    • PURPOSE: A silica glass forming mold using a sol-gel process is provided which is able to minimize the stress given to the inside of the gel and effectively prevent the surface of the gel from being damaged when a mandrel is removed from the tube in the process of de-molding. CONSTITUTION: In the silica glass forming mold using a sol-gel process having a tube(21) and a mandrel(22) which is placed in the center of the tube(21), the mandrel(22) is taper-treated and when the diameter of one end of the mandrel(22) is D, the diameter of the other end is D plus or minus delta and the delta is 0.02-0.1% of the length(L) of the mandrel(22).
