try not to sweat! this is actually the melting point of gold

The association of humans with gold has a very long history. It is believed that more than 80% of the gold that we are using today, has been used for hundreds of years. So gold can be melted and reused in different forms.

In its pure form (24-karat), the melting point of gold in Fahrenheit is 1947.52°. In Celsius, it is 1064.18°, which will be around 1337.33 K (Kelvin). It is that temperature, wherein the metal gold turns from the solid state to liquid state. Gold is one of the few metals that retains its natural color even in the molten form. However, the melting point may vary with the type of metal added to it. In case of gold alloys, where metals like sliver, nickel, copper and platinum are added, the melting point differs from pure gold. These metals are added to gold, so as to change the melting point, to make it harder and also to alter its color

So it is evident that the melting point of gold varies with the different variants. It is said that melting gold to a temperature that is slightly higher than the standard melting point, is beneficial for better flow of the molten metal. However, overheating must be avoided and so the maximum limit should be the standard melting point plus an additional 100 degrees. Even the crucible that is meant for melting gold, must be chosen carefully. Those which are made of graphite can be used only for yellow gold and not for white gold. The crucible must be very clean and any residue in it will contaminate the gold. Different types of torches like butane torch, propane torch, etc. are used for melting this metal. Another requirement is flux, which is a material that is added while melting metals. The flux (like borax) attach itself to impurities, so that they can be easily removed. Once melted, the molten gold is poured into molds, for cooling. If you know the correct procedure, gold can be melted at home, provided you wear proper safety equipment

It is not advisable to melt and mold gold jewelry for reuse, without proper refining. This is because gold jewelry is not pure gold and once you melt it, the resultant metal will be porous and brittle with a pitted surface. Once molded into a new form, it cannot be used on a regular basis, as this gold can break or bend easily. Even a jeweler would cut the cost of refining and remodeling from the value of old gold jewelry, if you approach him for the same.

This metal has been associated with God, wealth and power since time immemorial. Even though, there is no clear-cut evidence regarding the discovery of this yellow metal, it is suggested that it was first used by the civilizations in the Middle-East. However, from that time, till date, the value of this metal has never come down. Even today, it is an important part of global economy

Gold is one of the most versatile and useful minerals known to man. From sconces and sculptures inside the palaces of kings to the wedding rings and family heirlooms of the average Joe, gold has seen more everyday use as new smithing techniques have been born

Far from being an exclusive material for the rich and famous, today, you can find gold in airplane control systems, computers, and smartphones. Do-it-yourself goldsmithing has also become a niche hobby worldwide—not that it has ever fallen out of favor in the past thousand years. So, people looking into the hobby and anyone who wants to invest in gold are curious: What is the melting point of this exceptional metal?

For a straight answer, the melting point of gold is 1,948 degrees Fahrenheit or 1,064 degrees Celsius. That’s hot enough to burn through car engines, the Earth’s crust, and many other metals. But how do you achieve the melting point of gold if you’re looking to make a brand-new ring, bar, or coin?

Before going through the arduous task of building a furnace of your own, you need to know the definitions of some technical terms you might encounter when researching how to melt gold. The five most common ones you’ll find on the internet are smithing, forging, karats, oxidation, and ductility

Smithing and forging are synonyms that both mean using heat to fashion a weapon, accessory, or medium of currency from a metal. A goldsmith is a person who makes gold products exclusively, while a blacksmith is a general term for someone who also works with iron, brass, and other assorted ores. A forge is a facility where smiths work on their projects in the same way a mechanic works in a garage

Karats refer to the purity of a gold item. A 24-karat gold product means it contains gold and nothing else. Pure gold accessories are impractical to wear because they bend easily, which is why you’ll find 10-karat, 14-karat, and 18-karat gold rings but seldom any 24-karat variants

Oxidation is the rate at which gold tarnishes, which is how quickly it will turn black after constant use or a long time in storage. 24-karat gold never loses its shine, but most gold items include copper and alloys, which will absorb oxygen particles after some time and then turn black. You can clean your gold items that have seen oxidation with a baking soda and salt solution easily made at home

Finally, ductility means how far you can stretch gold without it breaking. This quality of gold is one of its most important selling points as people can make leaves, sheets, and microchip parts that are extremely thin, light, and highly conductive. Its unparalleled ductility even makes it a popular addition to luxury desserts like ice creams and cakes in places like Abu Dhabi and New York

The furnace is the heart of every forge. Without it, you won’t a high-enough source of heat to melt your gold and shape it into something useful. Thankfully, you won’t need thousands of dollars of equipment to make a furnace that will burn hot enough for you to begin smithing

First, determine how much gold you intend to melt. The size of the furnace will depend on the demands of the job. If you’re making a sconce or a picture frame, you’re going to need a larger furnace than when you’re making a knife or a couple of chalices

Once you’ve found a cylinder of the right size, create a little hole along its side so you can insert a metal pipe. Your furnace will need a lot of charcoal, so solder a mesh grate about hallway through your furnace. Now dig around your can and create a hole that’s twice as big, and finally place clay and firebrick to intensify the heat

Most gold items you’ll find in the market are zinc, copper, and nickel alloys because these minerals allow gold to keep its shape. Thankfully, none of them bond with oxygen at the same temperature as your precious metal. Using a mixture of sulfuric acid, sodium nitrate, and silica, you can watch the zinc, lead, copper, and nickel parts surface at the top and the sides of your boiling gold, making it easy for you to slough them off

Once you’ve cut the fat from your gold, be ready to pour what remains into a casting dish. Despite its medieval name, a casting dish has nothing to do with spells or witchcraft, but merely a cast iron dish you can use to create bars, coins, and symbols if you’re not going to create a unique design with the delft casting method

Place your gold ore into the crucible and start heating the furnace by setting alight the charcoal surrounding it. As the charcoal turns orange, put your crucible directly on top and add some more until it’s full up to the sides. Turn your hairdryer on so your coals burn with more steady heat

You’re going to need a lot of air and charcoal to reach your nearly 2000-degree Fahrenheit target, so if you’ve been putting in more coal, but the temperature isn’t rising, turn your hairdryer up to a higher setting. However, be careful to stop once you’ve gotten to the boiling point as overly high temperatures might cause your gold to bubble and liquefy to the consistency of cream, damaging its natural form or cause your crucible to explode

Once your gold begins to cool, or even if it’s just a couple of hundred degrees under its boiling point, it will become too dense to pour. You can use sodium tetraborate or borax as a liquid thinner, which will bring up the hardened silica to your gold’s outer surface as it cools

Before your gold begins to cool, take it out of the furnace and pour it into your casting dish. A casting dish with no bends or creases will give you a flat plate or coin shape, perfect for inscription if you want to make it truly yours. If you’d like to turn your gold into another more complex shape, you’ll need to look into gold casting, which is another art form in itself

Since time immemorial, people have been melting gold and turning it into spearheads, sundials, and false teeth. Gold has highly conductive properties, and many stereo manufacturers use it for wires, speaker components, and even phonograph records. The famous phonograph aboard the Voyager I, which communicates what it means to be human to whatever extraterrestrial lifeform it comes across, was made of solid gold

Even though you can deform pure gold with an instrument as simple as a ball-peen hammer, it will become nearly indestructible when you alloy it with copper or zinc. The only way you can shape it and combine it with other metals is to melt it. It’s also the only way to create inscriptions on it, which is a requirement if you plan to sell your gold in the future

The lower the karat rating of a gold item, the less gold it contains. The more metals that dilute it, the more it will change properties. Thankfully, gold’s melting point doesn’t change no matter how many other metals you throw in the mix

However, gold’s color, ductility, and hardness will vary depending on its alloy. Zinc and copper are much less ductile than gold, so if you’re planning to make gold leaves or other sheet-like ornaments, you’re better off with a 24-karat rock

Gold has been valuable even before humans thought up the concept of an economy. Get yourself a hedge against inflation and diversify your portfolio by investing in precious metals today. Call us at 833-600-4653 to learn more about melting gold and making money from it
