Technical steps of ceramic restoration: technical strategies of ceramic restoration
First, the technical steps of ceramic repair
1. Take the original for archiving. Next is the cleaning work. Put the appliance into an ultrasonic cleaning machine, and put a proper amount of chemical reagent acetone into water for slight heat to remove stains and adhesives. After starting for 2 to 3 hours, the dirt glue naturally falls off. During the cleaning process, you should check whether there are fragments of ancient porcelain in the sediment of the washing machine. If it should be cleaned, make sure it is consistent with the equipment, and then use these parts to make the original taste as much as possible. True face; Firstly, without using an ultrasonic cleaner, the black in the punch is cleaned, chlorine-containing disinfectant is dripped on the punch, and a blower is aimed at the punch to accelerate the evaporation of drugs. Usually, this procedure must be repeated several times to completely wash off the black gas in the pipeline and then rinse it with water. Sometimes it is difficult to clean up because of the darkness, and it only takes a few days to clean up this step.
2. Make repairs. Generally, colorless and transparent ancient porcelain pieces are bonded with 502 glue or two-component epoxy resin. Porcelain powder and synthetic material (polyester) are used as porcelain putty to make the bottom flat and fill the gap. After the ancient porcelain is assembled, the background color, blue and white color and glaze color will be used. Glaze is a new kind of imitation glaze coating, such as polyester. After the glaze is finished, the surface of the object is bright, high in hardness and decorative. Sometimes along the blue-and-white line of the mouth, it is deep in the middle and shallow on both sides, just like the ink of Chinese painting, looming, virtual and real. He said that when processing the edge of the mouth, the process of manual wire drawing and mechanical spraying should be combined to achieve seamless connection. Finally, use floor wax to shade the light. The restored ancient porcelain, as always, shines brightly and reappears its original appearance.
Second, the ceramic repair background technology
1. Pottery made of clay is called pottery, and pottery made of pottery is called porcelain. Ceramics is a general term for pottery, pottery and porcelain. The ancients called ceramics cockroaches. Any clay made of clay and porcelain clay can be used as raw material. After compounding, molding, drying and baking, it can be called ceramics. Ceramic restoration technology is a special artistic creation that integrates modeling, sculpture, color, calligraphy, painting and chemical industry. The restoration of ancient ceramics must be carefully made, seemingly simple blue and white lines. In the process of restoration, it is still necessary to "shine". The whole restoration process includes disassembly, cleaning, filling, grinding, priming and upper part. Color, glass, indentation and many other steps.
2. Ceramics are easily broken due to its fragile texture. Therefore, the repair method of ceramics is very harsh. The ceramic repaired by traditional ceramics has a small gap and may crack again.
Third, daily ceramic maintenance methods
1. Strong ultraviolet rays can easily cause the ceramic surface to change color and the glaze layer to fall off. Therefore, it is necessary to prevent and reduce the glare on pottery. Collection room's windows are hung with opaque curtains or stained glass.
2. If the temperature in collection room is unstable or the temperature difference is too large, it will damage the pottery. The indoor temperature should be kept at 17-25℃, the humidity should be 50%-60%, and the relative humidity should not exceed 5%-6%. It is too dry and the humidity is not conducive to pottery collection.
3. Too much dust can easily cause some damage to pottery. When the surface of the object fades, brush off the pottery regularly and store it in the cupboard or shelf.
4. Pottery is easily broken, and ears, parts, mouth and other parts are easily broken. Therefore, it is not appropriate to directly touch and squeeze these fragile parts. You should handle pottery with care. Avoid collision or friction.
The above is the introduction of the ceramic repair technology we brought.
