Instructions on making crystoleum paintings are here given. Procure a pair of convex cabinet-size crystoleum glasses, costing about 9d., from any artists' colourman, together with sable brushes and the usual oil colours, megilp, palette knife, etc. Trim the photograph until it is a little smaller than the glass, which, after cleaning, should be well brushed over on the concave side with starch paste. Press the wetted photograph into close contact, and work out the creases by rubbing from the centre to the margins with the bowl of a spoon. This rubbing should be continued - re-wetting the photograph if necessary - until all shiny spots or air bubbles are removed. When dry, rub away nearly all the paper with sandpaper, finishing off with pumice powder. The picture may next be rendered transparent by the use of 2 parts of Canada balsam to 1 part each of white wax and paraffin wax or, preferably, poppy oil. Or clearine, which is a preparation sold for this purpose, may be used. The colours, thinned with megilp and rendered opaque by mixing with white, are laid on the glasses. The delicate and sharp touches are placed directly on the film, and the deeper and bolder work is done on the second glass.

A strip of paper should be pasted all round the edges of the front glass so that the two glasses may be kept from absolute contact. A piece of cardboard is then glued to the back of the picture, and the two glasses being placed together are bound round the edges with paper. The paper may also be removed by rubbing whilst damp, but this method is very risky. Considerable trouble may be saved and more even results obtained by using " Novitas " stripping P.O.P. The film strips readily on placing in warm water, and may be transferred to any article (previously coated with a strong solution of gum arabic) by lifting on a sheet of parchment and stroking out air bubbles as before mentioned. Eastman's transferrotype can also be used for the same purpose.
