Gold - Wikipedia

Gold is the most malleable of all metals. It can be drawn into a wire of single-atom width, and then stretched considerably before it breaks. Such nanowires distort via formation, reorientation and migration of dislocations and crystal twins without noticeable hardening. A single gram of gold can be beaten into a sheet of 1 square metre (11 sq ft), and an avoirdupois ounce into 300 square feet ...

Mining in Cornwall and Devon - Wikipedia

The intrusion of granite into the surrounding sedimentary rocks gave rise to extensive metamorphism and mineralisation. As a result, Cornwall was one of the most important mining areas in Europe until the early 20th century. It is thought that tin ore (cassiterite) was mined in Cornwall as early as the Bronze Age.[citation needed] Over the years, many other metals (e.g. lead and zinc) have ...

Tin - Wikipedia

Tin is a chemical element with the symbol Sn (from Latin: stannum) and atomic number 50. Tin is a silvery metal that characteristically has a faint yellow hue. Tin, like indium, is soft enough to be cut without much force. When a bar of tin is bent, the so-called "tin cry" can be heard as a result of twinning in tin crystals; this trait is shared by indium, cadmium, zinc, and frozen mercury.
