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.
Claims12
A blank mold sooting process for use on a glass making apparatus, said process comprising steps of:
- (a) depositing a lubricating/detaching layer:
- (i) on the internal walls of a blank mold which includes a first open end and a second open end at least substantially opposite the first open end
- (ii) by igniting an acetylene flow having a flow rate with piezoelectric electrodes, thereby producing a flame, and
- (b) directing the ignited acetylene flow such that the flame:
- (i) flows into the first open end of the blank mold,
- (ii) extends through the blank mold, and
- (iii) leaves the blank mold through the second open end.
