The way of laying bricks in various styles, there was if I remember correctly called Flemish bond, English Bond, Header bond.
The main one that you see on the majority of buildings is Running or Stretcher Bond.
The various Bonds probably to suit what was being built way back.
The type of brick used varied a lot. Those used for a house not very strong but those for a chimney stack very very strong.
I would expect these days that there are very very few brickies that can lay the more complicated Bonds or even know of them.
I wonder the type and Bond they use in furnaces or kilns.
