Rough Rock for Lapidary Ref: IntroRough
Rough rock does not photograph very well and so to indicate texture, colour etc. we have shown cut stones mostly made from our rough stock. Some of this material is available in cut form and is detailed in our printed catalogue.
If the third digit of the code is '0' (i.e.??-0??) then the material will generally be supplied in tumble-polishing size (mostly less than 3cms) but may still require further reduction in size by breaking with a hammer (Wrap stone in sacking to prevent flying 'chips' and also wear protective eye glasses). If the third digit of the code is a '1' (i.e. ??-1??) then the supplied material will be larger pieces suitable for cutting with a diamond saw.
HARDNESS;........
Hardness: use a simple 'scratch’ test to determine the approximate hardness of a stone. A stone which can be marked with a pen-knife, but not with glass, must have a hardness somewhere between 5 and 51/2.
Finger nail. 21/2
Penny 3
Broken glass 5
Pen-knife 51/2
(Hardness is shown in ‘Mohs’ units: 10 is hard down to 1 soft.)
