the building of the old forge, built at the end of the 19th century, was converted into offices. Our traditionally burned clay bricks in size 250x120x65mm was used for reconstruction in this project. The common solid clay brick , they we produce, is made with using old machinery. And this is cause, that our brick is not perfect like modern architectural clinker. Our common brick has chipped edges, scratches on the surface and other typical features that characterized bricks produced in the 19th century for the needs of industrial architecture.
