Gold lace, spangles, clasps, knots, etc, may be brushed over with the following composition: 1 1/2 oz. shellac, 1/2 dr. dragons' blood, 1/2 dr. turmeric root ,• digest with strong alcohol, decanting the ruby-red coloured tincture thus obtained. After coating with this composition, a warm flat-iron is gently brushed over the objects, so as to heat them only very slightly. Gold embroidery can be similarly treated. Silver lace or embroidery may be dusted over with the following powder and well brushed. Take alabaster, and strongly ignite it, and whilst still hot place it in corn brandy; a white powder is thus obtained, which is fit for use after heating over the flame of a spirit lamp. It should be dusted on from a linen bag.
