Mathematical tile
The mathematical tile was an external cladding or tile hanging solution that was popular in the 17-1800's in the South of England. The tiles were shaped in such a way that they interlocked and from the outside face resembled a brick facade and were a popular cladding solution for timber frame buildings.
It has been suggested that the tiles were designed as an alternative to bricks as a result of the brick tax introduced by King George III in 1784, however although known as the Brick tax, it actually also covered tiles and so these were subject to the same tax, though unclear if less. It is more likely that the tiles represented a useful solution to dealing with the facade of timber frame buildings in seasde locations, because they were cheaper, simpler and quicker to construct than brick and in many respects as, if not more resistant to weathering.
In areas around the South Coast of England, such as Brighton and Lewes a specific black glazed version of the tile was popular, many examples of which can still be seen today. (image credit Stuart Walsh under CC license)
