Pronunciation: [pˈɪɹɐlˌɒla͡ɪt] (IPA) 
Pyrallolite, a mineral composed of sodium, calcium, aluminum, silicon, and oxygen, is spelled /paɪˈræləlaɪt/. The initial sound, /paɪ/, is the same as in "pie." The next two syllables, /ræl ə/, contain the vowel sound in "cat" followed by an unstressed schwa sound. The final syllable, /laɪt/, has the same vowel sound as in "light." The double L in the center of the word is pronounced as a single sound, /l/.
Pyrallolite is a rare and relatively unknown mineral that is typically found as a secondary mineral in hydrothermal veins. It belongs to the pyroxene group and has a unique chemical composition, primarily composed of iron, calcium, and aluminum.
In terms of physical properties, pyrallolite is typically found in either short prismatic or platy crystal habits, and it exhibits a vitreous to pearly luster. Its color can vary, but it is most commonly seen in shades of green, gray, or brown. The mineral has a hardness of approximately 5 to 6 on the Mohs scale, making it relatively resistant to scratching.
Pyrallolite's name is derived from the Greek words "pyro" meaning fire and "lithos" meaning stone, reflecting the crystal's notable high temperature resistance. This mineral is often associated with other minerals such as quartz, albite, and garnet, and is commonly found in metamorphic rock formations.
Due to its rare occurrence and limited availability, pyrallolite does not have significant industrial uses or commercial value. However, it is highly regarded among mineral collectors because of its unique crystal structure and scarcity. Researchers and geologists also study pyrallolite to better understand its formation and the geological processes that lead to its occurrence.
A mineral found in Finland, of a greenish-white colour.
