Enamel Raw Materials
Enamel Raw Materials include enamel frit, pigments, opacifiers and clays that are blended into a sprayable slurry called “slip.”

Enamel raw materials include enamel frit, pigments, clays and milling additives.
- Enamel Frit:
Frit used in porcelain enameling is a ceramic composition formulated from borosilicate. This is a type of glass known for having very low coefficients of thermal expansion, thus making it resistant to thermal shock and less subject to thermal stress. After fusing in a special furnace the material is quenched to form a glass. Quenching or high-pressure cooling consists of high-pressure air blasts to the surface of the glass that cools the outer surface more quickly than the center. As the center of the glass cools it remains in tension while the outer surfaces go into compression—thus giving the glass strength.
- Enamel Pigments:
Pigments are used during the slip blending process for creating a desired color. They are an insoluble colored substance used as a mineral base to be added to the frit material.
Pigments can be used to create extremely tight control over color variation in the finished product. Leading manufacturers use pigments in their daily inspection and slip evaluation of color quality for assurance that production matches customer expectation.
- Opacifiers
Opacifiers are substances added to a material in order to make the ensuing system opaque. Additives, such as titanium dioxide (TiO2), ensure that the glass is not transparent and can cover up a darker ground coat or base coat. Titanium dioxide is an important component for maintaining high quality standards and assurance over time that the slip will perform as if it has just come out of the mill.
- Clays
The primary purpose of clays for use in porcelain enameling is as a suspension agent. In order to maintain consistency in application, clays are used to maintain a standard for how the material sprays and adheres to the substrate. Additionally, clays serve a purpose in the developing bubble structure, which is critical to the bonding process.

Professional BBQ Manufacturer in North America Mr. Jacky .Carl
We bought from Ferro(USA) before, and we started to try Nolifrit 10 years ago, then I never going to change supplier again. Nolifrit enamel frit quality stable , and their technical support without any delay. The most important is that they help us to save more than 20% enamel raw material cost, which makes us more competitive in the market.
