If glazed facade elements are described as the „silver bullet“ in the use of facade ceramics, this claim can be further strengthened by the use of effect glazes.

Effect glazes are the „haute couture“ for facades. Now NBK offers a portfolio of glaze finishes that have no boundaries and that can be also expanded at any time by the wishes and demands of architects and building owners.

Effect glazes are not only effective because of their variety of colours, which already goes beyond the portfolio of common glazes. They offer an additional range of colour effects and thus enter the artistic field of architectural ceramics.
