The first private enterprise authorized to produce artificial gems in the country is located on the southwest side of the city of Elte and is named "Philosopher's Stone".

This name is very ordinary, but the enterprise name registration system is only available in the Phoenix Kingdom. There is no duplicate name yet, so it is considered to be picked up.

The closest market to Elte is five kilometers away, and the road to the bauxite mining area is relatively rugged, about twenty kilometers.

The local bauxite was originally occupied by a group of bandits, but it was scared away many years ago by the suppression of bandits along the railway.

It was used here earlier, and it was developed before Elter was incorporated into the Kingdom.

Bauxite is a very basic magical material locally, which is very cheap to the magicians, but in the eyes of Rainbow Metal, it is a bit expensive as the main raw material for aluminum smelting.

Fortunately, the bauxite mine itself is very hard and of the same level as the coal mine. The mining difficulty is low and the cost is limited. After the entire Fenggu section belongs to the kingdom, under the urging of the Rainbow Group, the mining area carried out a wave of equipment upgrades, which suppressed the bauxite price.

"Philosopher's Stone" is just a ready-made bauxite production chain and is produced using different processes. Many equipment and technicians are seconded from Rainbow Metal.

Rainbow Metal is also a private company and will not do business that will suffer losses. Magic Stone signed an agreement to purchase chemical preparations needed for production in the future from Rainbow Chemical. When the price is lower than the border quotation, the procurement ratio will not be less than 70%.

The main component of bauxite is hydrated alumina. After pulverization, the ore is initially washed and removed solubles, and then chemical preparations are needed to participate in the removal of impurities.

After a series of chemical reactions and mechanical drying, the last thing left is hydrated alumina, which uses the same process as the electrolytic aluminum of rainbow metal.

Hydrates cannot be directly entered into the crystallization furnace. They need to be turned into anhydrous alumina in the low-temperature furnace first, and then seed crystals in the mold, fill with powder, etc. as needed.

The entire process is very mature. In the few months of construction, the Philosopher's Stone has tried many furnaces.

However, they have many ideas and have already started to tinker with new products before they are officially mass-sales.

The new product is also alumina gemstone, the only difference is to add color to it.

The gems that have flowed out of overseas through various scrap channels have been well known to many people.

This gem has a faint blue under bright light, but the light intensity is slightly lower, and it looks colorless and transparent, which is a manifestation of extremely high purity and is very popular among mages.

However, the lack of color has led to less attention from ladies and prodigal children who like to paint. They lack a strong purchasing power, which has kept its price falling.

Now that the Philosopher's Stone is operating by itself, of course, he wants to attract more customers, and the purchasing power of the ladies is very exaggerated.

But its new company does not have its own technical personnel, so how can it be so high-end? It can only ask for help.

The knowledge dissemination atmosphere in the kingdom is good, and companies do not mind teaching any knowledge they cannot use.

When adding colors to the gems, there are several choices for chromium, cobalt, iron, and titanium. They must be added in the form of oxides or salts, not elemental materials. The relevant knowledge of the first two is given by Rainbow Metal, while the latter two are bought from steel mills, and there is also an approval process in the middle.

Chromium is strange. Chromium oxide is green, but this ingredient is ruby ​​when it is involved in alpha alumina crystals.

Cobalt is a typical precious blue. Almost all positive blue mineral pigments and dyes contain cobalt. Adding them to gems will also make the gems look blue.

The colors given by iron and titanium are different, but they can also be added. The principle can be used to refer to gem-grade rutile, which contains more than 98% titanium dioxide and iron-containing rutile will look very similar to rubies and can also be finely adjusted to create gold.

In addition, you can also try adding nickel... In short, if it does not affect the low-temperature crystallization effect, you can try adding one plus if you can think of it. What if it performs well.

The Philosopher's Stone has customized special molds, specially used to experiment with small gemstones of various colors.

Here, because the Philosopher's Stone uses the early low-temperature crystallization technology of about 1800 degrees, large gemstones will have multi-crystal imaging cracks, and only small ones can be made similar to natural gems.

Using a special mold, a stove can make hundreds of small gems, and each ingredients have slight differences. After trying for a while, they really made some good things.

Forget red sapphires, they are too ordinary and have no competitiveness compared to natural gems.

The most amazing ones are made, one star color and one pink gem.

The star color body is a slightly purple low-saturation sapphire, cut into a standard eight-heart eight-arrow, with 57-sided craft body, and each face will appear in four colors: transparent, white, red and blue.

The pink gem highlights a pink one, and the color is more like a transparent gem.

Both are varieties that can definitely blind men and drool women.

"Okay, OK, OK."

As a shareholder of the Philosopher's Stone, the former Lord Elte saw two new types of gemstones, and praised them, but his heart couldn't stand it.

Elte has been building a city for more than two hundred years, but he doesn't even know that the bauxite at his doorstep can be used as gems, and can also make such thrilling gems.

I feel like I lost several hundred million!

gold!

It is produced now, but it cannot be sold at a very high price. It is just used to distinguish it from the main products and sell it as a high-end product.

By the way, ordinary artificial gems produced by Philosopher's Stone are different from those produced by gem workshops in Iron and Steel Factory.

The products there can only appear blue under sunlight, and the indoor lights cannot be seen at all. The basic gems of the Philosopher's Stone will be reddish when there are enough indoor lamps, and this red will become a little lighter under sunlight.

The alchemist invited said it should be the cause of the impurities.

As a magic storage prop, color differences or even cut-section imaging cracks do not affect the use, but this difference also causes the Philosopher's Stone to not be under the banner of some strange and strange signs.

The official recommended retail price for domestically offered is 500 yuan per kilogram.

...If the investment in the construction of a factory is not calculated, it only counts the part of the raw materials to the finished product, and the profit is at least 800%.

However, it actually contains a money that needs to be subsidized for other work, which is not only a corundum abrasive project replicated from the Locomotive General Factory. The situation of the Locomotive General Factory is different. They directly purchase horse-shaped alumina from rainbow metal, without starting from bauxite, and the cost is also relatively high.

Corundum abrasives and artificial gemstones are the same thing, but the crystallization scales vary and the temperature requirements are lower.

Low-temperature artificial gemstones are polycrystalline, but they are actually single crystal combinations of giant scales. Corundum abrasives are truly tiny polycrystalline and are regarded as white irregular-shaped particles.

Reducing the market price of corundum abrasives is the only official requirement in the entire civilized project of artificial gems. On the premise that the entire project is equivalent to free money, there is no way to refuse to agree.

The official guidance of the corundum part is 2,000 yuan per ton, which is twice the crude steel. It is a complete loss of money when it comes to the current scale of the Philosopher's Stone, and only a small profit can be made at an annual output of about 50,000 tons.

The question is how can it reach an annual output of 50,000 tons? Who can use it? Sell it abroad. Whether those people can distinguish between alpha and horse-type is suspense, let alone batch procurement.

The former lord's counselor helped analyze it and believed that the nature of corundum has great advantages over traditional abrasives. It is easy to cultivate the corundum usage habits of domestic enterprises at low prices, making them feel that washing and then using it will be a waste. As the population of the kingdom increases year by year, it is not impossible to consume tens of thousands of tons a year.

In short, at this stage, we need to subsidize this place with low-priced gems.

The export part is limited by transportation capacity, and it is boring to export corundum powder. It is still more reliable to gems, but the official does not seem to have any supporting measures to restrict foreign merchants from purchasing domestically.

Here, 1,000 yuan per kilogram is used to takeout, so others will naturally come to the country to find an agent to come to their homes for purchases, and they will not be able to keep domestic buyers out.
