This low-melting color series predominantly is used for decorating:
– lighting and decorative glass,
– beer and other drinking glasses (for drinking glasses, it is necessary to keep 20 mm of lip and rim area free of the paints)
– cosmetic vials, ampoules and more.
The paints are also suitable for earthenware (beer mugs) and wall tiles. Test first.
Also, the decoration of aluminum enamel (such as toasters and nonferrous metals) is possible with Universal Glass colors.
The paints are generally intermixable. Only the three precious metal containing colors – PR144 Purple, P7036 Violet, P7044 Purple red – are not suitable for mixing with most of the other paints. These should only be mixed with white, black or blue. Further tests are necessary.
For mixing with black, Ruger & Gunzel also recommends RGF 330 black.
To brighten the colors, use Flux FL 231.
