How do you repair broken porcelain? Methods for repairing cracks in porcelain

The art of restoration by the real filmmaker:A teapot with more than 200 nails.

On October 22, 2017, Zhengzhou, "curium porcelain" is an ancient handicraft in China, and the world knows the phrase "no diamond, don't do porcelain work".

It comes from the curium porcelain industry. To put it simply, the broken porcelain is nailed with copper, iron, tin and other metal nails so that the porcelain can be repaired and reused.

In modern times, due to the development of society, the general porcelain is broken and thrown away, and slowly the industry is declining, and the curium porcelain process is gradually lost. However, there are still a few who are still holding on. Chen Ying, a 32-year-old Xinxiang native.

Since childhood, I like traditional Chinese handicrafts, four years ago because I saw the curium porcelain craft in Beijing and was deeply attracted, and then devoted himself to the study of curium porcelain craft in his spare time.

On October 22, when he met Chen Ying in a cramped studio in Zhengzhou, he was carefully holding a friend to him to entrust him with the repair of a broken lid. Chen Ying first used a pen to draw the position of the hole that needs to be punched on both sides of the broken lid, and then carefully drilled two small holes with a hand drill, and gently knocked it flat with a small hammer in the two small holes with a thin copper strip, and finally filled it with powder and polished.

This teapot, which was once broken, Chen Ying had to repair it with more than 200 nails in total.

Chen Ying saidA piece of broken porcelain has to go through the processes of finding ballast and seams, punching, nailing, nailing, grinding, and filling powder, which takes as little as four or five hours, and two or three days for complicated ones。Now some people come to curium porcelain is not the value of the utensils, but the feelings for the utensils, so we must be careful and meticulous when repairing, so there can be no mistakes. Chen Ying jokingly said that our line of work can be said to be "repairing emotions".

I am very satisfied when I see the joy on the faces of customers when they come to pick up their orders. I hope to pass on and carry forward this handicraft that is facing gradual decline and extinction, which contains rich cultural connotations.

First, use green onions, mash them into juice, and glue the porcelain fragments with sticky green onion juice, do not shift after fixation, and stand still for at least 24 hours.

Second, use egg whites, also fixed after not moving for at least 24 hours.

If the craftsmanship is good, there are almost no traces to be seen, and these methods were used by ancient craftsmen.

It's just that the repaired porcelain must not be wet, otherwise... You can guess.

It's not that I'm talking nonsense, this is what I listened to Mr. Ma Weidu, and then personally repaired a broken rice bowl, which is very easy to use, of course, I don't dare to use it after repairing, and I have the right to be a reward.

Porcelain crack repair method, the specific steps are as follows:

In real life, when we use ceramics, what glue can be used to glue ceramics?

1. What glue can stick to ceramics.

If the ceramics are broken, they should be glued together with AB glue, which is very fast and the overall recovery effect is also very good after drying. After bonding, although there will be a certain mark on the overall surface, the overall bonding will be relatively complete. Moreover, AB glue is used in a wide range, it can be repaired and joined, as well as pouring and potting and so on.

We can also use marble glue to glue the ceramic, which should be used with a quick-setting agent. However, this glue is more professional and difficult to find. It can also be pasted with instant adhesive 101 or AB glue, but the effect is not as good as marble glue.

Second, how to maintain ceramics.

Ceramics are fragile and should be handled with care when using them. We can't put it the table, and it is best to hold it with both hands when we take the ceramics, so that there will be no slipping hands, so that the ceramics fall and break. When you put it, you should also hold it with both hands to place, and it is not possible to put the ceramic at the tuyere, if the ceramic is blown down by the wind, it is easy to break.

And it is easy to have dust on the ceramic, so it is necessary to clean its surface regularly. And when wiping the dust on the surface, you should wipe it with a soft cloth, and the force should be light, and you can't wipe it hard, so as not to damage its surface. If it is dirty and cannot be wiped off with a cloth, it cannot be forcibly wiped.

Be sure to use a special item to remove the stain from it, so as not to forcibly wipe the ceramic and make its surface scratched. In addition, it is possible to forcibly wipe the ceramic, and there will be cracking.

1. Wipe the broken place with paper first.

2. Buy a bottle of AB glue, which is generally sold in the market. This glue has a particularly good adhesion and can be bonded quickly.

3. Pour out some A glue first, then pour a little B glue, and mix thoroughly with a tool.

4. Glue both sides of the broken surface.

5. Paste and press the two sides tightly.

6. Use paper to remove the excess glue.

7. After natural air drying, the porcelain bowl has returned to its original state, although it cannot be intact, but at least it can be used, and it feels very fulfilling.

Materials required: raw lacquer, black lacquer, egg whites or glutinous rice flour, gold leaf.

Gold repair tools: knives, sandpaper, pens, hair dryers, electric kilns, utility knives.

Practice steps: 1. Fix the tire with raw lacquer, coat it on the ceramic section, and bake it in the kiln.

2. Prepare glued lacquer, two formulas: black lacquer plus protein, or black lacquer plus glutinous rice flour.

3. Stir until the paint becomes viscous, and stir with a hair dryer while heating to accelerate the reaction.

4. The ceramic section is coated with glued lacquer.

5. Glue the pieces tightly together.

6. The state after the bonding is completed.

7. Fill the surface gaps between the fragments: small cracks, fill them with glutinous rice and lacquer blending paste; Large seams, which can be filled with wood powder paint or lacquer line drawings.

8. After filling is completed, polish it with sandpaper.

9. Apply a layer of red paint to the cracks.

10. After the paint is half dry, cut the gold leaf to a suitable size, and paste the gold leaf on the lacquer.

11. a finished product.

Hello, it's better to stick with 502, the good penetration of the two brothers is relatively poor, or it is easy to break and there will be a certain gap in the middle. A wash the ceramic pieces and dry them without too much dust, b use 502 to bond them in the crushing out, and quickly glue them (dry relatively quickly), c After gluing, leave them for a period of time to ensure that they are completely dry.

d Mix the gypsum and water evenly for use (note: pour a certain amount of water into the container first, and then add the gypsum slowly, otherwise it is easy to produce bubbles, the ratio is basically 1:1, put it for half a minute to let the air in the gypsum run out and then stir it quickly).

When the gypsum is paste-like, the adjusted gypsum is picked on the damaged part with a hacksaw blade, and the plaster is carefully patched, paying attention to making up more than the original type, so as to facilitate the next operation.

f Leave the repaired model for 5 minutes, and when the surface of the plaster is hot, hang off the higher part of the plaster with the sawtooth surface of the hacksaw blade, and then dimmer it with sandpaper and polish it smooth together with the traces left by 502.

g Place the repaired porcelain in a cool, dry place for 4 to 5 days until the plaster is completely dry.

h First mix acrylic paint into a color similar to the glaze and apply it to the plaster surface until the acrylic is completely dry. Great success.

In addition to applying acrylic paint, the above steps are the repair steps of cultural relics, in fact, not to draw acrylic is also very good-looking, there is a sense of vicissitudes, very temperamental, you might as well give it a try.

To see what porcelain, it is necessary to repair no, because the repairer is very expensive. I'm a professional in restoration.

Tools: lacquer, some glutinous rice flour, turpentine.

1. First of all, we prepare a cracked porcelain.

2. Mix lacquer, glutinous rice flour and turpentine.

3. We have to stir and stir until they become sticky. Wait until you can hold the stirring stick like maltose. If it is too thin and not sticky, it will not work, and this step must be stirred carefully. The gelatinous substance we have prepared is then applied to the broken fractures.

4. Then glue the notch. It is best to stick the adhesive fracture with adhesive tape, otherwise it will crack on its own later.

5. Put our repaired sub-finished product at the vent, wait for the paint to dry, and wait for a long night, you can tear the adhesive tape. Continue to wait for about ten days. Scrape off the excess paint next to the repaired crack with a knife, or gently polish it with sandpaper.

6. Then use red paint to trace along the seam, dilute the red paint with turpentine and apply a very thin layer is enough, and after ten minutes, when the surface is semi-dry, brush with gold powder with a brush. Then we gently wiped off the excess gold dust and the repair was successful.
