Testing Stones

Gold Testing - Precious Metal Testing Stones

When testing for gold, always suspect that the item could be plated.
Rub the stone over the piece to remove any plate on the item.

Apply the acid as required on the touch stone to test.

Applying testing acid directly on to the metal will discolour the item,
therefore if a piece is returned to the customer there will be no acid
spoil inflicted on to the metal.
(Stone size may vary)

Other Uses:
  • After sharpening your gravers on a sharpening stone use a "Touch Stone" to achieve
    a mirror finish, a better way than using conventional abrasive paper that could rip.
  • Use oil to obtain best results.
