Historical information
There is a slight ridge ridge along the side where the wet clay has been pushed up between the bricks as they have been stacked. Wooden press moulds were used to form the brick and lead shaped markers were used to brand a frog in the brick. The frog is the hollow in the centre of the face of the brick. This centre helps the bricks to adhere in construction.
