if you keep the copper in the outermost layer of the flame of the candle for 30 seconds then the copper will become red hot.

Oxyhydrated flame can be used because it produces a high temperature of 2500?c . It occurs when oxygen reacts with hydrogen. By doing so the time is reduced because such high temperature heats up the copper wire very quickly and we do not need to do hard work in this. So apply this and test this.
