Top 8 Best Wholesale Glass Supplier in China / US

Glass cup made of glass, usually made of raw material borosilicate glass, is fired at a high temperature of more than 600 degrees. It is a new type of environmentally friendly tea cup, which is more and more popular.

What is a glass cup made out of?

1. Ingredients, according to the designed bill of materials, weigh the various raw materials and mix them evenly in a blender. The main raw materials of glass are: quartz sand, limestone, feldspar, soda ash, boric acid and the like.

2. Melt, the prepared raw materials are heated at a high temperature to form a uniform bubble-free glass liquid. This is a very complicated physical and chemical reaction process. The melting of the glass takes place in the furnace. There are two main types of melting furnaces: one is a kiln, and the glass is contained in the crucible and heated outside the crucible. The small kiln only puts one cockroach, and the big one can have up to 20 cockroaches. The kiln is produced in a gap-type manner, and now only optical glass and color glass are produced in the kiln. The other is a pool kiln in which the frit is melted and the open flame is heated on the upper side of the glass. The melting temperature of glass is mostly between 1300 and 1600 ゚C. Most of them are heated by flames, and a small amount is heated by electric current, which is called electric melting furnace. Now, the pool kiln is continuously produced. The small pool kiln can be several meters, and the large one can be as large as 400 meters.

3. Forming is the conversion of a molten glass liquid into a solid product having a fixed shape. Forming must be carried out within a certain temperature range. This is a cooling process in which the glass first changes from a viscous liquid state to a plastic state and then to a brittle solid state. The forming method can be divided into two major categories: manual forming and mechanical forming.

4. Annealing, the glass undergoes intense temperature changes and shape changes during the forming process, which leaves thermal stress in the glass. This thermal stress reduces the strength and thermal stability of the glass article. If it is directly cooled, it is likely to break itself during storage or transportation during the cooling process or later (commonly known as cold explosion of glass). In order to eliminate the cold explosion phenomenon, the glass article must be annealed after forming. Annealing is to heat or slowly cool for a period of time to eliminate or reduce the thermal stress in the glass to an allowable value.

Which glass is best for drinking water?

The material of the glass is mainly silica, the ordinary glass is calcium silicon glass, and the better one is high borosilicate, which is called hard glass.

Ordinary wide-mouth glass is calcium-silica glass. Here, we must remind us that the lead content we usually worry about is here. Because calcium-silicate glass is cheap, the production cost is low, and the lead content is not effectively controlled a bit.

Some of the more advanced glasses are high borosilicate. The high borosilicate is almost free of lead, and the process is particularly complicated. It is the best drinking glass.

Which is the best wholesale glass website？

There are many websites for wholesale glasses in China and the United States. We will introduce you to the 8 most popular glass wholesale websites. You can find the best website you think.

8 most popular glass wholesale websites

1. Amazon

You must have heard of this website, which is the largest online company in the United States. It was founded in Seattle, Washington, in 1995. It was one of the first companies to conduct e-commerce on the Internet. He's Amazon. Amazon can offer you a variety of glass types. Their main glasses are lidded glasses that can be drunk with wine or water or tea or milk. This kind of glass is beautiful in price and durable in operation. They usually accept oem and ODM payments. In addition, they are customizable.

2. Baccarat

Baccarat is the world famous brand of engraved crystal/bone china. Compared with lead-free crystals, they are more transparent, more luxurious and more chic. However, some of the crystals made by the brand of porcelain make up the feeling of power. In terms of payment methods, they support t/t and bank card payments.

3. Superleggero

They are the entry-level models in the handmade cups, and the most cost-effective series in the hand-made cups. Every time I see a superleggero, I will be awe-inspiring. Also consider Zalto's entire department and Spiegelau's Athena, both of which are mouth-blown's masterpieces, not always staring at the red feet and black feet. In addition, the 璀璨 and 璀璨 prisms are not handmade (although they are in the manual series). The two series of stems and bases are hand-made, and the bowl is machine-made. But the origin is still Austria (R's mechanism cups are all made in Germany)

4. Riedel

Riedel's feel is very good, it is the kind of texture, the single burgundy is close to half a catty, Bordeaux 180 grams, the hand grip is very good and very practical. Compare Zalto's Burgundy to 100 grams. If it is a girl, it is not recommended to buy. Can't take it.

5.Sommeliers

The basic model can be traced back to the 1950s, such as 4100/16, the Burgundy special field, which was released in 1958. Lido's cups all like to be named after the wine region. So when the black tie was launched in 2008, Riedel defined the Black Tie series as the sommelier's 50th anniversary. "To celebrate the 50th anniversary of the iconic sommeliers Burgundy Grand Cru glass" is no problem in terms of time.

6Heart To Heart

They have a total of 5 glasses, each of which is a double-cup gift box, perfect for gift giving and expressing love. Packing the heart, the name to draw color. The official positioning of the mid-range is lower, slightly lower than the title. The actual location is "wedding gift". It is not recommended for personal use, and the three-section connection is very awkward. Although the prism is also a mechanism cup, it is at least integrated.

7.Ouverture

This series is not a cup type, it is a "nonvarietal specific collection" 12-box box set. Amazon's overseas purchase price is 560 tax-included. For super-class brands, this is already a very low price. When I can drop it to less than 500, I bought a set of self-use tax 460, and I didn't feel bad when I broke it. Dry red / dry white / champagne every 4, the quality and heart are basically the same. If you don't consider the brand, I would recommend Spiegelau's fashion at this price. The price is not bad and the quality is higher.

8.En.china.cn

This website is my love. It was founded in 2003 and is the only state-funded website. The site is very responsive. You can use online chat to contact your supplier and enquire on en-china.cn. Whenever you contact the supplier, he will respond to you within 24 hours. The speed is very reliable.

The sparkle of their glasses lies in "sexuality", which is to make you use it very casually, not so much restrained. With the capacity of O, the cup is directly held, and the distance from the wine surface is still far away, which will not affect the temperature of the wine. It was a little bit of a pleasant sound when I hit the cup. Drink yourself at home, go out and put it in the bag, don't want to use it when you are serious. Although there is no leg, the whole cup is a tumbler design, and you can correct it yourself.

He also offers a variety of payment methods, such as L / C, T / T, Western Union and so on. Of course, you can also negotiate with the vendor to support the payment method. In transportation, en-china.cn usually uses goods that you ship by sea or by air. Transportation takes a long time. But transportation costs are still relatively cheap.

The above is the introduction of some good glass suppliers, choose the right glass for you to act, and finally we end by sharing a secret to distinguish between manual cups and mechanism cups.

Differentiate between manual cups and mechanism cups, a simple way to look at the base. All the mechanism cups, Riedel's logo is a side of the work, the font is angular. The handmade cup is a hand-written flower. Since it is a handmade cup, it is inevitable. Riedel will have, Schott and Lucaris will also have nothing to do with the price. I have seen zwiesel 1872 with a cup bottom, I used a poetry cup with a spiral in the cup, and I also bought Lucas, which is visible to the naked eye. The bottom of the cup (with or without bubbles), the mouth of the cup (with or without curling), the base (flatness), these three places can best see the work of a cup.
