Description
Technical Field
The invention belongs to the technical field of cultural relic protection, and particularly relates to a method for removing sludge on the surface of a wet colored drawing pottery after ancient examination.
Background
In the civilization history of Chinese nationalities, the appearance of painted pottery pushes the decoration process of pottery making to a brand new height, and the painted pottery becomes a wonderful flower in the civilization history of China. Painted pottery is different from painted pottery in the age of new stone ware and glazed pottery, and various colors are painted on the fired pottery. The colored drawing of the archaeological unearthed colored drawing pottery is prepared by blending animal or vegetable glue and mineral pigment and then directly drawing on the surface of the fired pottery. Because the colored drawing pottery is buried underground for a long time and is influenced by various environmental factors, the natural cement in the colored drawing pigment is aged and loses the effect, the colored drawing layer becomes very fragile, and the whole or local falling of the colored drawing layer is easy to occur in the cleaning process. Meanwhile, the sludge and the colored drawing layer are difficult to separate due to the mutual permeation of the colored drawing layer and the sludge layer, and the sludge layer is usually stripped together with the colored drawing layer when the sludge layer is dried, so that great danger is formed for colored drawing preservation of colored drawing pottery, and the artistic value and the research value of the colored drawing pottery are greatly influenced. Therefore, it is important to select a method to peel the sludge layer from the colored drawing layer as soon as possible after the colored drawing is unearthed.
At present, the clay on the surface of the painted pottery is cleaned mainly by a mechanical method, or the wet painted pottery covered with a mud layer is integrally pre-reinforced and then the clay on the surface is removed by the mechanical method, the method mainly has the problems that the mud layer and the painted pottery can be simultaneously reinforced, the difficulty is still large when the clay is separately removed, and the mud layer and the painted pottery can still be peeled off together if the clay is careless; for dry colored drawing pottery, the method adopted is to drip alcohol solution on the mud layer covering position for local loosening of soil, and then mechanically remove the soil, and the method is required to ensure that the bonding degree of the colored drawing layer and the pottery body is better.
Disclosure of Invention
The invention aims to overcome the defects and provide a method which can effectively remove the sludge on the surface of the wet colored drawing pottery from the ancient ruined soil, has small damage effect on a colored drawing layer and can furthest reserve the fragile cultural relic colored drawing.
Aiming at the purposes, the technical scheme adopted by the invention is as follows: uniformly stirring water-based epoxy emulsion with solid content of 10-25% and distilled water according to the volume ratio of 1: 4-1: 2 at room temperature to prepare a film-forming material; the film forming material is evenly sprayed on the surface of the wet colored drawing pottery with the silt layer on the surface in a fog shape, the wet colored drawing pottery is naturally dried in a room temperature environment, and after the film layer and the silt layer are raised, the film layer and the silt layer are taken down together in a lifting way, so that the surface of the colored drawing pottery is cleaned.
In the method, the water-based epoxy emulsion with the solid content of 18-20% and distilled water are preferably uniformly stirred at room temperature according to the volume ratio of 1: 3-3: 7 to prepare the film-forming material.
The pH value of the water-based epoxy emulsion is 6-8, and the prepared film forming material can form a film when being sprayed on the surface of a wet mud layer for 24 hours at room temperature.
In the above method, the thickness of the sludge layer is preferably < 2 mm.
The invention has the following beneficial effects:
1. the invention uses the water-based epoxy emulsion as the film forming material, and because the water-based epoxy emulsion is water-based emulsion and does not repel a moist sludge layer, the permeability on the surface of moist and sludge painted pottery is very low, and the epoxy mainly forms a film on the surface of the sludge. After the epoxy resin is sprayed on the surface of the sludge layer, a small part of the epoxy resin gradually permeates into the sludge layer, but most of the epoxy resin particles cannot permeate into the sludge layer, the epoxy resin is only dried on the surface to form a film, and the film layer and the sludge layer are well combined. In the historical relic lasts the drying process, rete, soil layer, colored drawing layer humidity are different, lead to the stress difference for the rete rises to stick up the chap, and rete and mud layer separate with the colored drawing layer together, and at this moment, through simple physical method, take off the rete of checking up and mud layer together and just can expose bottom colored drawing layer, and the destructive action to the colored drawing is minimum.
2. The method adopts an auxiliary film forming method and borrows stress difference to remove the sludge layer, can furthest reserve the original appearance of the bottom colored drawing, has better effect on reserving the cultural relic colored drawing layer, greatly improves the treatment effect of the archaeological unearthed colored drawing pottery cultural relics, has simpler selected materials and methods, accords with the field treatment principle, and also accords with the minimum intervention principle of the cultural relics.
