Madder, a root of a plant, much used by dyers, to make the most solid and rich red-colour.

It is common enough; but generally comes from Holland, and if it is good it is red; 'tis finer than Brazil, and before you use it, it must be finely powdered, to give the better colour.

To extract a tincture of Madder for lake.
This is done by the same method as is done for extracting a lake from Brasl, and will produce a fine colour, which make into troches, drying them, and it will be a perfect lake, and very fine for use. See BRAZILE and LAKE.
