What type of cups do you use to drink water in your life? Have you used quality and inexpensive double glass cups? If you use it, then you know what glass material is used to make the cup, is it good or bad? Today Yongkang Yatai cup industry to tell you how to identify.
A, how to distinguish between crystal glass and ordinary glass
Crystal glass, also known as lead crystal glass, according to the level of PBO (lead oxide) content is divided into high (24% PBO and above), medium (18% PBO), low (12%-16% PBO) three grades. The grade classification standard is somewhat similar to gold. Therefore, many merchants will also be high-grade crystal glass jokingly called "24K". If you go to buy more similar "jargon", the other party will also feel that you are more insiders, encounter individual unscrupulous business, but also dare not easily fool you.
Crystal glass according to the level and division, there will be three obvious differences: 1.
1, sound: gently knocking or finger bouncing. Crystal glass can emit a crisp metallic sound, and swirl in the air with a beautiful aftertone. We will see in the movie there will be in the reception, high-class banquet clinking glasses of footage, wine glasses collide with each other to make that crisp sound is. The sound of crystal glass is also different for high and low grade. Like some low-end crystal glass or ordinary glass sound is more muffled.
2, feel: the same volume of crystal glass and ordinary glass is not the same weight. High crystal glass will make you feel calm and heavy hand. Similarly, the lower the grade of crystal glass, the lighter it will be. Ordinary glass weight is more self-evident.
3, luster: a high-grade crystal glass apparatus to the light rotation, you will find that it is like a fine craft. White, crystal clear and refracted a charming colorful light, while low-end crystal or ordinary glassware in the above aspects will have a relatively large gap. What's more, in some ordinary glassware is littered with a large number of bubbles inside, the color will also look dirty, dark.
B, the purchase of crystal glass
The market is full of crystal glass styles, which is full of a large number of inferior products and fakes. Because of the large cost difference between crystal glass and ordinary glass, so there are many unscrupulous businessmen will be some high white glass as crystal glass sold to consumers to make huge profits. The style and color of these ordinary glass often imitate the design of big brands, but the workmanship is very rough. Please identify them according to the points I mentioned above to protect your own interests. The high-grade crystal glass on the market is divided into several types by region, arranged by grade as follows
1, imported high-grade crystal glass.
2, foreign technology domestic production of high-grade crystal glass.
3, low-end crystal glass and ordinary glass from small factories in the south.
The region of imported crystal glass mainly comes from Italy, Germany and the Czech Republic. The products of these three countries are the world's leading in terms of technical workmanship, design style or historical era. It is also the focus of small glass factories to imitate the object. Of course, the price is also very expensive. Therefore, also as a diplomatic occasion, one of the gifts from the head of state. Representative brands are Bohemia, Czech Republic, etc.
With the drive of the market system, some foreign crystal glass manufacturing companies with a long history choose to set up factories in China for production. The main consideration is the cost and environmental protection two factors. Here you can not scold those foreigners bad, huh. This is the global development trend. As if many developed countries exceed the carbon dioxide emissions, to buy indicators from developing countries. China's annual sale of carbon dioxide emissions is also a considerable amount of it. Foreign technology, foreign production lines to produce top quality crystal, while the price is relatively low. The representative brand of this category is "beauty-eagle", called "beauty-eagle" in English
Seems to be a wholly owned by the Italian enterprise. Its products involved in vases, fruit plates, wine sets, ashtrays and other high-grade crystal crafts. Each product is labeled with 24% PBO (high-grade crystal glass) when it leaves the factory. Because its workmanship is comparable to imported products, while the price is relatively low (it is said that domestic sales have now started to turn to export). Therefore, it is well received by the market. With the passage of time, many small factories also began to imitate their products.
