Graining Grounds.
Pollard Oak.—The ground colour is prepared with a mixture of Oxford ochre, Venetian red and white lead in proportions, to form a rich buff; or white lead, chrome yellow and vermilion may be used.
Knotted or Root of Oak.—This ground is exactly the same as the above.
Birch.—The ground is prepared with white lead, a little Oxford ochre and a little Venetian red, of which latter, however, only sufficient must be used to make a very light buff colour.
Mahogany.—The ground colour is prepared with the best Venetian red, yellow ochre and a little white lead (or orange chrome may be substituted for the yellow ochre). If it is desired to increase the brilliancy of the colour, substitute vermilion for Indian red. If a light ground is required use the same colours as above, adding more white. The addition of a little vermilion will increase the richness of the colour.
Rosewood.—The ground colour is mixed in the same manner as above described for mahogany, but a little burnt Turkey umber and Victoria lake is added.
Satinwood.—A little Oxford ochre added to white lead gives the proper ground for this wood.

Walnut.—The ground is prepared with white lead, Venetian red and Oxford ochre, with a small quantity of burnt Turkey umber, but not so much as to destroy the appearance of the other colours and make them poor. Neither red nor yellow should be in excess, but all should be toned down with the umber. Although this colour may look dull when mixed, it is only a relative dullness, and it will shine out brightly enough when grained and glazed.
