Description

Technical Field

[0001] The invention belongs to the technical field of handicrafts, and in particular relates to a high-temperature ceramic xun and a preparation method thereof. Background Art

[0002] The pottery xun is an ancient closed-mouth wind instrument. It is usually made of a fixed ratio of kaolin, clay, feldspar, quartz stone and other raw materials, and is sintered at a medium temperature of 800-1200℃ and undergoes a series of processes. It is pear-shaped or oval, pointed at the top and wide at the bottom, with a flat bottom and hollow, and has six holes. Now there are also eight-hole, nine-hole, ten-hole, and double-octave ones. The sound is rough and long, exuding a unique musical charm.

[0003] With the change of the times, the production and playing skills of the pottery xun were once in danger of being lost. However, in recent years, as people pay more attention to traditional culture and increase their awareness of protecting it, the production and playing skills of the pottery xun have been inherited and developed to a certain extent. At the same time, the pottery xun has gradually attracted more attention and love, and has become a musical instrument with unique charm. However, the existing methods for preparing the pottery xun have the following problems:

[0004] 1. The design and size of the existing pottery xun's mouthpiece are not conducive to the elderly's getting started, and it is relatively complicated to use;

[0005] 2. The existing ceramic xun is prepared by sintering at a medium temperature of about 800-1200℃, which has average porcelain properties and low strength;

[0006] 3. The existing pottery xun has a low strength, so the wall thickness is designed to be thicker in order to make up for the lack of low strength, which makes the appearance more clumsy and difficult to carry;

[0007] 4. Existing pottery ocarinas are not resistant to dirt and tend to change color over time.

[0008] Therefore, in order to solve the above problems, a high temperature ceramic xiao and a preparation method thereof are proposed. Summary of the invention
