A piece of natural gold was melted in a clay pot in a blast furnace and then poured into the pottery mold. "It's so beautiful."
In the mint workshop, the owner of the workshop, Bai Ya, looked at the gold that was still liquid in the pottery model and let out a sound of admiration. The melting point of gold is lower than the melting point of copper.
Therefore, people in the mint workshop can easily melt it and pour the gold water into the pottery mold.
Jiang Xuan also stood aside. This was the first time the Teng tribe had made gold sword coins, and he wanted to witness the process with his own eyes.
As the gold gradually cools, the surface solidifies and reflects a very charming golden light.
When the gold sword coins were completely cooled, Bai Ya picked up a bronze hammer and gently smashed the Tao Fan into pieces. The gold sword coins inside were completely exposed.
Bai Ya picked up the gold knife coin, looked through it, found that there was nothing wrong with it, and then presented it directly to Jiang Xuan.
"Chief, see if this works."
Jiang Xuan took the newly minted gold sword coin. It was much heavier than the bronze sword coin, and it felt more delicate and beautiful.
However, bronze knife coins can be used as knives with a little polishing, but gold knife coins cannot be used as knives.
Because it is too soft, it cannot cut anything slightly harder and the blade will curl.
It can be said that, apart from being used as handicrafts for ornamental decoration, gold knife coins do not have much practical value.
However, it is an important part of the new currency system Jiang Xuan plans to build.
Gold, because of its rarity, wear resistance and corrosion resistance, is naturally suitable for making currency. However, currencies such as gold knife coins have been separated from the original practicality of knife coins.
If it can be accepted by various tribes near the Vine Tribe, it means that the currency and credit system of the Vine Tribe has been initially established.
Bronze knife coins and gemstone knife coins, because of their practical value, are actually still a kind of goods, but they are just a kind of goods that are highly accepted by various tribes.
As for gold, because the tribesmen have basically never been exposed to it before, and they don’t know how to use it, if it can be accepted by various tribes, it must be because of the credibility of the Vine tribe.
Only if everyone believes that gold can be exchanged for the required goods if the gold is taken to the Teng tribe, this kind of currency can be circulated.
The transition from a highly practical currency to a currency backed by tribal credit is an extremely important transition.
Once the gold knife coins are circulated, it means that various tribes will truly change their barter trading habits. As the leader, the Vine Tribe will also gain huge benefits from the future currency system!
Jiang Xuan looked at the gold knife coin repeatedly and said to Bai Ya: "It feels a bit rough, and I need to polish it again to make it smoother and shiny."
White Fang nodded and said, "I'll polish it right away."
White Teeth took the gold knife coin, heated it on a shorter stove, then picked it out with pliers, placed it on a bronze chopping board, and struck it with a hammer.
This processing technique was discovered bit by bit during the casting process of copperware. Of course, Jiang Xuan gave them a few words of advice based on his previous life experience, which saved them a lot of detours.
Bronze wares include not only bronze, but also pure copper and other copper alloys according to the needs of the wares.
For example, copper pots are cast from pure copper. After casting, they are often rough and need to be heated and polished multiple times to achieve the best results.
"Ding ding ding..."
As White Teeth continued to heat and tap, the rough parts of the gold coin were gradually flattened and smoothed, and the overall lines became smoother.
When he finished hammering, many fine hammer marks appeared on the gold coins. These hammer marks made the gold coins look stronger and the reflected golden light more dazzling!
But, how to polish it?
Bai Ya's method was still the same as sharpening bronze swords and coins, directly looking for a whetstone. However, Jiang Xuan stopped him and gave him a suggestion.
"Try it with gem knife coins."
Jiang Xuan clearly remembered that in a documentary he watched in his previous life, after the gold was struck, it was polished with an agate knife.
There are many high-quality stones in the mint workshop, which are used to make gemstone coins.
Jiang Xuan chose a gemstone knife without an edge, similar to that of agate, and asked White Teeth to polish it.
White Fang looked at the not-sharp gem knife and coin, his eyes a little confused.
Can this thing really polish gold knives and coins smoother? He has some doubts about this.
However, since it was the leader who said it, he only needs to do it. There is no need to question it and he does not dare to question it.
White Fang then took the unedged gemstone coin and diligently scraped the surface of the gold coin.
As the gem coins and gold coins continued to rub against each other, a magical scene appeared.
There is basically no change in the gem sword coins, but the surface of the gold sword coins has become brighter and brighter. The golden color makes people unable to take their eyes away from it.
The leader is so powerful! At this moment, Bai Ya's admiration for Jiang Xuan increased again.
Who would have thought that with extremely hard gemstone coins, gold coins could be polished so smooth and bright.
"Chief, it's polished."
When Bai Ya handed the polished and dazzling golden knife coin to Jiang Xuan, he was in a very excited state and his hands were trembling slightly.
Jiang Xuan took the gold sword coin. The rough feeling before was gone, replaced by a smooth touch, and the whole coin was shining with gold.
Facts have proved that high-quality stones like agate can really polish gold. Perhaps not only gold, but also softer metals such as copper and silver can be polished.
In fact, this method of polishing with gemstones does not polish the gold, but flattens it.
The reason is that gold has excellent ductility. As long as you keep scraping it with something smooth and hard, the uneven parts of its surface will slowly expand and eventually become flat and smooth.

White Fang asked in a low voice: "Chief, do you want the gold knife coins to be put into the trading area?"
Jiang Xuan thought for a while and said: "Don't invest in the trading area for the time being. We must first let people from various tribes know gold and like gold."
"After they all like gold, we will introduce gold knife coins, and they will be more receptive."
White Fang asked again: "Then how can we make people from other tribes like gold?"
Jiang Xuan smiled and said: "Then it depends on the abilities of our Vine tribe members. From today on, some people will be dedicated to studying gold inlay technology."
"From now on, we will inlay all kinds of precious ornaments, precious utensils, and precious weapons with gold."
"We need to connect the two words gold and precious, and let everyone understand that only precious things can be inlaid with gold. Over time, everyone will naturally recognize the value of gold."
Jiang Xuan looked at the shining gold sword coin again and said, "I believe that the big shots from each tribe will like such a beautiful thing."
After hearing Jiang Xuan's words, the admiration in Bai Ya's eyes became even more fanatical.
In his heart, Jiang Xuan is like an omniscient and omnipotent god.
Soon, Jiang Xuan transferred six skilled people from the three workshops: pottery workshop, stoneware workshop, and smelting workshop, and assigned them a separate room near the mint workshop to specialize in gold inlay technology. p>
They fully understood the properties of gold and found ways to inlay gold on various materials.
Jiang Xuan believes that it won’t be long before various precious items inlaid with gold will appear in the Vine Tribe’s trading area, and these items will become unique marks for the Vine Tribe’s goods.
The mint workshop also continues to make gold sword coins, but the quantity of these sword coins will not be large, and they will not be put into the trading area for the time being, but will be stored for future use.
