Of course, in addition to the above processes, there are other processes.

For example, apply a layer of white glaze on the utensil as ground glaze, and apply a thinner green glaze containing copper oxide to the white glaze, and fire at a high temperature in an oxidizing atmosphere.

This type of green glaze utensil has never been well known to people in the past.

In previous archaeological excavations, so-called "white glaze and green color" objects from the late Tang Dynasty to the Northern Song Dynasty were found in many kilns in the northern region.

From this we can actually see that the porcelain of the Song Dynasty played a role in connecting the past and the future.

There were not many colored glaze porcelains in the Song Dynasty, and they were generally monochrome glaze, such as celadon and white porcelain.

At most, there are some green glaze, black glaze, and sauce glaze porcelain.

At this time, Chen Wenzhe suddenly realized that when he was making green glaze porcelain in Nanyue, it seemed that he had not finished it.

For example, the white-glazed green-colored porcelain from the Northern Song Dynasty seemed to have not made it.

Or when he did this, he was distracted, attracted by other porcelains, and turned to other porcelains.

Now he is idle and has nothing to do, so he naturally wants to find something to do.

So, he started with low-temperature glaze. If possible, he wanted to burn all the five famous kilns of the Song Dynasty.

It is not easy to re-fire the five famous kilns, but starting with low-temperature glaze, it is not difficult to fire some green-glaze porcelain first.

The so-called "white glaze and green color" utensils have the same production method as the above-mentioned process flow.

It is just that the green color on most of the utensils is only used as patterns on small areas in some areas.

For example, in the excavation of the Cizhou Kiln site, white-glazed green incense burners, bottles, jars and other utensils unearthed from the earliest strata, only some green color spots were decorated along the surface and belly of the utensil.

However, in the early strata of the Yaozhou Kiln in Tongchuan, Xishan, more white-glazed green-colored porcelains were found in Hehusha Kiln.

Moreover, some utensils decorated with green color spots are large, covering most of the surface of the utensils. These utensils are burned at one time at a high temperature.

It can be seen that there is basically no problem in the process when applying green color to the white glaze in one go.

As for the firing temperature, whether it is lower than ordinary white-glazed porcelain, it is still unknown because there is no good test data.

The best example is the porcelain from the Tang Dynasty Black Stone shipwreck that salvaged water from Belitung Island in recent years on the coast of Indonesia.

It was found from this wreck, which carries porcelain from the second year of Baoli in the Tang Dynasty (826).

The age when this ship sank is probably not much later than this year.

More than 60,000 pieces of porcelain were found in the Black Stone, including hundreds of white-glazed green-colored porcelain produced in the northern region.

These porcelains have large areas of green color spots, which are scattered and flowing, covering most of the watches.

When the green glaze on the instrument table is sufficiently large, green covers the entire instrument table and becomes green glaze porcelain.

A piece of Wanwan's private collection is considered a green glaze bottle for products from Gongyi Kiln in Nanhe. The upper part of it can be called a green glaze utensil, but the application method of green color spots can also be seen on the abdomen.

This utensil is a very good example of the dense green color spots that turn into green glaze utensils.

The characteristic of this type of green glaze utensil is that the green is relatively shallow, light and bright.

Among several green glaze utensils, the colors are the most beautiful and bright.

However, green obviously has unevenness and is generally thin.

At present, this type of green glaze utensil was mainly found in the late Tang Dynasty, but some kilns in Cizhou Kiln and in the central and western regions of Nanhe.

White-glazed green-colored porcelain produced by Xinmixiguan Kiln and Hebi Ji Kiln were very popular in the early Northern Song Dynasty and continued to be produced until the late Northern Song Dynasty.

Therefore, it should be reasonable to use this method in the late Northern Song Dynasty to produce green glaze utensils.

In 2005, the Shendu Cultural Relics Research Institute once again excavated the Liao Dynasty Longquanwu Kiln site located in Mtg District.

Among the unearthed objects in the late Liao Dynasty strata, green glaze porcelain pieces were found with the same glaze as this green glaze plum vase.

This became a good example of this green-glazed porcelain that continued its production until the late Northern Song Dynasty.

In the past, I didn’t know whether Ding Kiln produced such green glaze utensils. Later, there was a plum vase, which could be used as a reference for the production of such green glaze porcelain by Ding Kiln because of the reliable test data.

The colorant of the green glaze is copper oxide, and lead compound is a low-temperature lead glaze (800-1000°c) that is secondary to the kiln.

Generally, the vegetation is first burned and then the glaze is hung on the low temperature to roast.

Green glaze products fired in Ding Kiln have been mass-produced from the middle and late Tang Dynasty to the end of the Jin Dynasty, and have a very rich variety of instruments.

The firing of green glaze may have evolved from the inheritance of Tang Sancai technology.

The Dingzhou Museum now has a complete Ding kiln green glazed carved pillow in the Jin Dynasty that belongs to the Cizhou kiln style. The pillow is thick in body, gray-black, and the patterns are typical of Ding kiln style.

The site specimens show that a small number of green-glazed Ding Kiln products are available, with a variety of exquisite decorations such as engraving, printing, and stacking, and most of them are smooth and patternless.

In the early days, all cosmetic soil was used, which was light green and green, pleasing to the eye, slightly different from the color of other kilns.

When filling, three-stitch nails, pads and mud rings are mostly used, and no overlying the burnt-mouth variety is found.

Ding kiln green glaze should be a low-temperature glaze about 800°C that is fired in the second kiln.

But in terms of their fetus, we have never seen a product above 1100°C.

The reason is that the boundary of the green-definite burner must have a certain water absorption rate to ensure the adsorption capacity of the glaze water.

At that time, the Ding kiln firing technology could not solve the secondary glaze problem of 1250°C high-temperature plain firing blank.

Furthermore, high-temperature flaves are also very easy to break when they are re-burned.

Taking into account a variety of factors, there was no high temperature green fixed at that time.

Even if it exists occasionally, it is just a small number of test products and immature products.

Therefore, due to the limitations of technology at that time, there was no formal production of Ding kiln varieties with green glaze high-temperature porcelain body.

In the Song Dynasty, only Xiguangrong County fired high-temperature green glaze porcelain.

Green-glazed pottery is mostly fired in kilns in the north and south.

At the Ding Kiln site, especially in Yanchuan District, low-temperature green-glazed pottery, there are many people.

Among the many green glaze ceramic fragments of Ding kiln, very few are indeed characterized by Ding kiln-style carving, thin body and white body.

However, compared with the high-temperature white and white tires, there is a significant distance.

The origin of Ding Kiln green glaze,

From the perspective of origin, Han green glaze, Southern and Northern Dynasties multi-colored lead glaze, Sui green glaze, Tang Sancai, and Song green glaze should have inheritance relationships.

Han green glaze is also a low-temperature lead glaze, but the glaze color is single, with only two types of green and yellow.

Generally, it is glass glaze, and some glaze colors have poor transparency.

After more than two thousand years of ground temperature and ground pressure, as well as water and soil soaking, most of the glaze layers have changed.

Therefore, silver-white crystals precipitated on the glaze surface after it was unearthed, which is known as silver glaze.

There are fewer glaze patches.

After the multi-colored glaze of the Southern and Northern Dynasties and the further development of green glaze of the Sui Dynasty, the colorful Tang Sancai formed in the Tang Dynasty.

Tang San was colorful, with transparent glaze, fine and fragmented, and the body was also more solid than the Han Dynasty.

Tang yellow glaze porcelain appeared in Ding Kiln system, with fine body and transparent glaze, and cosmetic soil was used.
