Goldsmiths use the outermost part of the flame to melt gold and silver because it provides a higher temperature while minimizing the risk of contamination. The outer flame is more oxidizing, which helps to keep the metals clean by preventing impurities from being absorbed. Additionally, this part of the flame allows for better control over the melting process, ensuring that the metals reach their melting point efficiently without overheating.
Because it is the hottest zone of a candle flame.

goldsmiths make gold!
Species is a term used as early as the 1600's for gold and silver.
Goldsmiths are experts in making objects out of the metal "Gold", goldsmithing is a trade like silversmith or blacksmith.
Blowing air through a blowpipe helps create a hotter and more concentrated flame, which can help melt gold more efficiently. The outer zone of the flame is typically the hottest part and by directing this heat onto the gold, it can facilitate quicker and more uniform melting. Additionally, the blowpipe allows the goldsmith to have more control over the melting process.
number of electrons capable of freely moving in the outermost shell of an element. eg. Copper
no, Muhammad bin tughlaq's policy wasn't good because he issued copper coins which had the the same value as those of gold and silver without thinking of the consequences of this. he didn't think that that the goldsmiths will start minting copper coins and gold and silver coins will disappear from the market
In a silver-gold alloy, silver is the solvent and gold is the solute. Silver acts as the base in which gold is dissolved.
Gold does not produce a flame color when burned. When heated, gold will melt and form a shiny, metallic liquid.
Metals like aluminum, gold, and silver have relatively high melting points and cannot be boiled with a Bunsen flame, as their melting points are much higher than the temperature a Bunsen flame can reach. Metals like lead and tin have lower melting points and can be boiled with a Bunsen flame.
Gold is heavier than silver. Gold has a higher density than silver, which means that a specific volume of gold will weigh more than the same volume of silver.
