K40 is 100% hand-made, hand-moulded and reduced, i.e. fired in low-oxygen conditions. It has four equally usable sides and a rough, changing surface. Each brick bears the thumbprints of the craftsperson who made it. K40’s deep, dark-brown colour has reddish-brown and burgundy tones. The understated dark areas are due to the red slurry added to the wet clay in the wooden mould. All of the bricks have a slightly sandy surface as well as partially vitrified areas.
