Aftersealing, the heated portion is cooled gradually by holding it inthe luminous flame until it is blackened. The sealing of hardglass tubes may be facilitated by placing a brick or tile near theflame in such a position that the heat will be reflected. If one 60 GENERAL PART is in possession of a cylinder of oxygen, it may be attached to the blast-lamp in place of the blast. At the high temperatureof the illuminating gas-oxygen name, the sealing may be effectedwith great ease. In many cases the operation is rendered difficult by the vapoursof the substance attacking the glass, or by the decomposition ofthe substance with the evolution of troublesome products likecarbon, iodine, etc. Under these conditions, the tube is notdra Note About Images Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original work. |
