Glasses could be seen as the remnants of the liquid that facilitated growth of well-order crystals from the gas phase by the VLS growth process. Based in the chemical (major and trace element) composition of all glasses we have revealed a surprising property of them: they do not show the signature of crystallization of the minerals they are associated with.
