«PARAFFINE:»

«Rendering Paraffine Transparent.»—A process for rendering paraffine and its mixtures with other bodies (ceresine, etc.) used in the manufacture of transparent candles consists essentially in adding a {508} naphthol, particularly beta-naphthol, to the material which is used for the manufacture of the candles, tapers, etc. The quantity added varies according to the material and the desired effect. One suitable mixture is made by heating 100 parts of paraffine and 2 parts of beta-naphthol at 175° to 195° F. The material can be colored in the ordinary way.

«Removal of Dirt from Paraffine.»—Filtration through felt will usually remove particles of foreign matter from paraffine. It may be necessary to use a layer of fine sand or of infusorial earth. If discolored by any soluble matter, try freshly heated animal charcoal. To keep the paraffine fluid, if a large quantity is to be handled, a jacketed funnel will be required, either steam or hot water being kept in circulation in the jacket.

«Paraffine Scented Cakes.»

Paraffine, 1 ounce; white petrolatum, 2 ounces; heliotropin, 10 grains; oil of bergamot, 5 drops; oil of lavender, 5 drops; oil of cloves, 2 drops. Melt the first two substances, then add the next, the oils last, and stir all until cool. After settling cut into blocks and wrap in tin foil. This is a disseminator of perfume. It perfumes where it is rubbed. It kills moths and perfumes the wardrobe. It is used by rubbing on cloth, clothes, and the handkerchief.

«PASSE-PARTOUT FRAMING.»

It is hardly correct to call the passe-partout a frame, as it is merely a binding together of the print, the glass, and the backing with a narrow edge of paper. This simple arrangement lends to the picture when complete a much greater finish and a more important appearance than might be anticipated.

In regard to the making of a passe-partout frame, the first thing is to decide as to the width of the mount or matt to be used. In some cases, of course, the print is framed with no mount being visible; but, unless the picture is of large size, it will usually be found more becoming to have one, especially should the wall paper be of an obtrusive design. When the print and mount are both neatly trimmed to the desired size, procure a piece of clear white picture glass—most amateur framers will have discovered that there is a variance in the quality of this—and a piece of stout cardboard, both of exactly the same dimensions as the picture. Next prepare or buy the paper to be used for binding the edges together. This may now be bought at most all stationery stores in a great variety of colors. If it is prepared at home a greater choice of colors is available, and it is by no means a difficult task with care and sharp scissors. The tint should be chosen to harmonize with the print and the mount, taking also into consideration the probable surroundings—brown for photographs of brown tone, dark gray for black, pale gray for lighter tones; dark green is also a good color. All stationers keep colored papers suitable for the purpose, while plain wall papers or thin brown paper answers equally well.
