The subsurface of the brick is dark-metallic. On the handmoulded brick a light grey to white top layer/coating is applied based on a cement mixture. The colour scheme is nuanced. The colour may change in humid conditions, and after drying out the cement coating will get its true colour. The colours shown are a near…
The brick has a grey base. The colour is obtained by a second firing of the bricks in a low oxygen environment. This process can generate light shadings.
The brick has a red base, and the hues vary from burgundy colour to purple with blue violet shades. These shades are obtained through sanding with reddish brown, granular, moist sand and various melted oxides in accurately defined proportions.
The brick has a pink base, and the colour variations show pastel hues ranging from orange-red to purple-red alternated with yellow and blue-grey shadings in accurately defined proportions.
he homogeneous mixture of accurately pre-defined proportions of manganese oxide with grey-red baking lössial clay is responsible for the black colour of the brick. The colour ranges from mainly charcoal to pitch-black with blue shades. Through sintering of the brick, the different nuances of colour are obtained.
he brick has a red base, and the hues vary from burgundy colour to purple with blue violet shades. The shading is obtained from a mixture of lössial clay with reddish brown, granular and moist sand and various melted oxides in accurately defined proportions.
The brick has a red base, with colours ranging from orange-red, bright-red to violet. The red shades are obtained by using natural sands with varying baking colours. The darker shade on the facing brick is obtained by means of coal-sintering.
The brick has a grey base, with colours ranging from silver grey, beige grey to mouse grey. The different structures are the result of sawdust and white, fine-grained sand. Through sintering of the brick, the different nuances of colour are obtained. The melting process of additives during the baking process causes irregular glazing on the…
