With this décor the colours are melted into the glaze at 1000 degrees C. Here the glaze softens and the décor sinks into it, thus making colour and luminosity indestructible. It is scratch- and wear-resistant. However, gold decors are not totally scratch resistant by virtue of their natural material properties. This décor was tested by the Rosenthal GmbH Institute for material technology (IWT). It is dishwasher safe.
With this décor the colours are burnt onto the glaze at a mini-mum temperature of at least 750 degrees C. The use of robust colours achieves such a strong lesion with the glaze that the dishwasher is most unlikely to do any damage to the décor. Dishwasher tests in the Rosenthal GmbH Institute for material technology (IWT) have proved the excellent durability of the décor. The service can be washed in the dishwasher economy cycle (55 degrees C). Please pay particular attention to the instructions of the dishwasher and detergent manufacturers on the suitability of the their products.
With this décor the appearance of the porcelain or its artistic design are of main concern. The dishwasher safety rules play a deliberately subordinate part here. The use of high quality colours and their subtle application therefore forbid dishwasher cleaning. This décor was tested by the Rosenthal GmbH Institute for material technology (IWT). This porcelain must be washed only by hand.
This porcelain can safely be used in the microwave.
