No substance combines better with salts of copper, than sugar. Sugar, put into the bowl of a tobacco pipe, and placed in the fire, burns fiercely, and is converted into caramel. This, poured on to a plate, slightly smeared with butter, to prevent its sticking, hardens on cooling; and is used for colouring brandy, vinegar, gravy, porter, coffee, &c. Stearine must be scraped very fine from a composite candle.

It is impossible to powder shellac sufficiently fine, by hand; and, twenty years ago, it could not be procured. About that time the drug-grinders, finding a demand for it, submitted it to the action of the stamping mills, (mechanical pestle and mortar), and now it can be obtained at most shops. Chertier mixed it with salt; melted the two together; powdered the mixture; and washed out the salt. Such process is needless now. It is useless, unless as fine as wheaten flour. Page, of 47, Blackfriars Road; and Chubb, of 29, Old Street, St. Lukes, London, supply it.

If powdered nitrate of barytes, and shellac crushed by being hammered in a bag, are mixed together, and melted in a pipkin, over the fire, the mixture, when cold, may be reduced to a powder in an iron mortar, with patience. Take Number 6. Weigh out 21 parts nitrate of barytes, and 2 parts of coarsely powdered lac; melt them together; when cold, powder them; and add the other substances in proper proportion. Shellac may be melted with nitrate of strontian, in the same way.
