1575. It is impossible to enumerate the variety of articles to the manufacture of which Diaphanie may be successfully applied, as it is not confined to glass, but can be done on silk, parchment, paper, linen, &c., after they have been made transparent, which may be accomplished in the following manner:—
1576. Stretch your paper, or whatever it may be, on a frame or drawing board, then apply two successive coats (a day between each,) of diaphanous liquor, and after leaving it to dry for several days, cover it with a thin layer of very clear size, and when dry it will be in a fit state to receive the coat of varnish and the designs.
1577. Silk, linen, or other stuffs, should be more carefully stretched, and receive a thicker coat of size than paper or parchment; the latter may be strained on a drawing or any other smooth board, by damping the sheet, and after pasting the edges, stretching it down while damp. Silk, linen, and other stuffs require to be carefully stretched on a knitting or other suitable frame.
1578. Take great care to allow, whatever you use, time to dry before applying the liqueur diaphane.
1579. All kinds of screens, lamp-shades, and glasses, lanterns, &c., &c., may be made in this way, as heat will produce no effect upon them.
