INDESTRUCTIBLE LABELS. 



Many methods of making indelible labels 

 have been suggested. Writing on the glass 

 with a mixture of fluoric acid and pigment 

 is satisfactory, but the following will be 

 more generally convenient : Waste cellu- 

 loid roll films should be cleaned from the 

 photographic film and cut into slips of the 

 sizes required for the labels. The writing 

 may be done on ordinary white paper, but 

 slips of gelatino-chloride paper from which 

 the silver salts have been fixed out are 

 much better. Cement the thin celluloid 

 film on the label, and securely fasten that 

 to the glass. For this purpose nothing is 

 better or more convenient than the well- 

 known Diamond cement sold for mending 

 glass and china. Once set, it is impervious 

 to heat and damp, and though expensive as 

 commonly sold, is not difficult to make 

 when a quantity is required. The formula 

 is to dissolve one ounce of soft gelatine 

 in 3 ounces of water, and to add 1^2 

 ounces of spirits of wine and 40 grains of 

 gum ammoniacum triturated in y 2 an ounce 

 of water. Finally, add 36 grains of mastic 

 dissolved in |4 ounce of strong alcohol, and 

 store the cement for use. When required, 

 it must be dissolved by placing the bottle 

 in hot water. It should be used both to 

 attach the celluloid to the label and that 

 to the bottle. Practically nothing will de« 

 stroy such a label, and a wet cloth will at 

 all times keep it clean,— Photographs
