Problems solved by technology

[0006] However, the density of black pottery is low, the air permeability is too large, too permeable, and as the saying goes, it is too "thick", which makes it basically lose its use value and collection value.

Embodiment 1

[0012] A method of firing black green pottery. The material is old soil that has been deposited for thousands of years at the foot of Shennong Mountain. The old soil contains a large proportion of iron, good viscosity, and rich trace elements; The material is fired into black pottery and taken out of the firewood kiln; then it is put into the gas kiln for the second stage of firing. In the gas kiln, the temperature is first raised to 900°C, and then the temperature is raised little by little through the method of raising the temperature up and down. First raise the temperature by 10°C for half an hour, lower it by 5°C and keep it for half an hour, then raise the temperature by 10°C for half an hour, then lower it by 5°C and keep it for half an hour, then raise the temperature again, and cycle in turn until it reaches 1200°C, then turn off the gas source , when the temperature drops below 100°C, the kiln is started, and then the temperature is lowered to below 50°C to exit the k...

Embodiment 3

[0016] A method of firing black green pottery. The material is old soil that has been deposited for thousands of years at the foot of Shennong Mountain. The old soil contains a large proportion of iron, good viscosity, and rich trace elements; The material is fired into black pottery and taken out of the firewood kiln; then it is put into the gas kiln for the second stage of firing. In the gas kiln, the temperature is first raised to 900°C, and then the temperature is raised little by little through the method of raising the temperature up and down. First raise the temperature by 10°C for 40 minutes, then lower the temperature by 5°C for 40 minutes, then raise the temperature by 10°C for 40 minutes, then lower the temperature by 5°C for 40 minutes, then raise the temperature again, and cycle in turn until it reaches 1200°C, turn off the air source, and wait until the temperature drops The kiln is opened below 100°C, and then the kiln is lowered to below 50°C to obtain black gre...

Abstract

The invention relates to a firing method of black pottery. The method is as below: selecting old soil precipitated at the foot of Shennong Mountain for millennium as a material; firing the soil into black pottery according to the traditional black pottery technology, and taking the black pottery out of a firewood kiln; and then putting the black pottery into a gas kiln for a second stage of firing; first rising the temperature in the gas kiln to 900 DEG C; then slowly rising the temperature through a high-up and low-down heating method, first rising 10 DEG C and maintaining 20-40 min, then reducing 5 DEG C and maintaining 20-40 min, rising 10 DEG C again and maintaining 20-40 min, and then reducing 5 DEG C, maintaining 20-40 min and rising the temperature again; circulating the process until firing to 1200 DEG C; turning off the gas; opening the kiln until the temperature drops to below 100 DEG C; and then drawing until the temperature drops to below 50 DEG C, so as to obtain the black pottery. The invention has the beneficial effect that the method solves the defect of too rough black pottery, the fired black pottery has higher density, harder texture, unique kiln change, higher artistic value, and better collection property.

Description

technical field [0001] The invention relates to the technical field of pottery firing, in particular to a firing method of black green pottery. Background technique [0002] Thousands of years have passed, and there is a kind of life that, in the long multiplication of washing away the lead, gave birth to a cultural treasure in the soil of the land of China-black pottery. Generations of craftsmen have worked tirelessly for this and passed it down from generation to generation. [0003] The development of pottery culture is writing a glorious chapter of Chinese history and civilization. Qinyang City, located in the birthplace of Chinese historical civilization, was historically known as the Yiqi feudal territory, the former land of Shangji, and the famous state of Heshuo. It is now a famous historical and cultural city in Henan Province, and a "Millennium Ancient County" recognized by the Geography Department of the United Nations Educational, Scientific and Cultural Organiz...
