Practical dental metallurgyA text- and reference-book for students and practitioners of dentistry .. . Fig. 9. MELTING METALS. 67 better able to withstand an intense heat, more durableand quicker in its operations than the old pattern, withgun-metal tubes. In case metal should be spilled into theburner, it can be easily taken apart for its removal. Downies crucible furnace, Fig. 10, is especially de-signed for melting metals, such as gold and silver,making dental-amalgam alloys, experimental work, Fig. 10. It is also very useful for brazing, soldering, heating upbridge-cases or metal plates to solder, etc. It has tworemovable rings of different widths, which set on abovethe flaring base to carry the heat up around the crucible,the wide or narrow ring being used, according to the size 68 PRACTICAL DKNTAL METALLURGY. of the crucible; or both rings may be put on at the sametime. It also has a conical-shaped top which can be seton above the rings to confine the heat when it is desiredto fuse any high fusing substance. This furnace can be used for baking continuous-gumwork, or any other porcelain work.
