To stain and polish teak to represent rosewood, dissolve one pennyworth of Bismarck brown in lpt. of hot vinegar and water (equal parts). With this, brush over the article once or twice. When dry, wipe over with " red oil," which is made by steeping 2 oz. of alkanet root in 1/2pt. of raw linseed oil. The work is then ready for polishing. As teak is a hungry wood, to gain good, results a grain filler should be used. Mix finely crushed dry whiting into a creamy paste with turps, colouring it to match the wood by adding Venetian red and vegetable black or lampblack. Rub well in in order to fill up the grain. Wipe off clean, leaving the surface of the wood free from paste, and polish in the usual way, adding Bismarck to the polish to give a reddish tinge-, it a darker tone is desired, a trace of black may be add'd.
