Obsidian is primarily composed of silica (SiO2), which is the main component of volcanic glass. It also contains various trace elements such as aluminum (Al), iron (Fe), magnesium (Mg), sodium (Na), potassium (K), and calcium (Ca), depending on its specific composition and the conditions under which it formed. These elements contribute to its color and properties, making obsidian typically black, brown, or green, among other variations.
