1657. Spirits and oil of turpentine; oil and varnish colors; seed-lac, white and transfer varnishes; oil of almonds; spirit of wine; a flat and a round brush, and a towel.
The Varnishes.—The seed-lac and white varnishes.
1658. The Transfer Varnish.—Take five ounces of the best spirit of wine, add four ounces of the purified Venice turpentine to it, and an ounce of picked mastic tears; put them into a bottle, shake constantly until the mastic and turpentine dissolve, and in a few hours it will be fit for use, but improves by keeping.
1659. To Transfer to Glass.—Procure a piece of the best crown-glass, as near as possible in size and shape to the print to be transferred, varnish it over with a mixture of equal parts of spirits and oil of turpentine, and lay the print on the glass, beginning at one end, and pressing it gently down with a towel in every part in proceeding to the other.
1660. If this is not done carefully, vesicles of air will be admitted between the paper and glass, and mar the effect. After pressing the print down with the towel, it is to be set aside to dry, which will take some time, varying according to the state of the atmosphere.
