The correct spelling of the word 'Voltzite' is often confusing to many, owing to its uncommon usage. However, with a basic understanding of phonetic transcription, one can decipher its correct spelling. The IPA phonetic transcription for Voltzite is /ˈvoʊltsaɪt/. This means that the word is pronounced with a first syllable that sounds like "volt," followed by a second syllable that sounds like "site." With this understanding, one can confidently spell and use Voltzite accurately in any context.
Voltzite is a mineral that belongs to the oxide class and is categorized under the tungsten group. It is known for its distinct brown to black coloration and lustrous appearance. Voltzite is composed of various elements, including lead, oxygen, and chlorine, with the chemical formula Pb6V2O7Cl2. It commonly occurs as small crystals or aggregates, often found in association with other ore minerals.
The mineral was first discovered in the lateritic weathering zone of lead and vanadium-rich ores in Bolivia and was named after Ernst Friedrich vom Rath, a renowned German mineralogist. Voltzite has a specific gravity range of approximately 7.5 to 7.7 and a Mohs hardness of 2 to 3, indicating a relatively low hardness.
Despite its limited occurrence, voltzite is of interest to collectors due to its unique crystal structure and attractive appearance. It exhibits an orthorhombic crystal system, characterized by three axes of unequal length that are perpendicular to each other. Voltzite crystals often display a prismatic habit and may be transparent to translucent.
From a geological standpoint, voltzite is considered an important mineral as it is indicative of specific geological environments. Its presence in lead and vanadium-rich ores suggests the presence of unique geological processes responsible for its formation. Understanding these processes can aid in exploring and evaluating potential mineral resources in similar ore deposits.
In conclusion, voltzite is a distinctive mineral with a prominent brown to black coloration. Its chemical composition, crystal structure, and association with other minerals contribute to its significance both in the realm of mineralogy and geology.

The word "Voltzite" has its origin in the name of the German mineralogist Franz Ludwig von Voltz (1805 - 1878). Voltz was known for his contribution to the understanding of minerals, particularly in the field of crystallography. In recognition of his work, the mineral Voltzite was named after him.
