That explains why Capstan uses electric annealing exclusively, because it can be so accurately and perfectly controlled. In case you are not familiar with glassmaking, annealing is a process by which the hot containers formed from molten glass are cooled and heat treated. It's similar to the tempering of steel. Capstan's electric annealing equipment assures the same degree of heat in every nook and corner of the annealing ovens.
