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

So in the end, they regarded this kind of plant that was entangled with vines, fruits and fruits, as a constant reproduction and growth of human descendants, and also as a symbol of auspiciousness of having more children and blessings.

In our traditional culture, gourds, fruits and melons are also used by Confucianism, Buddhism and Taoism, and have become the embodiment of the yearning for peace, happiness and longevity.

Because the gourd bottle is homophonic with "Fu Lu" and the instrument has a character "Ji", it is also called "Da Ji" bottle, which means that the descendants will have great luck and good fortune, and both good fortune and fortune will be complete.

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

Therefore, in the late Ming Dynasty, it became a period when ceramic gourd bottles shone brightly, and their production also reached an unprecedented level of prosperity.

The varieties of this period were mostly blue and white and colorful, while among the shipwrecks in the Wanli period of the Ming Dynasty, the most common ones were found in blue and white gourd bottles.

There are now 3 gourd bottles in the domestic collection. However, this time, after going to sea, through the salvage of several wrecked ships, Chen Wenzhe found no 1,000 gourd bottles of all sizes, and there were also 800.

Among them are underglaze red gourds, and there are also colorful gourds, and the most common ones are blue and white gourds.

At this time, he saw that it was the blue and white gourd in Wanli of Ming Dynasty, and the patterns of this gourd were relatively similar.

The instrument has different shapes and sizes, round lips, slightly open mouth, long neck, waist, ring feet, and large gourd shapes on the upper and lower sides.

The neck is painted with blue and white banana leaf patterns for one week, and the upper abdomen is divided into six consecrated by double vertical lines.

The consecration is decorated with blue and white flowers and bogu patterns separated by bogu patterns, and a circle of blue and white flowers are painted at the waist, which serves as a partition belt between the upper and lower abdomen.

The lower abdomen is fan-shaped and the curves are like waves facing each other up and down.

The consecrated interior has blue and white floral patterns, separated from the dark Eight Immortals pattern.

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

Not to mention other works like this, as long as they can be preserved well and the blue and white glaze will not fall off, then seven or eight hundred Ming and Qing gourd bottles will appear in an exhibition venue all at once. What a shocking scene that would it be?

Unfortunately, it is really not easy to maintain the Haijiao porcelain.

Desalination is the basics and descaling is a must. In addition to the first time, the most important thing is to deal with the problem of glaze loss.

"Initial Evolution"

The glaze surface of Hailao porcelain has been soaked in seawater for a long time, and some matte or spot-like corrosion occurs.

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

Of course, most people definitely don’t know the formula of this solution, but Chen Wenzhe knows it.

As long as you have seen more antiques, or even visit the museum a few more times, you will definitely have seen porcelain restored by this method.

Others have seen it, but they just look at it, but they don’t know what they saw.

But Chen Wenzhe is different. He has seen it before, but now he can check some details through the Sui Hou Zhu.

For example, when repairing porcelain, there is a method to restore matt light, and there is a recipe for this solution.

If it were the original, this formula was optional for Chen Wenzhe.

But now it's different because he has too many sea-rapping porcelain in his hands.

If so many fine sea-rail porcelains from the Ming and Qing dynasties were not repaired properly, wouldn’t it be a pity?

However, he must not be able to repair so many fishing porcelains alone.

After the porcelain sinks to the bottom of the sea, the underwater creatures will inevitably go through the process of attachment, survival and death on the porcelain.

Afterwards, the porcelain was hit by the sea current and was eventually buried by mud and sand.

Therefore, the residual bodies of undersea organisms that can "parasien" on porcelain all have obvious characteristics of the times.

These residual bodies seem to be "dry" and "old", and there are basically no undersea biological remains that have just "moved to a new house" recently.

After hundreds of years, the residual bodies of the seabed biological that can "parasien" on porcelain have been completely calcified.

Some have become fossil-shaped and have no freshness.

If you open the remaining bodies of individual seabed biological organisms, you will find that the degree of calcification inside and outside is the same, the color is basically the same, there is no odor when you smell it, and there is basically no acute angle or particularly prominent parts.

But there are also special circumstances. Some porcelains fall into the cracks of rocks or coral reefs under the sea, and are less affected by the impact of sea currents and silt.

Some undersea creatures, such as corals, can also grow into certain shapes on porcelain.

Porcelain comes from porcelain clay and has a good physical affinity with calcium carbonate minerals.

Seawater contains a large amount of calcium carbonate minerals. The movement of the current and temperature changes will cause these salt substances in the seawater to gradually gather on the surface of the porcelain and deposit.

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

Some sediments attached to the porcelain glaze are not firm, and you can also scrape off parts with your nails after they are released from water.

Using the principle of permeation, soak these porcelains in dilute salt water for several days.

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

Some of them are attached to more firm subsea biological residues and are cleaned with an ultrasonic cleaning machine. They can generally be cleaned.

But this job is really troublesome.

It is not just the quantity, even if there is only one piece of haystack porcelain, it is not easy to deal with.

For example, before starting desalting and repairing of the porcelain from the water, the broken slag mouth, and the cracks, the various dirt and impurities in the surface of the porcelain must be cleaned and removed.

This will provide good conditions for subsequent protection and restoration processes.

After that, whether it is cleaning soap liquid, mechanical removal, or cleaning with chemical solution, the basic principle should be based on the non-harm of the instrument.

If you are not sure about the method you plan to use during the implementation process, you must first conduct relevant experiments on alternatives such as the same type of broken ceramic pieces.

After reaching the conclusion, it will be implemented on the porcelain objects to be repaired.

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

Then rinse it in clean water, use a boar bristle brush to dip it in soap powder, and finally rinse it with warm water.

For those stains that penetrate deep into the body through the damaged glaze layer, they intuitively present the unique traces of Hailao porcelain. In the purpose of respecting historical information, they are appropriately retained to reflect their historical authenticity and readability.

For those porcelain that have been repaired by non-professional personnel and must be removed and washed and repaired, first immerse the original adhesive and repair part in acetone for three to five hours, dissolve the filling line, and bond the broken 502 glue.

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

The dirt in the mouth is rolled into strips with cotton and poured into concentrated nitric acid with a dropper.

The saturation level is 80%~90%, apply it on the punch, then seal it with plastic film, and open it the next day to remove it.

As I said that, it is not difficult to repair and maintain the seaside porcelain, but it is rare that it is too large.
