THE WHITE SAND TRADE
A painting has come to light showing workers collecting white sand from the cliff to the north of Alum Bay, under Headon Warren, dated 1748. The image has prompted a renewed interest in an often undervalued West Wight resource that supplied the glass industry for over a century.

The above detail from the painting shows the white sand being dug out of the cliff and loaded into boats, for transfer to a ship in the bay. It would have then been taken around to the Sand House at Yarmouth for storage. From there, this scarce material would be shipped to glass manufacturers throughout Britain and Ireland.
By the end of the 17th century, sand had begun to replace flint as the major material in glass making. Glass makers required materials with a minimum iron content, as this gave the clearest glass. Fine white sand met this need but it was uncommon, with fewer than a handful of sources in Britain.
The Urry family owned the rights to the sand. They were already supplying the glass industry with white 'pipe' clay, to make the crucibles in which the glass was melted, so they had the connections to take early advantage of the developing trade. In addition to the Sand House, there was also a Clay House, located towards Norton. The Island's white sand and clay was also used in the making of Chelsea ware, the first English porcelain. The only record giving the volume of white sand shipped out of Yarmouth comes from the mid 19th century, when it averaged around 3,600 tons per annum.
The Sand House is one of the Island's earliest remaining industrial buildings. It is listed as 18th century and appears to have no narrower date-range. It may have been preceded by a more modest building serving a similar purpose. It is a substantial structure and represented a considerable commercial investment. The ensuing years saw the Urry family flourish in West Wight, doubtless partly due to the wealth created through their trade with glass manufacturers.
| Yarmouth's white sand trade would have probably been familiar to some glass making regions in Europe that would otherwise know little or nothing of the Isle of Wight. Venice was the world-renowned centre for glass. This 1776 Venetian map of England shows limited interest in the Island, except for the location of Yarmouth.
