The Voynich manuscript is an illustrated codex, hand-written in an unknown script referred to as 'Voynichese.'. [18] The vellum on which it is written has been carbon-dated to the early 15th century (1404–1438). Stylistic analysis has indicated the manuscript may have been composed in Italy during the Italian Renaissance.
Potassium chromium sulfate. Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). Chrome alum or Chromium (III) potassium sulfate is the potassium double sulfate of chromium. Its chemical formula is KCr (SO 4) 2 and it is commonly found in its dodecahydrate form as KCr (SO 4) 2 ·12 (H ...
It seeks to contain information on all inorganic crystal structures published since 1913, including pure elements, minerals, metals, and intermetallic compounds (with atomic coordinates). ICSD contains over 210,000 entries as of December 2020 [update] and is updated twice a year.
The Crystallography Open Database (COD) is a database of crystal structures. Unlike similar crystallography databases, the database is entirely open-access, with registered users able to contribute published and unpublished structures of small molecules and small to medium-sized unit cell crystals to the database.
It is formed by precipitation from hydrothermal fluids, and contains by mass: 16.3% Tl, 47.3% Cu, 2.9% Ag, and 33.6% Se. [2] Crookesite is an opaque, bluish grey to pink toned brown metallic mineral crystallizing in the tetragonal system. It has a Mohs hardness of 2.5 to 3 and a specific gravity of 6.9.
Specimen from California, US; size: 5.9 cm × 3.8 cm × 3.8 cm (2.3 in × 1.5 in × 1.5 in). Cristobalite ( / krɪˈstoʊbəˌlaɪt /) is a mineral polymorph of silica that is formed at very high temperatures. It has the same chemical formula as quartz, SiO 2, but a distinct crystal structure. Both quartz and cristobalite are polymorphs with ...
A crystallographic database is a database specifically designed to store information about the structure of molecules and crystals. Crystals are solids having, in all three dimensions of space, a regularly repeating arrangement of atoms, ions, or molecules. They are characterized by symmetry, morphology, and directionally dependent physical ...
Crocoite is commonly found as large, well-developed prismatic adamantine crystals, although in many cases are poorly terminated. Crystals are of a bright hyacinth-red color, translucent, and have an adamantine to vitreous lustre. On exposure to UV light some of the translucency and brilliancy is lost. The streak is orange-yellow; Mohs hardness ...
