Show Glue which will Unite even Polished Steel. A Turkish receipt for a cement used to fasten diamonds and other precious stones to metallic surfaces, and which is said to unite even surfaces of polished steel, although al-though exposed to moisture, is as follows: fol-lows: "Dissolve five or six bits of gum mastic, each of about the size of a large pea, in as much spirits of wine as will suffice to render it liquid. In another vessel, dissolve as much isinglass, previously pre-viously softened in water, as will make a two-ounce vial of strong glue, adding two small bits of gum-arumoniac, which must be rubbed until it is dissolved. Then mix the whole with heat. When it is to be used, set tho vial in boiling water. |
