Abstract: The present invention relates to a heating furnace for heating a porous preform made of fine particles of highly pure quartz glass for an optical fiber. The furnace is comprised of a cylindrical furnace body, a heater installed in the furnace body and a muffle tube installed inside the heater to separate a heating atmosphere from the heater. The muffle tube is made of highly pure carbon and is coated with a gas impermeable carbon. The furnace prevents contamination of the preform with impurities and has a long life.
