Answer 2

The purpose of the blow pipe used by goldsmith, is as follows -

• The goldsmiths make gold jewellery by melting and reshaping the raw gold metal.
• Now, to melt the gold the goldsmiths use fire and blowpipe.
• The yellow or the outermost region of the flame is considered as the hottest part of a flame and can deliver the maximum amount of heat energy for the melting process..
• Now, by channeling air through the blowpipe, the outermost yellow flame can be directed towards the metal for faster melting process with less amount of fuel burning.
