This is a tablet made of a fine grained, smooth dark stone  upon which needles tipped with specific alloys of silver or gold are rubbed. This leaves a coloured streak upon the surface which can be compared to that produced by the object which is being tested to determine the purity of the metal. Touch needles were part of a goldsmith's inventory. In 1532, the London goldsmith Robert Amadas was reported to have a set of 15 copper needles tipped with gold, a bunch of silver needles and a touchstone. \n\nThis set of needles is signed by P. Salydo, the maker, in 1682. Each needle is numbered to indicate the alloy with which it is tipped. ","physicalDescription":"Copper touch needles tipped with gold of varying alloys, hanging in five groups of twelve from cast copper beaded S-scroll brackets. The groups of needles hang from a silver openwork hemisphere with a cut, chased and engraved floral design. The needles are 'damascened' with their numbers in silver.
