2 TERRART®. The art of the surface. NBK gives many buildings that feature complex architec- Natural Colors ture throughout the world a striking appearance with TERRART® and special surfaces. By using the suspended, construction, more and more creative planners and developers with a flair for unique solutions are setting their mark on façades that are works of art in their own right. Building on the supporting structure, façade ceramics that are the product of craftsmanship and that cannot fail to fill people with wonder and awe are revealed. In addition to the shape, the aspect that allows architects...

TERRART ® Natural Colors 5.01-0 ■ 6.01-0 ■ 6.02-0 ■ 7.01-0 ■ 7.02-0 7.03-0 ■ 8.01-0 ■ 9.04-0 ■ 9.05-0 ■ 9.11-0 Choice of NBK natural colors The application of a microstructure, of the unfired ceramic ware, and its colouring and shading after firing depends on mineral admixtures, their grain sizes, the firing level and firing procedure as well as the organic material content. In this way, a large number of fired colours can be achieved; their effect is strengthened by the ease with which the surface can be structured in its natural character. The spectrum of natural fired...

The technique of profiling in troughs and crests, in identical or different widths also signals individuality based on the matt ceramic surface. The effect on the surface can also be created by incorporating specific oxides and causing sporadic areas to "blossom" so that they are set apart from the rest of the surface. Gazprom Track and Field Stadium, St. Petersburg, Russia The beautiful world of textures. However, the beauty of natural ceramics arises out of more than just its colour. Specific techniques create surfaces that develop a character that is entirely their own. Creative ideas can...

Las Gaviotas Santander / Spain Architect: Santiago Fdez. Elizondo The pale charm of Engobes. Applying a uniform coloured slip layer, known as the engobe, gives NBK ceramic 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 decorative concepts can be brought to life and the mechanical and chemical resistance of the ceramic carrier material is also increased. The coating creates a slip layer, the ceramic substructure is...

Single fired processes By applying the sintered or reduction fired engobe, surfaces with a metallic structure reminiscent of cast iron are 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. Trianglen, Malmo, Sweden Architect: FOJAB Arkitekter Project: East Street, New York USA Architect: FX FOWLE Single fired finishes. NBK Keramik procures the raw material, clay, predominantly from the clay deposits in the Westerwald region. On site, the clay is prepared using...

Glazes. Welcome to the world of colors. The use of glazes is commonly regarded as the supreme discipline in the field of creative fagade ceramics. With the double-firing technique, fagade elements of the highest quality, particularly thanks to the edge glaze created by this additional process, can be created. In addition, the glaze has a particularly brilliant, expressive colour effect. Our strength lies in the development of customer-specific and extraordinary fagade variations in collaboration with architects in order to bring their boldest visions to life by means of material innovation, design collaboration...

Double fired glazes Haven Point, South Shields, Great Britain Architect: LA Architects Double fired glazes for brilliant effects. With the double-firing technique, façade elements of the highest quality can be created. This makes it possible to cut the shard after the single-firing and to glaze the resulting clean edges during double-firing. In addition, the glaze has a particularly brilliant, expressive colour effect. The wide range of opportunities for designing with glazes permit transparent glazes as well as opaque, nontransparent glazes. As vitrifiable enamels, melting at below 1,200˚ oxides...
