Abstract
A porous glass base material sintering method comprising measuring a feeding speed Vf of a porous glass base material and a movement speed Vw of a bottom end of the glass base material; performing a sintering treatment of the porous glass base material presetting, for each feeding distance L of the porous glass base material, a greater-than-1 target value αS (L) of an elongation rate in a straight body portion of the porous glass base material calculated based on a ratio Vw/Vf, and controlling at least one of a temperature of the heating furnace and a feeding speed of the porous glass base material such that a measured value α of the elongation rate of the porous glass base material matches with the target value αS (L).
