5. ck Gold plate GENERAL DESCRIPTION OF PROCEDURE To determine that an item is Gold plated non Gold the user of the M24 Gold Tester must take at least two different readings one reading of a surface which has not been erased or filed The reading of the erased or filed surface will be lower if the metal underneath is not gold To be sure the metal underneath is not Palladium see the section on TESTING FOR PALLADIUM The M24 Gold Tester will read as NOT GOLD if a sufficient area of non Gold is exposed to the liquid but the un erased or un filed Gold plate exposed to the liquid does have some effect on the reading this is why point 2 of the following section under PRECAUTIONS is important When testing for heavy Gold plate it may be necessary to use a fast drying lacquer or material such as a clear fingernail polish The area to be tested must be coated with the lacquer and allowed to dry Next make a file mark in the center of the coating deep enough to expose the base metal Then test the exposed base metal with the M24 Gold Tester Do not allow the Testing Solution to touch any part of the Gold that has not been coated PRECAUTIONS 1 When testing the un erased or un filed portion be sure that the test area has been relatively unaffected by wear Flat or thin Gold plated items will tend to be worn at the edges If it is difficult not to expose a worn area when testing an un erased or un filed area the user may
