Water filter, Norfolk Island dripstone

In 1851 the Lieutenant-Governor of Tasmania, Sir William Denison, who was also responsible for the administration of Norfolk Island, sent a dripstone made in that tiny remote penal settlement to London.

Object Statement

Water filter, dripstone, limestone, made at Norfolk Island, Australia [1825-1890], used by Captain James Little, Moore Park, New South Wales, Australia

Physical Description

The dripstone comprises a deep round stone bowl, with oversize square rim that allows it to be supported in a wooden frame with the lower portion of the bowl hanging clear of the frame. The bowl is carved from calcarenite, a form of limestone with a high content (around 50 percent) of sand-sized grains; pores in the stone allow water to percolate through under gravity. In use, water intended for drinking was placed in the bowl and allowed to drip into a vessel sitting below it, leaving sediment behind and so improving the water's clarity and taste. The current timber frame was made by the museum to replace the original louvered wooden frame, whose base had perished by the time it was donated.
