What is glass Is it worth anything and is it heavier than jade

Glaze is a kind of colored pottery used in architecture and art decoration. A work of art made from artificial crystal of various colors (containing 24% lead oxide) and sintered at high temperature using crystal wax casting. This process requires dozens of meticulous manual operations to complete, and the slightest negligence can cause failure or flaws.

Glazed products are colorful, simple in shape, reasonable in structure, rich in the traditional national characteristics of our country, and resistant to wind and rain erosion, not easy to fade and peel off the glaze, used to build pavilions, platforms, floors, pavilions, it is particularly majestic and magnificent. The beauty of the glaze is like jade, incorporating creativity and ingenuity, not only traditional, but also modern Chinese cultural characteristics, so that the glaze can play a bright role and create a colorful beauty of life art. Chinese glaze is the perfect combination of ancient Chinese culture and modern art, its brilliance, change magnificent, is the exquisite, delicate, subtle embodiment of the Oriental people, is the fusion of thought, emotion and art.

Liuli is an ancient Chinese material, its use has a history of 2467 years, since ancient times has been the exclusive use of the royal family, there are extremely strict grade requirements for the user, so the folk are rare.

Liuli is known as the first of China's five famous vessels (gold and silver, jade, glass, ceramics, bronze), one of the seven treasures of Buddhism, to the Ming Dynasty has been basically lost, only in the legend and gods and monsters ** recorded, "Journey to the West" in the sand monk was demoted to heaven because of breaking a glass cup.

However, even the very incomplete craftsmanship of the Ming Dynasty is still protected by the grade, and the glass at that time was already very impermeable, so it was called medicinal jade. "Ming System" contains: The ornament awarded by the emperor to the champion is medicinal jade, and it is equipped with more than four grades.

Home is to the daughter, the residence official is to the prime minister, a passage in the "Historical Records" is related to the origin of the glass. ("Xi Shi Tears" omitted), Tao Zhugong is the god of wealth in folklore, the earliest cornucopia of the god of wealth in the legend, is also made of glass, so the glass is considered to be the god of wealth and blessings of the God of Wealth token, more direct and effective than the citrine commonly used by people.

Glass is artificial glass, while jade is a natural stone, which can be turned into jewelry by hand such as manual mining and polishing.

are two completely different materials.

Identification method 1:

The quality identification of ancient glaze can refer to jade, and there are six standards, namely "color, transparency, uniformity, shape, knocking, and illumination".

1. The color of the glass is gorgeous, and the surface light can be discerned and colorful; The surface of the glass with poor color is dull, and the gloss and brightness are poor.

2. Good glass transparency, different angles have different viewing effects; And the poor quality glass is not transparent.

3. The "uniform" in the identification of uniform glass refers to the transition between different colors of the glaze, and the transition of good glaze is symmetrical; The color transition is stiff, and the appreciation value and collection value of the glass are poor.

4. The grace of the shape of the glass determines the value of the glass, and the glass with beautiful shape and good workmanship is the top grade.

5. Knock two pieces of glass and tap each other, there is the sound of gold and jade, and the more crisp the sound, the better the quality.

6. Under the irradiation of ordinary lights, the high-quality glazed glass is graceful and colorful, shining brightly; The color difference of the glass reflection is not beautiful enough.

Identification method 2.

The key to appreciating glass:

1. Glass is completely different from crystal and glass. What is the difference between glass and crystal (Western crystal glass).

a. There is a clear distinction in the history books.

There is a similar record in the Diamond Sutra. In all the Buddhist scriptures in China, the first five categories of the Seven Treasures of Buddhism are recognized, namely gold, silver, glass, and clams * a mollusk * agate, and the latter two categories are said to be crystal, some are said to be crystal, some are said to be amber, glass, and so on, which shows that glass is recognized as a Buddhist treasure; Glass is very different from crystal and glass.

b. The chemical composition is different.

The main components of natural crystal, glass and glass are silica, and the authoritative monograph "Research on Ancient Chinese Glass" records that the proportion of silica in ancient Egypt "Fionce" (that is, the ancestor of Western crystal glass) is 92% (impermeable) -99%, and the proportion of silica in the glass of the Zhou Dynasty in China is only slightly greater than 90% (transparent). This 9% difference is the biggest difference between glass and crystal.

c. Detailed explanation of ingredients.

Ancient glaze is made of glazed stone to add glazed mother, glazed stone is a colored crystal material, the main ingredient should be silica-based, glazed mother is a natural and artificially refined ancient formula, can change the structure and physical characteristics of crystal, in shape, color and transparency are obviously different. The medicinal jade of the Ming Dynasty should be a little different in the formula of the glazed mother, so the color of the medicinal jade of the Ming Dynasty is less variable and not transparent. The grade of the glaze actually depends on the raw materials and preparation methods of the glaze mother, which is a secret that has not been passed down since ancient times, and it is precisely because of the existence of the glaze mother that the ancient Chinese glaze and the crystal and even the Western crystal glass "Fians" have a 9% difference in composition.

I think glass is worth money.

The reason for the value of glaze is that the ancient glaze material is special, and its production process is quite complex, glaze is not only a material, but also a cultural product, glaze production has a long history, famous at home and abroad. Its exquisite craftsmanship and profound cultural connotation are important members of traditional Chinese handicrafts. Liuli is known as the first of China's five famous vessels, and it has been basically lost in the Ming Dynasty.

Ruri introduced

Colored glass, also known as "ruli", is a rare ornament made of artificial crystal (containing 24% lead dioxide) of various colors (the color is produced by various metal elements) and fired at a high temperature of more than 1,000 degrees. Its color is colorful, and the quality is crystal clear and dazzling.

The first material used to make glaze in ancient China was obtained from the by-products produced during the casting of bronzes, which were refined and processed to make glaze. There are many colors of glaze, and the ancients also called it "five-color stone". In ancient times, because it was difficult for the people to obtain, people at that time regarded colored glass as even more precious than jade.

In June 2008, the glaze firing technique was selected into the second batch of national intangible cultural heritage list approved by the Ministry of Culture. The glaze on the market is mainly dewaxed glaze represented by the south and handmade glaze represented by Boshan (Zibo). The more famous teams of domestic glaze production are glaze workshop, Renli glaze, Liuyuan, etc.

Glazed jade is a kind of glaze, which does not belong to jade, but only represents that this kind of glaze is more transparent and as exquisite as jade

Its material is made of artificial crystal of various colors (the color is produced by various metal elements), which belongs to industrial synthesis, (containing 24% lead dioxide) as raw materials, and the temperature requirement is more than 1000 degrees Celsius of high temperature firing into rare ornaments. Its color is brilliant and colorful, especially dazzling, which makes people love it, crystal clear and dazzling. In the beginning, it was obtained from the by-products produced during the casting of bronzes, and the leftovers of refining were processed and then made into glass.

The color of the glass is varied, it is never a single color, giving people a sense of visual impact, and the ancients also called it a five-color stone.

If you are helpful, remember to give a thumbs up

Glaze is known as the first of China's five famous vessels (gold and silver, jade, glaze, ceramics, bronze), one of the seven treasures of Buddhism, to the Ming Dynasty has been basically lost, only in the legend and the gods and monsters ** recorded, glaze is considered to gather wealth and fortune of the God of Wealth token sail Qi, more direct and effective than people commonly used citrine.

The refraction of light from different angles and colors of glass can present a three-dimensional visual effect. The clarity of the glass needs to have a certain level and the difference in finish, otherwise it will lose its dynamic vitality.

From the perspective of craftsmanship, appreciate the national culture and structural characteristics contained in the ancient glaze. The ancient process determines that there are no two pieces of exactly the same glass in the world, and if you carefully taste the color flow of different glass, you will find different artistic conceptions.

The hardness of colored glass is relatively strong, which is equivalent to the strength of nephrite. But it is also more brittle than the state tomb, can not be slapped or collided hard, the glass can not be collided or rubbed to move, so as not to appear surface scratches can not be heated or cooled, the plane is smooth, should not be placed directly on the desktop, it is best to have a gasket. It is advisable to wipe with pure water, if tap water is used, keep the gloss and cleanliness of the surface of the glass, do not stain with oil stains, and avoid contact with sulfur gas, chlorine, etc.
