ABSTRACT:
A blank mold sooting process in which a lubricating or detaching layer is formed on the internal walls of the blank mold, by igniting an acetylene flow with piezoelectric electrodes, a voltaic arc generator, or an electrical resistance. The process is performed utilizing, for example, a blow mold and an invert, and the invert can be utilized to transfer a collar from the blank mold to the blow mold.
