Abstract

In the invention, shale clay of Changbai mountain and low-temp, clay are uniform mixed, then are processed by ball-milling, seasoning, mud treating, base stretching, polishing, carving and firing. The carving technology includes ornamental engraving, relief sculpturing, line engraving and shadow engraving. In firing process, wood is used as fuel, reduction flame firing principle is used to make iron oxide in pottery clay is reducted to generate black ferrous oxide by charcoal in high temp, 1000-1100 deg,C, for 24 hours, that is the reason that black pottery handicraft article is black on whole body.

Description

Black pottery handicraft and preparation method thereof

Technical Field

The invention relates to the technical field of black pottery production, in particular to a black pottery handicraft and a preparation method thereof.

Background

The domestic black pottery artware is mainly produced by Shandong Longshan and Hebei Librarian pottery, because the Shandong Longshan and the Hebei Librarian pottery are both in the yellow river basin, and the main raw material for producing the black pottery is yellow river sludge, which is formed by low-temperature sintering, and the quality and the technological level of the black pottery artware in the current unearthed cultural relic period can not be achieved.

Disclosure of Invention

The black pottery artware is prepared by sintering yellow river sludge serving as a main raw material at low temperature, and the quality and the technological level of the black pottery artware in the current unearthed cultural relic period can not be achieved. The invention provides a black pottery handicraft and a preparation method thereof, wherein the black pottery handicraft and the preparation method not only can utilize shale soil and low-temperature clay of Changbai mountain to produce the black pottery handicraft, but also can produce the black pottery handicraft without post-treatment through high-temperature carburization, and the quality of theblack pottery handicraft can reach the quality and the process level of the black pottery handicraft in the period of unearthed cultural relics at present.

The technical scheme adopted by the invention for solving the technical problems is as follows: the black pottery handicraft is produced with Changbai mountain shale and low temperature clay as main material and through mixing, ball milling, ageing, pugging, drawing, polishing, carving with hollowed-out part, relief, line carving and shadow carvingThe method is characterized in that wood is used as fuel, a reduction flame burning principle is adopted, the temperature in a kiln is 1000-: the black pottery handicraft is the cause of black whole body, and the black pottery handicraft is taken out from the kiln, polished, colored, inspected to be qualified and delivered from the factory.

Detailed description of the preferred embodiments

Example (b): the black pottery handicraft is produced with Changbai mountain shale and low temperature clay as main material and through mixing, ball milling, ageing, pugging, drawing, grinding, carving to form hollowed part, relief, line carving and shadow carving, and through burning wood as fuel, reducing flame burning at 1000 deg.c inside kiln to reduce iron oxide in pottery clay at high temperature with charcoal to produce black ferrous oxide for 24 hr.

Claims (2)

1. A black pottery handicraft is characterized in that: is prepared from shale and low-temp clay as main raw materials.

2. A black pottery handicraft and its preparation method as claimed in claim 1, wherein: the burning process is that wood is used as fuel, the reduction flame burning principle is adopted, the temperature in a kiln is 1000-1100 ℃, so that iron oxide in pottery clay is reduced by charcoal at high temperature to generate black ferrous oxide, the time is 24 hours, and the chemical formula is as follows: namely the cause of the black whole body of the black pottery handicraft.
