The Historical Origins of Glass

Detail

Glass, known as flowing glass or glazed glass by ancient people, is actually a colored semi transparent mineral. Tea sets made of this material can give people a sense of bright color and radiance. Although China's glass making technology started early, it was not until the Tang Dynasty that with the increasing cultural exchange between China and foreign countries and the continuous introduction of Western glassware, China began to fire glass tea sets. The plain faced round footed light yellow glazed tea cups and plain faced light yellow glazed tea trays, enshrined by Emperor Xizong of Tang Dynasty, unearthed from the underground palace of Fufengmen Temple in Shaanxi Province, are authentic Chinese glazed tea sets. Although they have primitive shapes, simple decorations, mixed textures, and low transparency, they indicate that Chinese glazed tea sets had already begun in the Tang Dynasty and were considered precious at that time. During the Tang Dynasty, Yuan Zhen wrote a poem praising glass, saying that it was "colored like cold ice, with nothing separated by fine dust. Like a feast that cannot be seen, it can be compared to a jade figure.". No wonder during the Tang Dynasty, when worshipping the relics of the Buddha bones in the Famen Temple Pagoda, glass tea sets were also included in the offerings. During the Song Dynasty, China's unique high lead glazed utensils were successively introduced.


During the Yuan and Ming dynasties, large-scale glass workshops emerged in Shandong, Xinjiang, and other places. During the Kangxi reign of the Qing Dynasty, a palace glass factory was also established in Beijing. However, from the Song Dynasty to the Qing Dynasty, although glass components were produced and were of high value, most of them focused on producing glass art pieces, with only a small amount of tea set products. The production of glass tea sets did not form a scale, and brewing tea was an art form. Tea sets were also quite exquisite. A cup or pot of fresh and fragrant tea, paired with elegant and exquisite tea utensils, can enhance the taste of drinking tea. The tea set family can be described as having a wide variety and a dazzling array. What is the best tea set to choose? Overall, ceramic tea sets are the best, followed by glass tea sets, poor enamel, and plastic insulated cups are the worst.

Factors affecting the formation of wine glass bottles

Detail

We all know that wine glass bottles have high requirements for production. A slight defect will affect the quality and beauty, thus affecting sales. So wine glass bottle manufacturers will consider many factors when producing wine bottles, such as what factors cause or damage the uneven finish of the bottle body, propose solutions according to the problems, and can make good products to give back to customers, So what are the adverse factors for the production and molding quality of wine glass bottles? Now let's learn together.

1. when the glass blank falls into the primary mold, it cannot enter the primary mold accurately, and the friction with the mold wall is too large, forming wrinkles. After positive air blowing, the wrinkles spread and enlarge, forming wrinkles on the glass bottle body.

2. the scissors mark of the upper feeder is too large, and the scissors scar appears on the bottle body after the molding of individual glass bottles.

3. the glass bottle has poor initial mold and molding material, insufficient density, too fast oxidation after high temperature, forming fine pits on the surface of the mold, resulting in the surface of the glass bottle is not smooth after molding.

4. the poor quality of glass bottle mold oil will make the mold lubrication insufficient, reduce the dropping speed of lubricating oil, and change the material type too fast. The design of the initial mold is unreasonable, and the mold cavity is large or small. After the material drips into the forming mold, it is blowing up and spreading unevenly, which will cause spots on the glass bottle body.

5. the dropping speed of the machine is uneven, and the improper adjustment of the air nozzle will make the initial mold and molding temperature of the glass bottle inconsistent, which is easy to create cold spots on the glass bottle body, directly affecting the finish.

6. unclean glass slurry or uneven material temperature in the kiln will also cause bubbles, small particles and small hemp billets in the produced glass bottles. If the machine speed is too fast or slow, the glass bottle body will be uneven, and the thickness of the bottle wall will be different, resulting in mottling.

The advantages of glass bottle packaging

Detail

Glass bottle packaging has various advantages, which make it widely used in multiple industries. The following are the main advantages of glass bottle packaging:


1. Environmental friendliness: Glass bottles are mainly made of natural minerals such as quartz sand, limestone, and feldspar. These raw materials have abundant reserves, are renewable, and glass bottles can be recycled and reused, effectively reducing environmental pollution.

2. Safety: Glass is a material with high chemical stability that will not corrode or dissolve in water and other solvents. This allows glass bottles to maintain the purity and original flavor of their contents without introducing harmful substances, making them commonly used in packaging for industries such as food and medicine.

3. Good barrier properties: Glass bottles can effectively prevent the penetration of oxygen and other gases, maintaining the quality and freshness of the contents. This barrier is particularly suitable for products that require long-term storage or are sensitive to oxygen.

4. Aesthetics: The glass bottle has a smooth surface, good transparency, and can clearly display the color, texture, and purity of the contents. In addition, glass bottles have diverse shapes and designs, are easy to customize, can attract consumer attention, and enhance product image.

5. Reusable: Glass bottles have high durability, are not easily damaged, and can be used multiple times. This not only reduces production costs, but also conforms to environmental protection concepts.

6. Easy to clean and disinfect: The surface of the glass bottle is smooth, and it is not easy to attach dirt and bacteria, making it easy to clean and disinfect. This gives glass bottles a clear advantage in industries with high hygiene requirements such as food and medicine.
