2319. Marbled Sealing-Wax is made by mixing different kinds of sealing-wax together just as they begin to solidify.
2320. Yellow Sealing-Wax. Mix together 4 ounces pale shellac, 11/4 ounces resin,
2 ounces Venice turpentine, and 3/4 ounce King's yellow (sulphuret of arsenic, or orpiment).
2321. Light Brown Sealing-Wax. Take 71/2 ounces shellac and 4 ounces Venice turpentine; and color with 1 ounce brown ochre and 1/2 ounce cinnabar (red sulphuret of mercury or vermilion).
2322. Blue Sealing-Wax. Take 16 parts mastic, 4 turpentine, 8 mountain-blue, 3 burned selenite. The mountain-blue turns green by the heat of melting the mixture; therefore it is better to use fine indigo, or very fine Prussian blue; but in that case the shellac must be particularly light-colored.
2323. Dark Blue Sealing-Wax. Mix 7 ounces fine shellac, 3 ounces Venice turpentine, 1 ounce resin, and 1 ounce mineral blue.
2324. Green Sealing-Wax. Mix 4 ounces shellac, 2 ounces Venice turpentine, 11/4 ounces resin, 1/2 ounce King's yellow (see No. 2320 (Yellow Sealing-Wax)), and 1/4 ounce mineral blue. Or: 24 parts shellac, 12 mastic, 4 turpentine, 6 verdigris ; colored with a mixture of yellow and indigo.
2325. To Make Perfumed Sealing-Wax. Any fine sealing-wax may be perfumed by mixing 1 per cent, of balsam of Peru, or liquid storax, to the ingredients when considerably cooled. A little essence of musk or ambergris will serve the same purpose. The addition of a little camphor or spirit of wine makes sealing-wax melt easier.
2326. To Improve the Appearance of Common Sealing-Wax. To make common sealing-wax appear to better advantage, the sticks, being still soft, are dipped in the powder of a better quality, and then superficially melted, so as to produce a thin coating.
2327. Soft Sealing-Wax for Diplomas. Take 16 parts yellow wax, 3 turpentine, 1 olive oil; after it is melted, the cinnabar, or other coloring matter, is stirred in the compound.
2328. To Take Proof-Impressions of Seals and Stamps. For this purpose the very best sealing-wax is melted as usual by a flame, and carefully worked on the surface to which it is applied, until perfectly even; the stamp is then firmly and evenly pressed into it. The flame of a spirit lamp is preferable, having no tendency to blacken the wax. A beautiful dead appearance is given to the impression by dusting the stamp, before using it, with a finely-powdered pigment of the same color as the wax; thus, for vermilion sealing-wax, powdered vermilion, etc..
