Ferro Forehearth Colors
Ferro Foreharth Color Frits

Ferro offers a wide range of forehearth colorants available as frits, pearls and concentrates. Forehearth coloring can also be used to modify glass colors 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 dust-free in-glass coloring technology

These compacted materials are specially formulated to provide a large range of in-glass color possibilities for premium glass packaging used in perfume bottles, cosmetics packaging, spirits bottles, glass tableware, beverage bottles and architectural glass. 

Special glass compositions such as reduced soda lime, amber, opal, borosilicate and lead-containing glass can also be colored using forehearth colors.

Forehearth color pearls are a new generation of dust-free in-glass coloring technology that deliver a vibrant color range of blues greens, brown, purples, pinks and blacks that 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, similar to those colors produced by concentrates. 

We also offer environmentally friendly options including nickel-free black forehearth colors for bottles and tableware as a concentrate/frit mixture that allows low feed rates for highly intense colors at a reduced cost.  Our chromium-free forehearth colors are available as frits, pearls and/or concentrates.

Forehearth color frits used in the production of high-quality glass with specific colors.
Ferro forehearth color frits can be used particularly when glass manufacturers operate with small forehearths. Fast smelting behavior and chemical properties close to state of the oxidation-reduction of the glass enables the production of high-quality glass with specific colors.
UVA colors provide UV protection of bottle contents for extended shelf life of beer bottles and glass cosmetic containers.
Available as feeder frits or pearls to produce commercial quantities of fluorescent glass that fluoresce under UVA and laser light. These colors are ideal for beverage bottles, cosmetic bottles and tableware.
All Ferro forehearth color concentrates pearls and frits are heavy metals free, fulfill food contact regulations as well as 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.


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. 

Ferro forehearth color concentrates, pearls and frits are widely used in many industries and applications.
