Insert the gold scraps and the flux into the crucible.
Put the crucible into the fire.
Stoke the fire until the heat reaches 1947.52 degrees Fahrenheit, which is the melting point of gold.
Remove the crucible from the fire when all of the gold is molten.
Pour the molten gold into the mold and let it cool.

How is gold purified with fire
Doré must choose the refinery in the trial by fire. In an exciting digestion called refining, it is liquefied in a furnace and then mixed with large amounts of soda ash and regular borax. This effectively separates gold rings from impurities and other metal plates.
How do you remove gold impurities
Acid method – aqua regia method
The key to removing impurities is to separate them from the gold or silver. Royal vodka is a mixture of nitric and hydrochloric acids. This mixture is more intense than strong – plus individual acids.
How do I purify gold at home
Pour 30 milliliters of nitric acid into the container for every ounce of gold. Now let the acid react with all the gold for 30 minutes. Add 20 milliliters of hydrochloric acid or hydrochloric acid for every ounce of gold when using a container. Leave the solution overnight until most of the acid fumes have evaporated.
What method is used to purify gold
The Miller process is simple and fast, but this concept only produces gold of 99.5% purity. Wohlwill’s purity is increased to approximately 99.99 zero percent by electrolysis. In this process, a good cast of impure gold is dipped through an electrolyte solution of hydrochloric acid and gold chloride.

What does the Bible say about gold that is tested in fire
Job 23:10 10 But He knows where I will go; As soon as he checks me, I’ll leave like clockwork. Isaiah 48:10 10 Behold, I have not melted you like silver; I put you in the oven like sorrow. Psalm 66:10 Tenth, O God, you have tested us; The buyers cleaned us like silver. Proverbs 17:3 3 A furnace for silver and a conditioner for gold, but the Lord tests the heart. Revelation 3:18 18 I advise you to buy from Me gold that burns with fire, that you may be rich; and wear bright clothes to hide your shameful nakedness; then apply eye ointment, then you can see. 1 Corinthians 3:12-15 12 If anyone builds on it with plain gold, ancient silver, precious stones, wood, hay, or chaff, 13 his work will pay for what he will be when his day shines. it will be indicated there, and the fire will check the quality of everyone’s work. 14 If the owner survives, the builder will receive a reward. 15 If it burns down, the builders will take damage, but will still be saved if only they run to safety through the flames.
How does fire effect gold
Gold the Coast Titans faced an investigation by the NRL into possible payment of family expenses, which was completed in state court in the David Fifita invasion case in December. Fifita was initially arrested for trespassing on the Gold Coast, but was eventually released by the Queensland Police without charge.
Would it be possible to purify bacterial mRNA by using traditional oligo -( dT )- based technique which is used to purify eukaryotic mRNA
Rapid purification of bacterial mRNA is now possible. For decades, mRNA has been isolated from eukaryotic sources using oligo(dT) selection. However, bacteria lack the slightly stable poly(A) tails found in eukaryotes on the pillars. Thus, it was almost impossible to isolate mRNA from microorganisms – well, now.
