    Description and Usage:

     

    Those minerals are mounted in five metal pole respectively,use the corner of those mineral to scratch the gemstone,you will get the hardness according to the nick you scratch,if there is a nick after you scratched,the sample's hardness is lower than the standard hardness pencil;if there is no nick after you scratched,that means the sample's hardness is higher than the standard hardness pencil.

     

    Matters need attention:

     

    1.use the indirect-vision method to estimate the hardness of the sample.

     

    2.find a inconspicuous place,use the talc-l or plaster-2 to scratch the sample,if can't do,that means the sample's hardness is higher than the standard hardness pencil,so pls use the higher pencil to scratch,repetitive operation,if there is a shadow nick,that means the sample's hardness is amoust the same with the standard hardnedd pencil,then use the higher hardness pencil to scratch the gem,if there is a deep nick,means sample's hardness is lower than the standard hardness pencil.so in this way,we can get the hardness of gem or the scope of hardness.

     

    3.when you scratch,don't too heave or too light,just proper vigor.
