Abstract: A multi dental flask system. The system includes a boot, at least two dental flasks, a sleeve, and a wrench. The boot is affixed to a surface. The at least two dental flasks are stacked one on top of the other. A lowermost dental flask of the at least two dental flasks is non-rotatably received in the boot. The sleeve is replaceably affixed to the lowermost dental flask of the at least two dental flasks and houses the other at least one dental flask of the at least two dental flasks so as to allow the at least two dental flasks to be processed simultaneously. The wrench receives the sleeve and replaceably affixes the sleeve to the lowermost dental flask.
