Abstract:
1. A method of stabilizing a column of a viscous liquid material comprising: a. flowing a viscous liquid material from an opening in a vessel to form a column of the viscous liquid material, wherein the viscous liquid material is a precursor material for forming a glass or glass ceramic; b. drawing the column of viscous liquid material vertically downward through an atmosphere; c. drawing the column of viscous liquid material into a passage defined by a stabilizing member and including an inlet orifice and an exit orifice, the channel being disposed about the column of viscous liquid material; and d. wherein a viscosity of the viscous liquid material at the opening is less than 30 kP and a viscosity of the column at the exit orifice of the stabilizing member is at least 10
