ОПИСАНИЕ

Art with a big A. The homogeneous mixture of a precise proportion of manganese dioxide in the clay results in a light-grey brick. The different types of sand provide colours that vary from white to grey, interspersed with light grey and dark shades in defined proportions, in which the white deposits are clearly present. Through sintering Nelissen obtains the light gray brick with black and brown spots. These hand-moulded facing bricks are made from Löss from Limburg, extracted from the plateau of Kesselt in the Meuse valley and revalued with raw materials from the Volcanic Eifel. The facing brick (non-perforated) is sanded on five sides and provided with a possible oblong sloping groove on one flat side. The structure has a rough appearance with fine and irregular grooves in the sandy surface. The baking process is done in a gas-fired tunnel kiln under slightly reducing atmosphere.

Fassaadikividel (perforeerimata) on viis liivataud külge ja ühel küljel võib esineda piklikke sooni. Kivi struktuur on krobeline, peenete, ebaühtlaste vagudega liivasel pinnal. Kivid valmivad tunnel-gaasiahjus, kergelt vähendatud õhuvooluga.

ЦВЕТ

Täpselt määratletud kogus mangaanoksiidi, ühes punakashalli saviga, annavad tulemuseks kivi helehalli värvi. Erinevat tüüpi liiva kasutamise tulemusena, varieerub kivi värv valgest hallini, helehallide ja tumedate varjundite ja valgete terakestega. Kuumpressimise teel saavutatakse kivi helehall, mustade ja pruunide varjunditega värv.
