Embodiment 1

[0025] The present invention provides a technical solution: a method for increasing the kiln variability of Nixing pottery large-scale vessels, comprising the following steps:

[0026] (1) prepare east mud: place the white mud on the east bank of the Qinjiang River in a closed place for shelter from rain, and naturally air-dry and weathering, the weathering treatment time is 120 days, and then the crushed soil is processed for subsequent use;

[0027] (2) Preparation of western mud: place the red mud from the west bank of the Qinjiang River in the open air, and experience sunshine and rain to make it fragmented, dissolved, oxidized, and reach a weathered state. The weathering treatment time is 180 days, and then the soil is crushed. for standby;

[0028] (3) Preparation of mud: mix the processed east mud in step (1) and the treated western mud in step (2) in a ratio of 4:6, mix 100 parts by weight of soil, add 10 parts by weight of iron red powder , the particle size of the i...

Abstract

The invention discloses a method for increasing the furnace transmutation rate of a Nixing pottery large vessel. The method comprises the following steps: preparing east clay; preparing western mud; preparing blank mud; forming a green body; drying the green body; firing the green body; and grinding and polishing the fired body. According to the method for increasing the kiln transmutation rate of the Nixing pottery large vessel, a proper amount of metal oxide is added into a traditional pottery blank; under the action of a reduction flame atmosphere, the surface of the Nixing pottery is influenced by pine branch oil smoke and the like, color variation is generated, and furnace transmutation occurs; the content of the metal oxide in the blank is directly increased when the blank is manufactured, so that the quantity of the metal oxide participating in the reduction reaction in the firing of the green body is increased; therefore, the probability of color variation is further improved, and the kiln transmutation rate of the Nixing pottery is improved; after different metal oxides are reduced, the Nixing pottery subjected to kiln change shows different colors or lines, and the variety of kiln change of the Nixing pottery is increased by adjusting the metal oxidation variety, so that the commercial value of the Nixing pottery is improved.

Description

technical field [0001] The invention relates to the technical field of pottery preparation, in particular to a method for increasing the kiln variability of large Nixing pottery vessels. Background technique [0002] Nixing pottery is a special product of Qinzhou City, Guangxi Zhuang Autonomous Region. It is a product of China's national geographical indication. The pottery blanks are made of soft clay in the east and bones in the west. The bones and flesh can support each other and are fired by Nixing pottery firing techniques to form Nixing pottery. Nixing pottery vessels are divided into large vessels (height ≥ 35cm) and small vessels (both height <35cm), Dongni is soft clay with a yellowish-white color and contains a small amount of quartz sand; Xini is a purple mudstone with high iron content, purple in color and surface There is a small amount of iron impregnated in the layer, which is hard clay. Kiln transformation is the change of color and texture caused by a se...
