Apart from Leopoldo Nobili, who already in 1824 performed his first experiments related to the appearance of Nobili's rings, Leonhard Elsner, Alexander Watt, Antoine César Becquerel (1788–1878) and Rudolf Christian Böttger (1806–1881) also dealt with the electrochemical coloring of metals in that early period.
Tungsten occurs in many alloys, which have numerous applications, including incandescent light bulb filaments, X-ray tubes, electrodes in gas tungsten arc welding, superalloys, and radiation shielding. Tungsten's hardness and high density make it suitable for military applications in penetrating projectiles.
Hemerdon Mine, also known as Hemerdon Ball Mine, Hemerdon Bal Mine and (briefly) previously as Drakelands Mine [note 1] [1] is a tungsten and tin mine. It is located 11 km (7 miles) northeast of Plymouth, near Plympton, in Devon, England.
Scheelite is a calcium tungstate mineral with the chemical formula Ca W O 4.It is an important ore of tungsten (wolfram). Scheelite is originally named after Swedish chemist Carl Wilhelm Scheele (1742–1786).
The Tungsten and Tin Project was Wolf Minerals' core asset. It is located near Plymouth in the County of Devon in the southwest of the UK. At the time, Wolf identified the Hemerdon project as a potentially major new source of global tungsten supply. It acquired the project in December 2007 and has conducted extensive exploration programs and established a large JORC Resource in
Titanium rings are jewelry rings or bands which have been primarily constructed from titanium. The actual compositions of titanium can vary, such as "commercial pure" (99.2% titanium) or "aircraft grade" (primarily, 90% titanium, 6% aluminum, 4% vanadium), and titanium rings are often crafted in combination with other materials, such as gemstones and traditional jewelry metals.
