K41

K41 is 100% hand-made and hand-moulded, with four equally usable sides and a rough, changing surface. Each brick bears the thumbprints of the craftsperson who made it. K41’s contrasting colours range from reddish-brown to shades of burgundy and almost black. Black aggregate is added to the wooden moulds as a lubricant, creating an almost charred look in parts. It also has partially vitrified areas.
