Technical Field

The invention belongs to the technical field of painted pottery processing, and particularly relates to a production process method of low-relief painted pottery.

Background

The first-class painted pottery inherits the three-color wind of Tang in the period of Liu Tang, and the glaze color of the first-class painted pottery is yellow, brown and green. In the period from late period to the republic of China, the world first colored pottery is influenced by the opera art at that time on the basis of inheriting the pottery preparation skill at the early period, and the ornamentation content is more colorful, so that besides flowers, birds, fishes and insects, a large number of opera figure ornamentations taking the traditional drama as the subject appear. The first decoration technique of colored pottery is mainly divided into scratching, ruling, colored drawing and die printing and plastic pasting. The colorful decorative effect of the first colored pottery accords with the popular aesthetic sense of people. Besides carving and marking, the first-boundary painted pottery has a common technique of plastic pasting. The shallow relief is a relief technique corresponding to the high relief, the carved patterns and patterns protrude shallowly from the bottom surface, the technique is popular in the late Qing Dynasty, is especially common in the aspects of lettering and the like, and belongs to the technical field of sculptures and painting in the past, the object is processed by a compression method, a three-dimensional space is represented by perspective and the like, and the three-dimensional space is only viewed from one side or two sides. Embossments are generally attached to another plane and are therefore used mainly in construction and stone carving. For example, a method of carving a stone surface with a bas-relief. The contrast sense of the bas-relief is not very strong, the pattern structure is not very different from the background, like the statue of the palm cloud and water of the Bajon temple in Wu Grottoes of Cambodia, the bas-relief carving technique is mainly characterized in that the object image is in an arc-shaped bulge, and the detail of the bulge object image is still carved by the shade line. This technique is most commonly used on stone and relief jade across the country. Such as national second-level cultural relics bas relief musicians drum beating jade belt decorations and the like. The method for producing concave-convex relief on ceramic glaze surface and used stained paper paint thereof in Chinese patent CN031142044 adopts stained paper or water-absorbing paper, etc., actually the process method is known as ceramic decal paper process, the ceramic decal paper is mainly used for decoration of ceramic ink color, the stained paper only bears the ink, then the ink is transferred to the transfer medium on the ceramic blank, actually, the relief effect is difficult to achieve, and similar methods all use high-temperature decomposed organic matter, the process is complex and difficult to achieve, the application effect is not good, and the method is not suitable for production of colored ceramics. Unfortunately, painted pottery is difficult to emboss, stress is concentrated and damaged, and therefore, the market cannot see the real low-relief painted pottery product. With the rapid development of modern industrial products, the first-world painted pottery produced by the traditional technology is also manufactured by hands, the technical content is high, the manufacturing process is complex, the cost is high, the economic benefit is low, and the mass production is difficult to realize. As the handicraft, the first painted pottery is limited by the technology, and those skilled in the art are in urgent need to develop a production process method of low-relief painted pottery.
