So it isn’t surprising that simpler techniques need to be used carefully in order to get the best results; and sometimes, they too fail. Finally, while this Key should help the collector correctly identify many minerals, it won’t work all the time. Fortunately, both structure and composition affect certain physical properties. It is through the proper use of these properties that minerals can reliably be identified. The best physical property is one that will give a unique result for a mineral and will always give the same result, again and again, for any and every specimen of that mineral. The General Properties of Matter:1. Mass: very common to all matter. Mass does not change unless divided or removed to a body of matter.2. Weight: it depends in the attraction of the pull of ...
