Each brick is stacked and sorted by hand into batches after being oil fired in down-draught batch kilns. Firing can be controlled to produce unique colours, ranging from blues, purples, red/blues, blue clinkers, red, autumn tones, through to grey browns and coffee. The pressed bricks can also feature surface face cracking, variegated colour highlights and strove bar marks, when required.

To produce the bricks, natural clay is extracted from Krause Bricks’ local quarry. They use no additives or artificial colouring. All colours are derived by the careful blending of clay stocks and variation in firing techniques.
