Silver

Silver is the metallic element with the atomic number 47. Its symbol is Ag, from the Latin argentum, from a PIE root reconstructed as *h₂erǵ-, "grey" or "shining". A soft, white, lustrous transition metal, it possesses the highest electrical conductivity, thermal conductivity, and reflectivity of any metal. The metal occurs naturally in its pure, free form (native silver), as an alloy with gold and other metals, and in minerals such as argentite and chlorargyrite. Most silver is produced as a byproduct of copper, gold, lead, and zinc refining.

Silver has long been valued as a precious metal. More abundant than gold, silver metal has functioned in many premodern monetary systems as coinable specie, sometimes even alongside gold. Its purity is typically measured on a per-mille basis; a 94%-pure alloy is described as "0.940 fine". In addition, silver has numerous applications beyond currency, such as in solar panels, water filtration, jewelry and ornaments, high-value tableware and utensils (hence the term silverware), and also as an investment in the forms of coins and bullion. Silver is used industrially in electrical contacts and conductors, in specialized mirrors, window coatings and in catalysis of chemical reactions. Its compounds are used in photographic film and X-rays. Dilute silver nitrate solutions and other silver compounds are used as disinfectants and microbiocides (oligodynamic effect), added to bandages and wound-dressings, catheters and other medical instruments.

Gold

Gold is a chemical element with symbol Au (from Latin: aurum) and atomic number 79. In its purest form, it is a bright, slightly reddish yellow, dense, soft, malleable and ductile metal. Chemically, gold is a transition metal and a group 11 element. It is one of the least reactive chemical elements, and is solid under standard conditions. The metal therefore occurs often in free elemental (native) form, as nuggets or grains, in rocks, in veins and in alluvial deposits. It occurs in a solid solution series with the native element silver (as electrum) and also naturally alloyed with copper and palladium. Less commonly, it occurs in minerals as gold compounds, often with tellurium (gold tellurides).

Gold's atomic number of 79 makes it one of the higher atomic number elements that occur naturally in the universe. It is thought to have been produced in supernova nucleosynthesis from the collision of two neutron stars and to have been present in the dust from which the Solar System formed. Because the Earth was molten when it was just formed, almost all of the gold present in the early Earth probably sank into the planetary core. Therefore, most of the gold that is present today in the Earth's crust and mantle is thought to have been delivered to Earth later, by asteroid impacts during the late heavy bombardment, about 4 billion years ago.

Gold Market

The Gold Market (Arabic: سوق الذهب‎ Souk ad-Dahab; also known as the Qissariya Market, Arabic: سوق القيسارية‎ Souk al-Qissariya) is a narrow covered passageway located in the old quarter of Gaza; it is both a center for trading and buying gold, and location for foreign exchange. The Market lies along the southern edge of the Great Mosque of Gaza, beside the main Omar Mukhtar Street. The Market is configured with a pointed and vaulted roof above the central road, which is lined on both sides by small shops that are themselves roofed by the cross vaults of the covered central road.

History

Gazan judge Sheikh Shams ad-Din al-Himsi ordered the construction of the Gold Market in 1476 CE, under Mamluk rule in Palestine. The Market originally formed a part of a much larger covered market, but most of the area was destroyed by the British Army during World War I.

Throughout most of the 20th and 21st centuries, the market was visited mostly by men and women engaged to be married, to pick out gold jewellery, and by mothers-in-law to purchase gifts for their daughters-in-law. However, because of food shortages arising in Gaza from the Israeli blockade of the Gaza Strip, the Gold Market presently is used chiefly by elderly Gazans selling family heirlooms to raise cash.
