These enamels are intended mainly for the decoration of tumblers, but are also used for cosmetic and perfume bottles.

Chemical Composition

Colors in this System contain lead and cadmium.

Intermixable Color Range

These colors all contain lead and cadmium and are therefore intermixable in any proportion.

Colors from different Systems should not be mixed.

Our technical service teams also offer a full custom-color matching service, including special decorative effects.

Expansion Coefficient (C.o.E.)

Avg. C.o.E. measured on the basic frit System is 90 (± 4).10^-7K^-1.

Exception is cobalt-blue VS 302, which contains a Co-based flux and has a C.o.E. close to 100 (± 4).10^-7K^-1.

We do not recommend this system for multi-trip bottles, or bottles which have to withstand strong internal pressures.

Recommended Firing Conditions

From 580^oC to 600^oC (1075-1110^oF) in a cycle of 1hr-1.5hrs or more, with a soaking period of c.10 minutes

Chemical Resistance

Norm EN 1388-2 (tests on the basic flux system in laboratory conditions)

-          lead release is < 25mg/dm² of the decorated surface.

Exception is VR 302 cobalt blue, with a lead release of c. 60mg/dm² of the decorated surface.

-          Cadmium release is < 3mg/dm² of the decorated surface.
