My system is not decent

Convenient tools, especially for primitive ancestors, are more important.

So in the end, they regarded this kind of plant with entwined vines and continuous melons and fruits, as a kind of auspicious symbol of many children and many blessings.

In the traditional culture of our country, the gourd is also used by Confucianism, Buddhism and Taoism, and has become the embodiment of yearning for peace, happiness and longevity.

The gourd bottle is also known as the "Daji" bottle because it has a homonym with "Fulu" and the image of the vessel is "Ji".

During the Jiajing and Wanli periods of the Ming Dynasty, because the emperor advocated Taoism, most of the arts and crafts were decorated with auspicious and wishful patterns.

As a result, the late Ming Dynasty became a period when ceramic gourd bottles shined brilliantly, and its production also reached an unprecedented level.

Most of the varieties in this period were blue-and-white and multi-colored, and in the shipwrecks of the Wanli period in the Ming Dynasty, the blue-and-white gourd bottles were generally found the most.

Now there are 3 gourd bottles in domestic collections, but only this time when he went to sea and salvaged several sunken ships, Chen Wenzhe discovered not one thousand, but eight hundred gourd bottles, large and small.

Among them, there are red gourds in glaze and multicolored gourds, and the most common ones are blue and white gourds.

At this time, he saw that it was a Ming Wanli blue and white gourd, and the decoration of this kind of gourd was relatively similar.

The shapes and sizes of the utensils are different, with round lips, slightly open mouth, long neck, waist, and ring feet, in the shape of a small gourd at the top and a big gourd at the bottom.

The blue and white banana leaf pattern is painted on the neck for a week, and the upper abdomen is divided into six openings by double vertical lines.

The consecration is decorated with blue-and-white flowers and Bogu patterns, and a circle of blue-and-white flower patterns is painted on the waist, which serves as a separation belt for the upper and lower abdomen.

The lower abdomen is consecrated in a fan shape, and the curves are like waves upside down and opposed to each other.

The blue and white floral pattern on the consecrated interior is separated from the dark eight immortals pattern.

The blue and white hair color is blue, the carcass is thick, the lines are smooth, and the design is exquisite.

Such works, not to mention other things, as long as they can be preserved well, and the blue and white glaze color will not fall off, then seven or eight hundred Ming and Qing gourd bottles will appear in an exhibition hall at once, what a shocking scene it will be ?

Unfortunately, the maintenance of hailao porcelain is really not easy to do.

Desalination is basic, and descaling is a must. Apart from the first time, the most important thing should be to deal with the problem of glaze loss.

"First Evolution"

Due to the long-term immersion in seawater, the glazed surface of Hailao porcelain appears partially matte or corroded in spots.

However, it can now be repaired with a solution, which means that after soaking, the glaze can be restored.

Of course, ordinary people definitely don't know the formula of this solution, but Chen Wenzhe does.

As long as you have seen more antiques, or even visit museums a few more times, you will definitely have seen porcelain restored in this way.

Others have seen it, that is, glanced at it, and don't know what they saw.

But Chen Wenzhe was different. He had seen it before, but now he can check some details through Sui Hou Zhizhu.

For example, in the method of restoring porcelain, there is a method of restoring matte, and there is a formula for this solution.

If it is the original, this formula is dispensable to Chen Wenzhe.

But now it is different, because he has too much hailao porcelain in his hand.

Wouldn't it be a pity if there are so many fine Haidao porcelains from the Ming and Qing Dynasties that are not properly repaired?

However, repairing so many hailao porcelain is definitely not something he can do alone.

After the porcelain sinks into the bottom of the sea, the sea creatures must go through the process of attachment, survival and death on the porcelain.

After that, together with the porcelain, it was impacted by the ocean current and was finally buried by sand.

Therefore, the remains of submarine organisms that can "parasitize" on porcelain all have obvious characteristics of the times.

These remnants look "dry" and "old", and there are basically no remains of underwater organisms that have "moved to a new home" recently.

After hundreds of years, the remains of submarine organisms that can "parasitize" on porcelain have been completely calcified.

Some have become fossil-like and have no freshness.

Open individual seabed biological residues and observe, you will find that the degree of calcification inside and outside is the same, the color is basically the same, there is no peculiar smell, and there are basically no sharp angles or particularly prominent parts.

But there are also special cases. Some porcelains are less affected by the impact of ocean currents and sediments because they just fall into the seabed rocks or crevices of coral reefs.

Some underwater organisms, such as corals, can also grow into certain shapes on porcelain.

Porcelain is derived from china clay, which has a good physical affinity with calcium carbonate minerals.

Seawater contains a large amount of calcium carbonate minerals, and the movement of ocean currents and temperature changes will cause these salts in seawater to gradually gather on the surface of porcelain and deposit them.

Because of the glaze layer on the surface of the porcelain, it is hard and smooth.

Some deposits attached to the enamel are not firm, and some of them can be scraped off with nails after the water comes out.

Using the principle of osmosis, these porcelains are soaked in dilute brine for several days.

Those salt deposits on the surface of the porcelain will gradually peel off.

Individual seabed biological residues with strong attachment can be cleaned with an ultrasonic cleaner, and generally can be cleaned up.

But this job is really troublesome.

Not only because of the quantity, even if there is only one piece of hailao porcelain, it is not easy to handle.

For example, before starting desalination treatment and restoration of out-of-water Haidao porcelain, it is necessary to first clean and remove all kinds of dirt and impurities on the surface of the porcelain, broken ballast, and cracks.

Only in this way can we provide good conditions for the implementation of the subsequent protection and restoration process.

Afterwards, whether it is cleaning with soap, mechanical removal, or chemical solution removal, the basic principle should be to not harm the utensils.

If you are not sure about the planned method during the implementation process, you must first conduct relevant experiments on substitutes such as broken porcelain pieces of the same type.

After drawing a conclusion, implement it on the porcelain object to be restored.

For ordinary stains on underglaze porcelain such as blue and white and Longquan, it must be soaked in diluted alkaline solution, and the concentration and time depend on the stain.

Then rinse with water, gently scrub with a bristle brush dipped in soap powder, and finally rinse with warm water.

For those stains that have penetrated into the carcass through the damaged glaze layer, visually presenting the unique traces of Haidao porcelain, in line with the purpose of respecting historical information, they are properly preserved to reflect its historical authenticity and readability.

For those porcelains that have been repaired by non-professionals and must be dismantled, washed and repaired, first immerse the original repaired part in acetone for three to five hours, and dissolve the 502 glue that filled the punching line and bonded the damage.

Then immerse it in hot water and add a little alkali. Generally, it only takes 10 to 20 minutes, and the bonding will automatically fall off.

The dirt in the mouth is rubbed into strips with cotton, and concentrated nitric acid is injected with a dropper.

The saturation degree is 80%~90%, apply it on the mouth, seal it with plastic film, and remove it the next day after unsealing.

Having said that, it is not difficult to clear, repair, and maintain hailao porcelain, but the rare thing is that the number of them is too large.
