A manufacturing apparatus for a glass article includes a melting furnace as a storage tank, and a measurement device configured to measure a height of a liquid surface of a molten glass stored in the melting furnace. The measurement device includes a nozzle to be immersed from above the liquid surface into the molten glass, a pipe, which is led from an outside of the melting furnace into the melting furnace at a position higher than the liquid surface, and is configured to allow supply of a gas to the nozzle, and a pressure gauge configured to measure a pressure in the pipe or the nozzle under a state in which air bubbles are being generated in the molten glass with the gas supplied from a distal end of the nozzle.

A system for and method of determining process parameters for a gob forming subsystem are disclosed. Upstream sensor data, representing information captured by one or more sensors installed upstream of a feeder of the gob forming subsystem, are obtained. One or more gob forming process parameters are determined as a result of executing an artificial intelligence (AI) model that takes, as input, the upstream sensor data and that generates, as output, process parameter data representing the one or more gob forming process parameters.

A method for capturing and evaluating data on a batch blanket on a glass melt in a cold-top melting tank for the melting of glass includes: providing at least one sensor for contactlessly capturing data on the batch blanket at least at an end of a boom of a charger at which batch is applied to the glass melt; repeatedly capturing and storing (a) data of the batch blanket during operation of the melting tank with at least the at least one sensor, data being captured from at least 10 different positions of the batch blanket, and (2) respectively assigning the data to a position of the end of the boom and/or the at least one sensor; and processing the captured data and compiling a topographic map of the batch blanket.
