Abstract
A method for drawing silica fibers utilizing an electrical resistance furnace includes the steps of heating a preform so that it begins to flow forming a fiber; pulling the fiber from the furnace; and flushing the preform and the fiber within the furnace with counteracting inert gas flows, the gas flows protecting the preform and the fiber from contamination. Apparatus used with the above-described method is also disclosed.
