A practical treatise on mechanical dentistry . The writer has, for several years, used with much satisfaction aflask constructed with detached T-shaped bolts fitting accuratelyinto slots or grooves extending continuously from top to bottom ofthe flask, as represented in Fig. 122. The closure of the sectionsbv this arrangement, with the bolts in place, is unerring, and isaccomplished with the greatest facility. It is known as the Im-proved Anchor Flask. Another useful form of flask is that de-vised by Dr. I. N. Broomell, and is represented in Fig. 123. Fig. 124 represents an oblong, or box flas

Another useful form of flask is that de-vised by Dr. I. N. Broomell, and is represented in Fig. 123. Fig. 124 represents an oblong, or box flask, designed for 296 MECHANICAL RUBBER OR VULCANITE BASE. 297 exceptionally large cases, splints for fractures, artificial palates,etc. Whatever flask is used, the entire mass of inclosed rubber shouldbe rendered uniformly plastic, after packing, by subjecting it toeither a dry heat, such as may be obtained with a conveniently con-structed sheet-iron furnace, the baking apartment of an ordinarycooking stove, or any other available means by which a diffused anduniform temperature may be secured, being careful not to overheat;or, if moist heat is employed, by immersing the flask in boiling Fig. 125.
