ANSWER:
Due to combustion property the Goldsmith uses the 'outer zone' of the 'flame' for melting silver and gold.
EXPLANATION:
Because the outermost layer undergoes the 'complete combustion' and is the hottest of the flame. Gold smith is trained in many ways which includes the sawing, cutting, forging, melting, casting, beating, embossing, filling, enamelling and polishing of precious metals.
Combustion is the chemical process where in metals reacts with 'oxygen' and produces the energy during the process in heat and light or both form.
