摘要

Process for controlling the quality-determining parameters of a glass bath comprises optically measuring the mixture covering and settling, the thermally active heat sinks and heat sources; comparing as set values or in serial control as guide parameters; and adjusting by means of fuel supply, fuel distribution, additional heating power or addition of bubbling. Preferred Features: A differentiation is made, pixel by pixel, between a mixture and a glass, preferably by color weighting, in an image section of a furnace chamber camera. A regulator circuit regulates the degree of coverage of the mixture at the top of the regulation hierarchy.
