This introduction: Pan Yansheng, member of the third artificial gem professional committee of the China Treasure Association, director of Shanghai Wanbao Da Crafts and Crafts Factory.
Inly, various types of archeological excavations are known, early humans were worn on the body with various shells, animal teeth, gravel and other necklaces. As early as the Han Dynasty, people used various lapies stone, malachite, and agate as jewelry inlaid on bronze. It can be seen that gemstones have inseparable connections with human life.
With the development of society and the continuous improvement of human living standards, people's demand for gems has also increased, especially in recent decades, gem trade has also developed greatly. However, the huge gem trade volume makes natural gems more precious and less and less. In this case, artificial gemstones have gradually filled some gem trade needs. At present, as a commonly used artificial gem material, there are several categories such as rigid jade gems and synthetic cubic oxidation. Glass is one of the artificial gemstones and is mainly used as imitation gems. This article mainly analyzes the use and development of "imitation gem glass" in artificial gem materials.
First of all, let's take a look at the application of glass as artificial gem materials. When it comes to glass, many people may think of lamp utensils. In fact, people have used glass as a "jewelry accessories" for a long time. Because the production technology was limited at the time, the glass was still very rare, so the value of the glass and other gems were not too much at that time. Large difference. With the development of the glass manufacturing industry, the production of glass is getting bigger and bigger, it gradually loses a major element as a gem scarcity, and it is more used in daily products and utensils.
If glass, as a material application for artificial gemstones, it is generally not enough attention. The key is that it is too ordinary and the hardness is not high. The hardness of the Mo's hardness of the synthetic gemstone is 9, and the hardness of the synthetic cubic oxidation is 8.5, and the cognitive Mo's hardness that people should have in the gem should be above 7, and the hardness of the glass of the glass is 5 ～ 6. From the perspective of the melting point, imitation gem glass has a large advantage. Silicon dioxide must not melt at high temperatures above 1700 ° C, and make melting crystal glass, with high melting costs. The melting point of the common imitation crystal glass (lead glass) on the market is much lower, usually within 1000 ° C, which can be fired in a small capacity of a small capacity. Make it play a great role in future development. Glass is transparent, corrosion -resistant, heat -resistant, strong plasticity, and its electrical and optical characteristics, so that glass can be used as imitation gemstone, and glass is continuously studied by people.
While people are studying natural gems or research on artificial gemstones, the objects of their research are mainly "materials" and "color". Similarly, the study of glass should also be focused on "materials" and "color". In terms of "material", the imitation gem glass we usually use can be special optical glass. The melting temperature of special optical glass is low. If the amount of sodium oxide is increased, the melting temperature can be reduced to the temperature that can be produced by the general kiln. ~ 6). The glass has a strong plasticity. As long as the chemical combination is adjusted appropriately, the purpose of imitation gemstone can be achieved. The "lead glass" we often use is to add lead in the glass. After adding lead, the density of the glass will increase. The slower the transmission of light in the glass, the greater the refractive index; the smaller the density, the smaller the refractive index. In order to increase the refractive index of ordinary glass, the content of lead is generally added between 25%and 50%. Some special glass contains even more than 80%, and the refractive index is high. However, the application of lead glass on the jewelry also has some problems, which will cause "lead poisoning" pollution.此外，“铅”是低熔点金属，而且容易产生氧化，现在有些人在加工饰品时先镶嵌好后再电镀，在电镀的过程中铅就会氧化，使饰品表面发“朦”，犹如“薄Fog "affects the smoothness of the jewelry. Furthermore, lead has pollution, which allows some countries to ban. For example, the EU standard is less than one -thousandth, so some manufacturers have considered removing lead in production. The author believes that through the reorganization of the material of the glass, the glass can reach a better refractive index without lead. In order to meet different needs, optical glass has many brands to choose from.
Let's take a look at the importance of "color" for gem material. The reason why gems are loved by people is of course an indispensable factor, but the main reason for the market and people is widely accepted by the market and people. The material of ruby ​​is "Gang Jade". It is a very ordinary mineral. It can be seen in many places, but only the transparent rigidity of dark red to purple -red can be called ruby. To confirm whether a ruby ​​is valuable, it is "pigeon blood red" or "cherry red". In addition to the same "material", the decisive factor is the color of the gemstone. Similarly, compared with the "material" research of artificial gems, "color" research is more important. The author found that there is a very common phenomenon in gem synthesis. The higher the melting point of the material, the greater the hardness, but the less the color, because many colorants cannot bear such a high temperature (volatilized). For example, the color of Guan Jade Gem is more color than diamonds, and the color of the synthetic cubic oxidation is more color than the corundum gemstone, and the glass is much lower than the melting point relative to the jade gemstone and the synthetic cubic oxidation. Therefore, it is in color in color On the problem of color rendering, the advantages are fully displayed. We can make any color and shades of color. The red, yellow, blue, green, purple, etc. in nature can be fused. Experience tells us that adding "oxidation" to the glass base, it is expressed as a delicate pink glass, like a peach red tourmaline; after adding "oxidation", different colors are appeared in different light. "Trimming glass"; adding "three -chloride gold" to the gold and red glass of elegant "rose red". Many metal oxides and some other substances can make the glass color, such as cobalt, copper, iron, nickel, manganese, and manganese. Chromium and so on. Glass has been applied in the field of artificial gemstones so far, which is inseparable from its colorful colors. It can be said: "In the field of artificial gemstones, there are no more materials and lower prices in the field of artificial gemstones. Therefore, the cost -effectiveness of the glass is self -evident. "
The people think that artificial gem jewelry is about to be supplied to poverty -stricken places. I think it is the opposite. The more poorer places, the more pure gold and sterling silver. The jewelry of 18K gold in those places is not necessarily better than the pure gold jewelry. Because it is not easy to buy or accessories, you need to buy preservation products for children and grandson. In town, people began to set their sights on artificial gem jewelry, because artificial gem jewelry followed the trend, followed the market, followed fashion, and met the needs of modern youths, so the wider walking. There is a very common phenomenon abroad: After buying an artificial gem jewelry, we only wear it a few times, and most of them are worn to half a year. It is completely fashionable decoration. With the improvement of people's living standards, the amount of artificial gem jewelry will increase, which is an indisputable fact. Before the reform and opening up, the country was mainly gold jewelry. At that time, the amount of natural gemstones was very small, let alone artificial gems? Intersection About the mid -1980s, there were rare earth gem glass in the market at that time, which was more popular, but at that time, due to the small market demand and production process equipment, the production volume was not very large. The real impact time in the market was still in the late 1980s. At that time, three types of gem glass products appeared in the market (high refractive index rare earth glass, imitation cat eye glass, imitation Australian jade glass). The jewelry market was really hot for a while. At the beginning, some people were inlaid with these imitation gems on the gold jewelry. Later, as the manufacturer gradually increased, the output increased, and the price decreased, these imitation gem glass gradually switched to the thin gold jewelry (a kind alloy).
In 1994, at the first International Jewelry Exhibition in Shanghai, the author and a friend of Xinjiang and a friend in Yunnan co -leased a booth. On the left is the emerald and gem of Yunnan, and on the right is the tourmaline and sea blue gemstone in Xinjiang. The author specializes in the noodles of the three varieties of cat -eye glass, high refractive index rare earth glass and imitation Australian jade glass. The result is very interesting. The two counters on both sides are deserted, and we imitate the gem glass jewelry counters. The key to the emergence of this situation is that we have beautiful products and low prices, which makes the author see the potential of the color glass imitation gem market.
Is when I went to Wuzhou, Guangxi Wuzhou in 1995, the artificial gemstone on the Wuzhou market was still mainly Jade gem and synthetic cubic oxidation. There are some problems on electroplating. At that time, some people proposed whether to produce high refractive indexes that can be suitable for electroplating. The author went back to study and succeeded. When I went to Wuzhou again in 1996, I brought the 12 -colored color imitation gem glass products of the newly produced. The slogan was "colorful glass that can be plated", which caused a sensation in the market and achieved certain benefits. But at that time, the amount of production was not large, and the application of imitation gemstone color glass was still in its infancy. The time to really use imitation gem glass is from the late 1990s to 2000, which is mainly due to the popularity of alloy or silver jewelry. Many Taiwanese and foreign companies using these imitation gem glass products in Wuzhou are embedded on alloy or silver accessories, and pushed the use of imitation gem glass to a peak. It can be said that in the domestic color glass as a large number of artificial gem materials, it starts from Wuzhou and develops with the development of the Wuzhou gem market.
, but the problems of the glass imitation gem market are also obvious. In just a few years, this product has entered a low -grade competition. This is probably a common problem in the current domestic market. The product is selling well, and that product quickly enters the vicious competition. For the current imitation gemstone color glass on the market, it is better to call it craft glass than calling it imitation gem glass. The imitation gemstone color glass is used as a artificial gem material for accessories. It has certain requirements and boundaries, and has high requirements for its hardness, refractive index, dialysis, texture, and other aspects. To meet the degree of high requirements, first of all, the selection of raw materials is very strict. Secondly, it is not tolerant of the production process. Generally, the second melting of Xiaoyu can be used to meet the requirements. As far as these two points are used, the high cost of the product is also the high cost of the product. certain. And now most manufacturers use kiln crafts to produce imitation gem glass. There is no doubt that the quality must not be compared with the imitation gem glass produced by Xiaoyu. In the vicious circle.
On the problem of "color", the imitation gem glass, as the name suggests, is a glass that imitate the color of natural gemstones, and its color world is limited. What red is pigeon blood red? What kind of blue is "Yarcus Chrysanthemum"? What kind of green is "Colombian emerald" and other knowledge about gemstone colors must be mastered by studying imitation gem glass. But now, the manufacturers of colored glass do not have the energy to study these gems. As long as the red ones are called "ruby", as long as the blue is called "sapphire", the green ones are called "emerald" Essence In order to reduce costs, try to simplify as much as possible in the production process, and use the cheapest chemical raw materials used, so that it is not easy to operate and difficult to stabilize color glass production, which is even worse. The language is unique from a business perspective, but from the technical perspective of products, it is not a good way. This is why the color of the colorful glass of gemstones is getting more and more, but it is becoming more and more unstable. Although the current product products are chaotic, I think that imitation gem glass still has room for survival. Although it is similar to ordinary color glass, they are at different grades after all. Those companies with scientific research capabilities and rich professional knowledge and design capabilities will not work in vain. It can be said that what kind of natural gems are there, what kind of imitation gem glass, a group of imitation gem glass that is different from ordinary color glass will definitely reproduce in the gem market.
