After the Flask has been closed it may be removed from the Oven and placed in avise or a flask-clamp, and allowed to cool gradually and thoroughly, the Oven meanwhilebeing ready for another case. The principle involved in the process of working Celluloid by this method is theproduction, from the evaporation of the water in the plaster, of a moist heat, whichgradually becomes more and more dry as the heat is increased or continued. It has theadvantage over other methods, of driving off any excess of camphor remaining in thecompound, besides admitting of the patching or repair of plates better than by the useof oil or glycerin, or by the ordinary steam apparatus.
