Ferro Neantichizat cu scobitura
Description
The facade bricks (non-perforated) have five sand covered sides and one side with possible oblong groove. The structure looks relatively smooth with some machining marks in the surface. The baking process takes place in a gas-heated tunnel oven under slightly reduced atmosphere. The homogeneous mixture of accurately predefined 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. The colours shown are a near reflection of reality.
