WebObsidian. Rondi: Everyone, meet Obsidian , an igneous rock that from melted rock, or magma. Obsidian is an "extrusive” rock, which means it is made from magma that erupted out of a volcano. If it was an igneous rock that formed from magma underground and did not erupt, it would have been called an "intrusive" rock. WebIn igneous rocks, quartz forms as magma cools. Like water turning into ice, silicon dioxide will crystallize as it cools. Slow cooling generally allows the crystals to grow larger. Quartz that grows from silica-rich water forms in a similar way. Silicon dioxide dissolves in water, like sugar in tea, but only at high temperature and pressure.
