The colouring forehearth technology was developed to allow glassmakers to produce short runs of a wide range of colours without the costs of changing colour in the furnace by adding colour in the form of metal oxides in a low melting point boron based frit.
The colour forehearth technology is very flexible allowing the full range of production in a wide range of colours including container, table ware and cosmetic containers.
Glass Service has developed colouring forehearths in various sizes and lengths, each designed for the specific pull, colour range and production.
Glass Service design and supply the forehearth colouring technology as well as all of the necessary production equipment:
The automatic frit dosing device
The stirrer machine
The control panel
The systems are of strong reliable construction, designed for continuous operation.
The main concepts of our colouring forehearths are: simplicity, flexibility and reliability.
The automatic frit dosing device and the stirrer machine can be easily adapted to a wide range of pull rates and require low maintenance even when operating under heavy working conditions.
Glass Service has designed and provided coloring forehearths to many customers in Italy, France, Turkey, Russia, China, Poland, Morocco and Spain.
