Rome stair balusters are to be painted two coats nnis.i-ing sreen and bronze. The first coat should be lead-colour paint, and when this is dry give a coat of bronze green made from drop black (about one-third) and yellow ochre (about two-thirds). Thin with benzoline, adding a few drops of terebine as a drier.. Put the bronze in a pint pot, cover it well with turpentine (which will extract the verdigris), and let it stand for six or seven hours, after which the turpentine should he thrown away and fresh turpentine added Varnish the balusters, and when the varnish is nearly dry dip a piece of plush velvet in the bronze, and apply to the projecting points of the balusters. This should be done while the varnish is tacky, so that the bronze may dry with the varnish.
