Forehearth Stirrer

Capability Summary

Forehearth stirrer assemblies are used to homogenize the glass in a forehearth or gathering bay by mechanically stirring the glass and breaking up any cord present in the system. They are used very effectively in lead crystal glass with up to 30% lead, particularly in reducing the effect of Zirconia cord. Stirrers are essential in a color forehearth to mix the frit with the base glass to ensure an even distribution of the coloring materials.
