Pair of Boltwoodite on Gypsum Matrix from China – Stabilized
Combined Weight: 20 grams
Locality: Dongchuan Kunming Yunnan China
Boltwoodite is a rare mineral belonging to the uranyl silicate hydrate group. It is named after Charles Boltwood, an American chemist. Boltwoodite typically occurs as small, prismatic to tabular crystals or as coatings on the surface of other minerals. In terms of its composition, Yellow Boltwoodite contains uranium, calcium, silicon, oxygen, and water molecules. Its formation is associated with hydrothermal processes involving the leaching of uranium-bearing minerals and subsequent precipitation in fractures and cavities. Gypsum, a common evaporite mineral, often serves as a host rock for Yellow Boltwoodite crystals.
These specimens were stabilized with Paraloid B-72, a commonly used conservation material in the field of mineral preservation, providing excellent protective qualities for long-term conservation. The stabilization process infuses the specimen with an acrylic polymer resulting in a more rigid specimen that won’t decompose, or fall apart over time.
