Artware of basalt and preparation method

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

technical field [0001] The invention relates to the technical field of black pottery production, in particular to black pottery crafts and a preparation method.
