Melting Gold and Its Impact on the Metal’s Properties
Laurence uses a specialized heating device known as his ‘melting furnace’ in order to melt down valuable pieces of gold metal into molten form.
To further elaborate, when Laurence melts gold using an electric furnace with borax flux, he creates conditions that allow the separation and purification process for pure gold from other metals present at a mining site or scrap sources like jewelry containing mixed alloys.
Borax Flux: The primary use of boric acid (borax), in this case as a flux during melting is to lower its boiling point so it can be used effectively by Laurence’s electric furnace, thus facilitating the separation and purification process for gold from other metals present at mining sites or scrap sources.
Melting Gold Piece: When he melts down valuable pieces of gold metal into molten form in his specialized heating device known as an ‘electric melting furnace’, it allows him to melt away impurities like iron or black sand which may be mixed with the original piece, thus making sure that only pure gold remains after cooling and solidifying.
