Today we photographed our bricks, the final photo shown above shows the brick iterations in the order we produced them.
Competition was close between bricks 3 and 4 as to which became out final prototype, whilst brick 4 has crisper external corners, the strong internal lines of brick 3 make it the winner. Arguably external crispness is less important in a wall configuration compared to how strong the internal lines of the bricks are, as these are responsible for casting shadows. Weaker internal lines means a lesser change in light and dark over a wall.
Excessive sand appears to be the reason behind weaker internal lines, the 4th brick has more sand stuck to it’s internal face than any other brick.
If we were to improve on the the 3rd Brick, I would expect us to repeat the throwing process with greater force, to ensure all of the clay reaches to the deepest corners of the mould.
