The mixture must be used at boiling heat, and after it has been applied, the gilt surface must be varnished over. To Separate the Leaves of Charred Books.-- Cut off the back so as to render the leaves absolutely independent from one another, then soak them, and dry them rapidly by a current of hot air. The leaves will then separate, but must, of course, be handled with extreme care. Japanners' Gold Size.--In gold printing japanners' gold size may, it is suggested, profitably take the place of the size ordinarily used. Powder finely of asphaltum, litharge, or red lead, each 1 oz.; stir them into a pint of linseed oil, and simmer the mixture over a gentle fire, or on a ...
