Within glass production, conditioning systems have the essential task to homogenize the glass as preparation for the forming process. JSJ is providing its customers with tailor-made working ends, forebays, forehearths, and feeder solutions. The necessary thermal and chemical homogeneity is ensured by precise adjustment and control of the glass temperature, as well as specially designed stirrer, drainage, and overflow systems.

Covered forehearth with top electrode heating for production of specific borosilicate- and opal glass:

• no evaporation of volatile components
• perfect glass quality
• temperature distribution in the outlet cross section ≤ ±3K
