Step 3: Melting the Gold
Place the cleaned gold scraps into the crucible. Use the tongs to handle the crucible, preventing direct contact with the heat. Position the crucible within the furnace or under the blowtorch flame and gradually increase the temperature.
Step 4: Flux Addition
Add a flux material to the molten gold. A flux is a substance that facilitates the removal of impurities by forming a slag. Common flux materials include borax or sodium carbonate. Stir the molten gold with a rod to ensure proper mixing.

Step 5: Removing Impurities
As the gold reaches its melting point, impurities will rise to the surface in the form of slag. Skim off the slag with the help of a tool like a skimmer or a spoon. This step is crucial for achieving a purer gold.
Step 6: Cooling and Solidification
Allow the refined gold to cool gradually within the crucible. Once solidified, carefully remove the gold from the crucible using the tongs. Clean the gold again to remove any residual flux.
