Natural fired colours
Single fired glazes
Double fired glazes
The spectrum of natural fired colours ranges from white, sandy, yellow and taupe right up to colours that tend towards grey. There is also an immeasurable range of red tones spanning all the way up to brown and black tones available for selection. All terracotta elements that are produced using TERRART® in this way have been produced with moulded-in colour and using the single-firing method.
However, the beauty of natural ceramics arises out of more than just its colour. Specific tech- niques create surfaces that develop a character that is entirely their own. Creative ideas can thus be implemented impressively. Whether the surface is combed, stripped, sanded or ma- chined in any other way – an experience that is unique both visually as well as haptically is the end result.
Applying a uniform engobe gives our elements an entirely new, coloured character. In terms of the system, the engobes cover a colour spectrum that focuses on subtle colours and permits very special effects that bring pastel colours to mind. This means that specific deco- rative concepts can be brought to life that are fully in keeping with the creative architect’s ideas.
By applying the sintered engobe, surfaces with a metallic structure reminiscent of cast iron are created using metal oxide in the reduction firing technique. Used in the TERRART® façade system, specific impressions and ideas can thus be realised so that unique façade solutions can be found.
As awareness of environmental conservation and sustainability has grown over the years, NBK pays particularly close attention to protecting people’s health as well. This explains why our glazes have been switched over to lead-free formulations. With the single- firing technique, both matt as well as glossy surfaces can be created, as can all the usual effect glazes based on selenium.
