Our forehearth color concentrates and pearls enable the production of a vast range of color options usually produced in the tank. Almost all colors that can be produced in the tank can also be produced by forehearth colors. Forehearth coloring can also be used to modify glass that is colored in the tank, such as the conversion of dead leaf green to antique green for wine bottles. 

Forehearth color pearls are a new generation of lead-free in-glass coloring technology that deliver a vibrant color range.  Blues greens, brown, purples, pinks and blacks are produced using cobalt, chrome, copper, nickel, manganese, selenium and other rare earth elements in various combinations and concentrations to create a large palette of colors. 

Special glass compositions such as reduced soda lime, amber, opal, borosilicate and leaded glass can also be colored using forehearth colorants .

All Ferro forehearth color products are lead-free and fulfill EU regulations for RoHS and REACH compliance.


Our forehearth color concentrates and pearls deliver many advantages over the traditional method of in-tank coloration.

 

Improved Productivity
Machine time is reduced during the conversion of a large tank from flint to colored glass production. 

Greater Flexibility
Glass colors can be changed quickly and easily for short runs of special colors in the forehearth.

 

Reduced Energy Consumption
Colored glass produced with forehearth color concentrates and pearls can be produced in large production tanks, which have lower energy requirements per ton of produced glass.

This eliminates the needs for special production runs in smaller tanks, which require more energy for production runs.

 

Lower Inventory
Cost reduction can be achieved with inventory reduction as smaller lots of colored glass can be produced on demand, eliminating the need to produce and store large runs of colored glass.

 

Lower Shipping Costs
Instead of focusing colored glass production in one plant, forehearth coloring can be used at all production facilities, providing more flexibility in shipping options.
