Abstract
An elongated tank body of a glass melting apparatus defines a melting region adjacent its inlet end, a refining region downstream, a conditioning zone adjacent its outlet end and an intermediate zone leading from the refining region to the conditioning zone. The intermediate zone and conditioning zone are substantially narrow relative to the refining region. Flow control means physically slows up the forward flow of the upper levels of glass out of the refining region and into the narrower zones. The refining region and intermediate zone are sufficiently deep for forward and return flow of molten glass to take place. A step is located at the upstream end of the conditioning zone which has a raised base providing a shallow conditioning along which molten glass flows toward the outlet with substantially no return flow.
