Abstract: In connection with drawing a fiber in a drawing portion of a drawing device having a refractory, oxide component, a method and apparatus provide an environment in the drawing portion that causes active oxidation of a refractory contaminant on a blank. The active oxidation of the refractory contaminant causes it to corrode away during drawing.
