Mathematical tile

Source: Wikipedia, the free encyclopedia.

Mathematical tiles nailed to wooden planks, overlapped and mortared to give the appearance of a brick surface

Mathematical tiles are tiles which were used extensively as a building material in the southeastern counties of England—especially East Sussex and Kent—in the 18th and early 19th centuries.[1] They were laid on the exterior of timber-framed buildings as an alternative to brickwork, which their appearance closely resembled.[2] A distinctive black variety with a glazed surface was used on many buildings in Brighton (now part of the city of Brighton and Hove) from about 1760 onwards, and is considered a characteristic feature of the town's early architecture.[1][3] Although the brick tax (1784–1850) was formerly thought to have encouraged use of mathematical tiles, in fact the tiles were subject to the same tax.[4]

Name

The precise origin of the name "mathematical" is unknown.

attributive names include "brick", "geometrical", "mechanical", "rebate", "wall", or "weather" tiles.[5] According to Christopher Hussey, "weather tile" is an earlier more general term, with the true "mathematical tile" distinguished by its flush setting.[10] In 18th-century Oxford "feather edge tile" was used.[11] While "mathematical tile" is now usual, Nail considered it a "pretentious" innovation, preferring "brick tile" as an older and more authentic name.[12]

Usage and varieties

9 Pool Valley, Brighton has a black tile façade of 1794.

The tiles were laid in a partly overlapping pattern, akin to roof shingles. Their lower section—the part intended to be visible when the tiling was complete—was thicker; the upper section would slide under the overlapping tile above and would therefore be hidden. In the top corner was a hole for a nail to be inserted. They would then be hung on a lath of wood, and the lower sections would be moulded together with an infill of lime mortar to form a flat surface.[13] The interlocking visible surfaces would then resemble either header bond or stretcher bond brickwork.[1][2][14][15] Mathematical tiles had several advantages over brick: they were cheaper,[1] easier to lay than bricks (skilled workmen were not needed),[16] and were more resistant to the weathering effects of wind, rain and sea-spray, making them particularly useful at seaside locations such as Brighton.[17]

Various colours of tile were produced: red, to resemble brick most closely; honey; cream; and black. Brighton, the resort most closely associated with mathematical tiles, has examples of each. Many houses on the seafront east of the

Gault clay to make them.[18]

A 1987 count of surviving mathematical tiles in English counties found the most in Kent (407 buildings), followed by Sussex (382), Wiltshire (50), Surrey (47), and Hampshire (37 including the Isle of Wight).[19]

Black glazed tiles

Black glazed mathematical tiles—as seen here at 44 Old Steine—are a characteristic feature of Brighton's 18th-century architecture.

The black glazed type is most closely associated with the Brighton's early architecture:

The Lanes, Brighton's ancient core of narrow streets.[3]

Quaker meeting house of 1784.[31]
