REDOX® tarnishing colours

In contrast to engobes or glazes, the special composition and individual effects of tarnishing colours REDOX® make them a completely separate type of product.

In 1972, Martin Grothe was experimenting in the lab when he succeeded in making the tarnishing colour now with the registered trademark ‘REDOX®‘. This product finishes many surfaces of quite different kinds and makes the results as unique as a fingerprint. After firing, tarnishing colours REDOX® bond permanently to ceramic bodies, penetrating deep inside them.

The colours can be mixed together and can be applied on top of one another to achieve quite individual colour effects depending on the thickness of the application. Dry scattering through a fine sieve also leads to outstanding results. The colours can be fired in both reducing and oxidizing atmospheres, with a huge variety of firing colours resulting. Tarnishing colours REDOX® can also be used to outstanding effect in fast firing applications in combination with special engobes ENGOSYN®. They are of outstanding quality and quick to process.

REDOX® grades can be supplied for a huge variety of kilns and firing curves at temperatures between 980°C and 1320°C. They are supplied in powdered form and after preparation with water, can be centrifuged, sprayed, poured, immersed or painted on in suspension. A very recent development is the ability also to supply tarnishing colours REDOX® in the form of a slurry.
