About Volcanic Glass
Volcanic glass, any glassy rock formed from lava or magma that has a chemical composition close to that of granite (quartz plus alkali feldspar). Such molten material may reach very low temperatures without crystallizing, but its viscosity may become very high. Because high viscosity inhibits crystallization, a sudden cooling and loss of volatiles, as when lava extrudes from a volcanic vent, tends to chill the material to a glass rather than to crystallize it.
Geologically ancient glasses are therefore very rare, and most glassy rocks are of Paleogene age or younger (less than 65.5 million years old). There is good reason to believe that glassy rocks were abundant in ancient geologic time, but nearly all of these have since devitrified. Devitrification commonly begins along cracks in the glass or around large crystals and may spread outward until eventually the entire mass has been converted to fine crystals of quartz, tridymite, and alkali feldspar.
Characteristic of many natural glasses is a streaked or swirly structure that consists of bands or trains of crystals and crystalline bodies. This structure is believed to have been formed by the flowage of viscous lava. Some flow structures consist of alternating bands of different-coloured material; in others, layers of bubble-free glass alternate with highly vesicular glass.
Metaphysical Properties
Volcanic Obsidian is truth-enhancing. A strongly protective stone, it forms a shield against negativity. It blocks psychic attack and absorbs negative energies from the environment. Obsidian draws out mental stress and tension. It stimulates growth on all levels, urging exploration of the unknown and opening new horizons. Brings clarity to the mind and clears confusion. Helps you to know who you truly are. Obsidian dissolves emotional blockages and ancient traumas. Promotes qualities of compassion and strength.
Volcanic Obsidian aids the digestion and detoxifies. It reduces arthritis pain, joint problems and cramps. Warms the extremities.
If you are looking for fluorite, quartz, citrine or amethyst, this is not it.
