EBORACUM confined to mosaic work: it is likewise good in dyeing, as yielding a fine green tincture. As to red ebony, called also grenadilla, we know little of it more than the name.
The cabinet-makers, inlayers, &c. make pear tree and other woods pails for ebony, by giving them the black colour thereof. This some do by a few washes of a hot decoction of galls; and when dry, adding writing ink thereon, and polishing it with a stiff brush, and a little hot wax; and others heat or burn their wood black.
