Process used to Identify Minerals - 911 Metallurgist

When trying the weight of a piece of mineral in the hand, it is natural to think of its size; but its shape should also be noted; because what is really being done is to estimate the weight as compared with the bulk. A thin, flat specimen is apt to give the idea of largeness, while a thick or...
