Abstract: A bell positioning apparatus for glass tubing manufacturing includes a bell and a support connected to the bell. A bell positioning apparatus is attached to the support and configured to move the support and the bell with at least three degrees of freedom. The bell positioning apparatus includes a platform, a platform frame, and one or more frame legs. A frame leg dimensional stability apparatus maintains a temperature variation within 6.5° C. per meter of distance between each frame leg for an extended period of time, e.g. 4 hours.

Abstract: A method for analyzing a glass melt composition, in the manufacture of glass articles, includes sampling a gas composition comprising at least one gaseous species generated from the glass melt composition during a melting operation by taking a plurality of measurements of the gas composition over a period of time. The method also includes analyzing the sampled composition to determine an amount or concentration of the at least one gaseous species in the gas composition as a function of time.
