Glass teaware is generally made by melting and forming a mix of such materials as quartz sand, limestone, and caustic soda at high temperatures and then cooling. There are many kinds of glass teaware such as crystal glass, colorless glass, jade-colored glass, gold star glass and opaque glass teaware.

Various other vessels such as wine glasses, bowls, plates, cups, vats etc. can be made of glass, mostly being colorless but also with colored or enameled glass.

Introduction to Glass Tea Ware
Glass tea ware is a type of teaware made of glass. It has many advantages, such as being able to withstand high temperatures and being able to view the color and clarity of the tea leaves or tea infusion. These qualities make it a popular choice for making and enjoying tea. The glass also helps retain the flavor and aroma of the tea. Glass tea ware often comes in a variety of shapes, sizes, and colors, making it an attractive addition to any home.

Glass, referred to as “liuli” or “liiu” by the ancients, is actually a colored semi-transparent mineral. Tea sets made of this material can give people a bright and shining feeling. Although Chinese liuli technology started early, it was not until the Tang Dynasty that with the increasing exchanges between Chinese and foreign cultures, Western liuli wares were continuously introduced into China, and Chinese started to burn liuli tea sets.

A pair of plain yellow glazed tea cup and saucer unearthed from Fumen Temple in Fufeng, Shaanxi, which were offered by Emperor Xizong of the Tang Dynasty, is an authentic Chinese glazed teaware. Although its shape is primitive, decoration simple and quality rough with low transparency, they still demonstrate that the Chinese glazed teaware had started in the Tang Dynasty and was considered a treasure at that time.

Tang Dynasty’s Yuan Zhen praised the beauty of glass by writing a poem, saying it is “as colourful as ice but without anything to screen its thinness. The tea cups appear invisible at banquets; how much more so in front of a beauty.” No wonder that during the Tang Dynasty, glass tea sets were also included among offerings for the Fo Men Si Tower Buddha Relic. In Song Dynasty, China’s unique high-lead glassware was successively created. During the Yuan and Ming Dynasties, large-scale glass workshops appeared in Shandong and Xinjiang provinces. During Qing Kangxi’s reign there was even an imperial glass factory set up in Beijing. However from Song to Qing although there were glass wares produced they were expensive and mostly used to produce artistic pieces with only a small number being used as tea sets preventing it from forming into a mass production of such items.

Development

With the rise of the glass industry in modern times, glass tea sets quickly became popular, due to its transparent texture, eye-catching luster and great plasticity. Therefore, the various shapes and wide range of uses of glass tea sets, combined with its low price and convenience of purchase, have been highly praised by tea drinkers. Among the many glass tea sets, glass teacups are the most common. When used to brew tea, the color of the tea soup, the shape of the tea leaves and their movement during brewing can all be seen at a glance. Therefore, when used to brew delicate famous teas, it is very suitable for entertaining guests at home and provides an excellent way to drink tea. However, glass teacups are fragile and easily broken. They are also hotter than ceramic ones which is a slight imperfection. The modern glass tableware has made great progress: its texture is transparent, lustrous and has great plasticity with various forms and uses.

Characteristics

1. High Quality
2. Great Price
3. Durable
4. Easy to Use

In modern times, glassware has seen great development. With a transparent texture and glossy shine, glass has great malleability that allow for various shapes and uses.

Brewing tea with glassware, the vibrant color of the tea soup, the tenderness and softness of the tea leaves, the up-and-down movement of the tea leaves during the entire brewing process, and the gradual unfolding of the leaves can be seen without a doubt. It can be said to be a kind of dynamic art appreciation. Especially when brewing various famous teas, glassware is crystal clear with misty vapors in the cups, clear green with buds standing elegantly. Looking at it is delightful and interesting. Moreover, glassware is inexpensive and popular among consumers. The disadvantage of glassware is that it is easy to break, and it is hotter than ceramics. However, there are also tempered glass products that have been specially processed which are not easily broken and are usually used on trains and in catering services.

The disadvantages of glassware are that it is easily breakable and hotter than ceramic.

Performance

This product mainly uses high-quality, environment-friendly borosilicate green glass with an expansion coefficient of 3.3. Its physical and chemical properties meet the German DIN standard and American ASTM-E438 Grade A standard, which is equivalent to Pyrex-7740 glass manufactured by the Corning Company in the United States. In production, this kind of glass is widely used with a series of advanced technologies such as progressive automatic feeding, immersion temperature measurement, furnace bottom bubbling, mechanical stirring, electroassistance dissolution, laser technology and electric control tunnel kiln. It has an instantaneous temperature difference of -20 to 150 degrees Celsius, excellent chemical stability, low expansion coefficient and resistance to high temperature shock are the most remarkable features of this type of glass product. It is comparable to glass products in Europe and America with stable quality and mainly exported to countries such as Japan and Europe.

This borosilicate glass tea set is heat-resistant and can be used with open flame or in a microwave.

Process

The most common forming method in glassware manufacturing can be divided into two categories: manual blowing and machine blowing. Manual blowing, commonly known as “Blowing Big Bubble”, was introduced to China from Central Asia in the 5th century, stimulating and driving the development of Chinese glassmaking technology. Since then, Chinese began to use blowing method to make hollow glassware, i.e. glass containers. The way it works is that one end of a copper or iron blowpipe is dipped in molten glass, and then air is blown at the other end of the blowpipe to form the desired shape, and finally cut off with scissors.

During the blowing process, the technician must continuously rotate the blowing tube in order to prevent the glass melt from flowing out, using the viscosity of the liquid glass to shape it into the desired form. Coordination and cooperation must be done in between to achieve perfect products, thus making it quite difficult. The size, thickness, and shape of glassware depend on the size of air intake, degree of gentleness or speed of rotation of the tube.

In the process of “mold blowing”, compared with “free-blowing”, a hollow mold is first made of copper or iron, then glass molten liquid is sucked into the mold with a blowpipe and blown until it completely fills the inner wall of the mold. After cooling, the finished product can be demoulded. This process can produce special shapes such as square and polyhedral objects, and complex parts such as ears, mouths and feet. Mold blowing greatly enriched the shape and artistic expression of an object.

The purpose of glass teaware is to serve tea.

Mainly applicable to: grass flowers, black tea, green tea, Pu’er tea, fruit tea, health tea and crafts flower teas as well as coffee series with higher ornamental value and interestingness.

Learning

The surfaces of glass tea wares look quite transparent, but there is a big difference inside. Generally, the glass of genuine tea wares is even in thickness and very transparent under sunlight. It also makes a crisp sound when knocked. Most of them have gone through heat resistant treatment, so they won’t burst.

Although individual glass tea sets are relatively inexpensive, the sound of knocking is somewhat muffled and relatively turbid, and their heat resistance is average. Especially for glass teapots used to brew herbal tea, if the heat resistance is poor, the risk will be great!

2. Cleaning Method

Many people like to drink tea, but it is difficult to remove the tea stain on the cup. The layer of tea stain on the inner wall of teaware contains many metals such as cadmium, lead, iron, arsenic and mercury. When drinking tea, these metals enter the body and form insoluble precipitation with proteins, fats and vitamins in food, which hinders the absorption of nutrition. At the same time, these oxides entering the body can also cause diseases of nervous system, digestive system, urinary and hematopoietic system and functional disorders. In particular, arsenic and cadmium can cause cancer and fetal malformation, posing a threat to health. Therefore,tea drinkers should often and timely clean the tea stains on the inner wall of teaware. To help you avoid getting a headache for this matter , here are several ways to get rid of tea stains:

To remove the tea scale from a metal tea strainer, it may become dark and black due to the scale and cannot be washed away even with a medium cleaner. Soak it in vinegar or bleach to easily remove the scale.

Remove the tea stains from cups and teapots. When using for a long time, there may be a large amount of tea stains. Scrub with a sponge dipped in salt, which can easily remove them.

For small pieces of tea scale, soak them in a solution of bleach or cleaning powder overnight and it can remove the tea scale.

Rinse with water after scrubbing with toothpaste or crushed eggshells.

Method of Purchase:
1. Browse through available products or services.
2. Compare the different options to make an informed decision.
3. Place an order and pay for your purchase.
