Repair method of fine cracks

1. Cook some glutinous rice porridge first, and then put the porridge in the pot.

Boil the pot with boiling water, put the pot full of glutinous rice porridge into the pot and steam for 10- 15 minutes, so that the porridge water can fully penetrate into the gap.

Out of the pot, pour out the glutinous rice porridge, don't rinse it, then steam it in the pot for 5 minutes, let the porridge water in the gap solidify, and rinse it with water.

After the electric oven is preheated with fire, put it into a pot and bake it for 5 minutes with medium fire, so that the porridge water in the crack is dehydrated and coked, and the two sides of the crack are bonded. It can be used after being cleaned again.

If the microwave oven is used, the baking position should be adjusted slightly longer (about 6 minutes) and the fire power should be adjusted to 250 C. In addition, you can also use the simplest one-button rice cooker, put a metal frame at the bottom of the pot in a dry state, put it into the pretreated pot (step 1-3), cover the pot cover, and press the cooking button to make the pot heat up and control it. At this time, do not open the lid immediately, and bake for 1-2 minutes by using the temperature in the pot.

Second, the large area crack repair method

Cleaning the teapot: first, wash the dust roughly with clear water, and then use a brush and a knife to clean the tea scale and broken mouth with toothpaste and water. If some tea stains are difficult to clean with purple sand, you can soak them in bleach and other solutions for about two hours.

Bonding teapot: According to the shape, decoration and color of teapot, try to arrange it, write down the marks with a pen and plan the bonding order. The choice of adhesive for porcelain restoration is the key. Because some teapots are seriously damaged, the performance requirements of adhesives are high. Only by choosing an adhesive with high bonding strength, strong anti-aging ability and moderate curing time can we repair a high-quality teapot.

At present, AAA super adhesive is mostly used to bond teapots, which has the advantages of colorless, transparent and fast curing. Add pigment with the same color as glaze to AAA glue, and smear it on the fracture for butt joint. Bonding is a difficult process to repair teapot. When operating, we should follow the pre-determined plan and give consideration to both the upper and lower levels. Many fragments can be bonded from the bottom, and some can be bonded from the mouth. Everything must be error-free One piece was misplaced, and finally it won't close tightly. Be careful not to apply too much glue when bonding. Apply the glue to the center of the purple sand piece, press it when combining, and tie it with a white cloth belt. Wipe off the spilled glue with acetone immediately.

Repair the damaged parts of the teapot: For the damaged parts of the teapot, use purple sand powder and AAA glue with similar colors to repair them. And choose the appropriate method according to the damage degree of the teapot. For example, the spout or handle can be repaired as it is, and a new one can be burned to make the same patina as the original porcelain. After the old one is finished, add AAA glue to make it up and stick it on the purple sand.

Matters needing attention

Whether you use an electric oven, microwave oven or rice cooker, don't wash the pot with water immediately after taking it out. Wait for the pot to cool before washing it, so as to avoid expanding with heat and shrinking with cold.

When cooking glutinous rice porridge, you can make it thicker. Before the third step, you can take out the cooked glutinous rice grains in the porridge and grind them on the gap between the inner and outer walls of the pot to increase the viscosity.

Several methods for repairing cracks in teapots are introduced in detail.

Several methods to repair cracks in teapot: Does teapot have cracks and leaks? If it doesn't leak, it doesn't need to be repaired. If it leaks, of course it will be repaired. The place where the teapot touches the water cannot be bonded with glue such as 502 and AB glue, which will pollute the water. You can try several repair methods introduced by the following basin friends: 1, and put the egg white on the section and then stick it, which is environmentally friendly, seamless and very firm. 2. Grind the old blue tiles in the south of the Yangtze River into powder, wrap them in gauze, and wrap them in 6 layers, the size of apricots. In the process of drinking tea, gently wipe the tea juice while it is hot. Over time, you can not only get rid of old injuries, but also raise pots. 3. Boil the cracked porcelain in milk for half an hour, and the protein in the milk can seal the small cracks. It can not only block the cracks, but also keep the original surface texture of porcelain to the maximum extent. 4. If there are big cracks in porcelain, you can try the following methods: mash several snails with shells into slurry, embed them in the cracks in porcelain, and use them normally after drying in the shade. 5. You can also try the following self-made bonding material: 100g milk, slowly add vinegar while stirring, then take half an egg white, add water and stir evenly, then add a proper amount of quicklime powder and stir it into a paste, which can be used to bond pottery fragments. For broken ceramic utensils, tie them tightly with a rope after bonding, dry them slightly, bake them slightly, and cool them until they are firm. 6. You can add glutinous rice (or japonica rice) porridge soup and cook it on the stove with slow fire for about 1 hour, so that the starch in the water can penetrate into the gap of the casserole. The boiling casserole should not be placed directly on the concrete floor from the fire, but on a wooden or iron tripod, otherwise it will crack due to uneven cooling. Clean joints or broken parts.

What if the teapot is cracked?

Just find a "pot saw" master to saw a few small nails. It will become another decorative style after sawing, and it will not affect the use and enjoyment. Such a pot itself should be of certain value, at the level of master or above, or of special significance to you and worth collecting.

I stirred a small pot in my hand and my mouth broke, so I found a pot saw to repair it, and it is still in use.

There is a crack in the teapot. How is it caused?

Maybe it is production, maybe it is production, maybe it is production.

How to deal with slow seepage caused by fine cracks in teapot?

I'll answer this question. Zisha pots are all made at home, and occasionally one or two teapots have cracks. If it's the kind of water seepage you're talking about, don't worry about it. Insist on making tea, and one day it won't seep.

Personal experience, no spraying, personal guess is that it has been a long time, and the tea mountain formed on the inner wall is naturally filled in that seam. Isn't it amazing?

It is risky to put some mud on it and put it back in the kiln. After all, you have tried water in this pot, and it may burn out if you don't do it.

Why does the teapot "crack"

When using teapot in winter, it is easy to burst, which is generally caused by the following reasons:

(1) The ambient temperature is too low.

In winter, the temperature of teapot itself is relatively low. If you use boiling hot water to make tea directly from the teapot, it is possible that the teapot will crack, which is also a "shocking" situation.

Purple clay pots may be better, and small red clay pots are particularly prone to cracking. In order to prevent this "shocking" situation, it is recommended to warm the pot in winter.

Spray the pot with 40-50 degrees water (the hot water in the water dispenser is about 5-60 degrees) quickly around the inside and outside of the pot until the pot is filled with warm water. Cover the pot, spray a shower of warm water on the pot cover, let the warm water preheat the pot, and then use this pot to make tea. Be careful not to let the boiling water continuously fix a certain point of the kettle, which is easy to cause problems when the ambient temperature is very low.

Another reminder, even if it is not winter, don't put hot water in the pot that has just been washed with cold tap water. Keep it at warm room temperature, let the pot warm first and then warm, and then make tea.

(2) The teapot itself has a "dark wound", and there are generally several kinds of "dark wounds":

A-The teapot was "broken" in the kiln, but it was not serious, with tiny cracks. However, such cracks are short and shallow, and there is no through crack. If you pay special attention to them or check them with a magnifying glass, you can see them clearly. If there is no particularly large "temperature difference", this pot will not leak.

B—— In the process of making teapot, at the joints of teapot: handle, bottom, spout and button, the producer used too little mud or scraped the mud thin at these joints with a needle, so these joints will be very fragile during the pot firing. If it is used improperly, it is easy to have problems.

C—— You did bump into the teapot in the process of using it, or bumped into it, but you didn't find anything wrong with it after careful inspection, or you didn't notice it at that time, but it also suffered "internal injuries". When you use it improperly and the contrast between the ambient temperature and the water temperature is too great, the already fragile pot will be "broken".

D—— In the process of using the teapot, it is sometimes knocked against the teapot, and a slight crack has appeared. However, due to the dark color of the teapot itself, the eyes can't find it at once. After using it for a long time, your tea scale enters these fine cracks, and these fine cracks appear clearly. You suddenly find out why my teapot is cracked.

In addition, if the pot is not used for a long time, the pot body will be excessively air-dried due to long-term exposure to the air, and the purple sand gap of the pot body will be completely dry, and the relative structural gap is also large, especially for the pottery pot with large particles. Because of the low iron content, the pot body structure will be looser, so pay special attention before using it again. The correct treatment method is to soak the pot in cold water for a period of time, so that the pot body is filled with water to support the skeleton of the pot body, increase the tension of the pot body, and then adapt the pot to the water temperature from low to high, so that the pot can be safely used.

How to repair the broken lid of the teapot?

If the price or commemorative significance of this pot is really high, it must be repaired!

You can take the teapot and teapot lid (broken) and find someone who can make the teapot lid, and re-burn the teapot lid with a small amount of purple mud! Or find someone who can make a teapot and repair it in various ways!

(Note: Don't fix it with any glue anyway! It's not worth it! )

Why does the teapot crack when it is used?

Teapots have three types of cracks:

I have encountered or touched the teapot during its use, but I didn't find any problems after careful inspection at that time, or you didn't pay attention at that time. As a result, the teapot suffered "internal injuries". When you use it improperly and the contrast between the ambient temperature and the water temperature is too great, the already fragile pot will be "broken".

The ambient temperature is too low.

For example, in winter in the northern cities of China, the temperature of the teapot itself is relatively low. If you use boiling hot water to make tea directly from the teapot, it is possible that the teapot will crack, which is also a "shocking" situation. In order to prevent this "shocking" situation, it is suggested that basin friends in the north develop the habit of ironing pots in winter. What is "scalding pot": pour a small amount of 80-degree boiling water into the pot, then shake the teapot, spray the pot with this water, and then make tea with this pot.

In the process of making a teapot, the joints of the teapot, such as the handle, the bottom, the spout and the button mouth, are very fragile because the producers use too little mud or the exposed needles scrape the mud very thin at these joints. If it is used improperly, it is easy to have problems.

Urgent! How to repair the damaged teapot?

There are four ways to repair the teapot: inlay, tin coating, solidification, gluing and cultural relic restoration.

First, inlay and tin plating.

From some traditional teapots in the Qing Dynasty and the Republic of China, it is not difficult to find that gold, silver, copper, iron, tin and jade have ever-changing magical functions on the residual teapots. If the mouth, body, handle and bottom of the teapot are slightly scratched, or even damaged, it can be repaired by inlaying or tinning. If it is repaired well, it will not only have no influence on the use of the teapot, but also have little influence on the aesthetics of the teapot, and even enhance the artistry of the teapot itself to a certain extent, showing a kind of incomplete beauty.

The decoration of the teapot itself is covered with gold, tin and copper.

Gold-inlaid edge: the gold-inlaid edge is inlaid on the edge of the spout, spout, bottom edge of the spout, periphery of the lid and buttons, which is magnificent.

Cladding tin: Cladding tin is a kind of jade pot with tin, which was invented by Zhu Jian. The periphery of the pot is wrapped in tin, and then poems and paintings are painted on the tin bag, and the spout, lid and handle of the pot are inlaid with jade. Elegant and unique, it is a distinctive decoration method, but unfortunately its technique was later lost, but tin is harmful to human body, so it is not recommended to make tea.

Copper-clad: Copper-clad means that the whole teapot body is wrapped with patterned copper pieces, such as bats, dragons and longevity. The edge of the spout and the periphery of the lid are also inlaid with copper sheets. Most of these decorative teapots are soft hanging beams. At this time, if these parts are damaged, using the above methods will not only have little effect on the overall effect of the teapot, but many repaired and modified teapot presents another luxury. If we can regain this skill, after some evolution and transformation, we can use it for the decoration of teapots. Maybe we can design and shape teapots with different flavors.

The cost of this repair method is relatively low, about 1000 yuan, which is more suitable for minor injuries of teapot. The repair effect shows the beauty of deformity and increases the artistry of teapot.

Second, curium [jū]

And "shovel pot", as a handicraft to repair teapot or residual pot, is not very common now. If there is a long crack in the teapot body, you can ask some professionals who specialize in repairing the teapot to repair it, but before that, you should keep the pieces of the teapot. We can't play with them often. Two pieces will touch porcelain. It doesn't matter if the teapot is covered with some porcelain. If it is a teapot, it will leak even if it is scraped. If the chipped teapot lacks porcelain, or the fragments are too small to punch holes in it, it should be fixed with wax to prevent leakage. If your love pot is accidentally broken, don't throw it away. Every piece must be found, and the shovel will be glued with wax.

The pot is cracked, so it's best to shovel it at the cracked place to avoid the stress crack from spreading. The lid of the pot is broken, and there is no shovel. You can stick it with wax, which will not affect the shovel again. If the teapot is not short of porcelain, it will not be fixed with wax when shoveling. Shovels come in many sizes. The "rice shovel" is as big as a meter and shaped like a meter. The "willow shovel" is longer than the "rice shovel" and the two ends of the shovel are slightly narrower. The "diamond shovel" is the largest and is generally used for large porcelain. This spade teapot is exquisite. Generally 1 cm has three shovel nails, which is the most suitable. Shovel nails should be made according to the crack shape of teapot. The smallest copper nail is only 2 mm, and the size, arrangement and depth of the shovel nail are strictly exquisite. There are 3 ~ 4 kinds of shovel nails in general shovel workers.

The teapot is made of clay and fragile. After breaking, the shape is different, and the knife-edge oblique fork often breaks. In order to prevent the thinnest part of the teapot wall from breaking, it is necessary to increase the length of the chisel nail. When restoring antiques or other valuable porcelain, you can't drill through holes. You have to drill two points and leave one point. Looking at the porcelain that has been drilled, we can see that the drilled eyes are light-permeable, but airtight. The remaining point is to ensure that the copper nail for shoveling porcelain does not penetrate the porcelain. This is the rule of shovel. The hole drilled is bigger than the mask, so when the copper nail is tapped on the porcelain piece, the nail head in the eye is swollen and permanently fixed on the porcelain piece.

After the teapot is made, it should be leveled with iron powder or lime (gypsum or putty) to increase the firmness of the shovel nail, plug some gaps lacking porcelain and prevent water leakage. However, as long as there is no shortage of porcelain in the teapot, there is no need to plaster it. After all, iron powder and lime (gypsum or putty) affect the overall beauty of the teapot. There is a little water leakage or seepage in the teapot ... >>

Under what circumstances will the teapot crack and burst?

Making tea with boiling water will not crack the teapot, but if the temperature difference is large, such as making tea with boiling water at very cold room temperature at once, the teapot will burst when it is cold and hot, so it is necessary to heat the teapot in advance to avoid this situation.
