MetalA metal (from Ancient Greek μέταλλον métallon 'mine, quarry, metal') is a material that, when freshly prepared, polished, or fractured, shows a lustrous appearance, and conducts electricity and heat relatively well. Metals are typically ductile (can be drawn into wires) and malleable (they can be hammered into thin sheets). These properties are the result of the metallic bond between the atoms or molecules of the metal. A metal may be a chemical element such as iron; an alloy such as stainless steel; or a molecular compound such as polymeric sulfur nitride.
OreOre is natural rock or sediment that contains one or more valuable minerals concentrated above background levels, typically containing metals, that can be mined, treated and sold at a profit. The grade of ore refers to the concentration of the desired material it contains. The value of the metals or minerals a rock contains must be weighed against the cost of extraction to determine whether it is of sufficiently high grade to be worth mining, and is therefore considered an ore.
Minoan civilizationThe Minoan civilization was a Bronze Age culture which was centered on the island of Crete. Known for its monumental architecture and its energetic art, it is often regarded as the first civilization in Europe. The Minoan civilization developed from the local Neolithic culture around 3100 BC, with complex urban settlements beginning around 2000 BC. After 1450 BC, they came under the cultural and perhaps political domination of the mainland Mycenaean Greeks, forming a hybrid culture which lasted until around around 1100 BC.
TinTin is a chemical element with the symbol Sn () and atomic number 50. A silvery-coloured metal, tin is soft enough to be cut with little force, and a bar of tin can be bent by hand with little effort. When 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 mercury in its solid state. Pure tin after solidifying presents a mirror-like appearance similar to most metals. In most tin alloys (e.g. pewter) the metal solidifies with a dull grey colour.
British MuseumThe British Museum is a public museum dedicated to human history, art and culture located in the Bloomsbury area of London. Its permanent collection of eight million works is the largest in the world. It documents the story of human culture from its beginnings to the present. The British Museum was the first public national museum to cover all fields of knowledge. In 2022 the museum received 4,097,253 visitors, an increase of 209 per cent from 2021. It ranked third in the list of most-visited art museums in the world.
