 bottles, and mixing a little powder of Alum with the one, it will become of a very beautiful red, which will hold; the other in a day's time becoming yellow, [] both bottles were stopp'd from the air alike; and if a little of the same decoction were expos'd to the air, it would become as black as ink, in the same space of time.

BLACK IVORY, is only Ivory burnt, and drawn into a leaf when it is become black. It is ground with water, and made up into little cakes, or troches, and is used by the painters.

To dye IVORY white. If Ivory be yellow, spotted or coloured, lay it in quick lime, and pour a little water over it, letting it lie for 24 hours, and it will be fair and white.
