Abstract:
1. A method comprising: generating a molten foamed glass comprising molten glass and bubbles entrained therein and/or a layer of glass foam on a top surface thereof in a melter, the melter comprising at least a floor and a sidewall structure defining an internal space sufficient for containing the molten foamed glass; transferring at least a portion of the molten foamed glass into a downstream apparatus positioned downstream of the melter, the downstream apparatus comprising at least a floor and a sidewall structure defining an internal space sufficient for containing a non-flowing or flowing stream of the molten foamed glass; and determining density as a function of distance from a structural feature of the molten foamed glass in either the melter, the downstream apparatus or both, using one or more electromagnetic (EM) wave-based sensors.
