A method for dyeing a glass stream whereby the stream is heated electrically during upward flow, thereafter passed horizontally with a free surface formed atop the stream, adding color frits dyes or the like to the horizontal stream, mechanically agitating the stream during subsequent vertical flow

A method for dyeing a glass stream whereby the stream is heated electrically during upward flow, thereafter passed horizontally with a free surface formed atop the stream, adding color frits dyes or the like to the horizontal stream, mechanically agitating the stream during subsequent vertical flow and flowing the stream thereafter upwards for further treatment or processing.

A method of treating a glass stream for dyeing and refining the glass in said stream which comprises the steps: a. heating the glass stream while flowing in a vertical upward flow by applying electrical energy to at least two electrodes disposed one above the other in said vertical upward flow causing a rising glass stream above said electrodes, b. thereafter passing the stream with a free surface horizontally while supplying dyes, color frits or a pre-dyed glass stream to said free surface of said glass stream at a point directly above said electrodes within said vertical upward flow to prevent freezing of the glass when said dyes, frits or stream are added, c. subsequently flowing the stream vertically downwards with mechanical agitation through a passage having a circular cross-section, the force of agitation being opposite the flow of the glass stream, and d. thereafter flowing the stream upwards for further processing or treatment.
