A technology of making black pottery urn

Abstract

The invention discloses a process for manufacturing a black pottery cinerary casket. The process is characterized by including the following steps: A. carefully selecting sedimentary soil on an ancient riverbed of the Yellow river as a raw material; B. utilizing a ball mill to levigate the raw material and filtering the levigated raw material through a 70-mesh screen; C. dosing; D. vacuum pugging; E. throwing; F; conducting mud board pressing; G. mould blank printing; H. sealing gaps; I. reshaping; J. press polishing; K. carving; L. conducting bonding connection; M. twisting polishing; N. drying in the shade; and O. burning. The process solves the problem that a product is contracted and deformed in the manufacturing process and is broken in the burning process.

Description

technical field [0001] The invention relates to a process for making a black pottery urn. Background technique [0002] In the face of urns of different materials on the market, pottery is the only urn.
