The ceramic colours of the special Collection PR were developed for decorating borosilicate glass.
Temperature range:
580°C - 630°C
The average coefficient of expansion lies within the range of 50 – 300°C at 55x10-7/K and 60x10-7/K. Therefore, the colours of this collection can be applied on tea glasses and coffee pots as well as on laboratory and technical glassware made of DURAN, PYREX or other types of borosilicate glass. Table- and kitchenware made of opal glass can also be decorated with these colours.
The colours of this collection contain lead and cadmium.
