Material and Production

Answers to frequently asked questions relating to material and manufacture.

Can a ceramic surface alter once it has been manufactured?

No. A ceramic item cannot be altered after firing without applying considerable external forces.

There is a hole of approx. 6 mm in size on the side of the floor-standing toilet (cascade or washout-flushing variant)?

This is a vent hole and thus relates to the production process. Behind this hole is a cavity from which the air has to escape during the firing process.

What are the properties of the ceramic material?

High mechanical strength, unchanging material, non-ageing, glass-hard sealed surface.
UV-resistant, heat- and cold-resistant, colourfast, corrosion-proof, resistant to fire and burning cigarettes, abrasion- and scratch-proof (EXCEPTION: Wondergliss), dimensionally stable, odourless, tasteless.
