Abstract

The invention relates to a firing method for high-temperature firing bone daily-use porcelain, which belongs to the technical field of ceramic products. The parts by weight of the mud and glaze formula components are: mud: 70-80 parts of talc, 3-4 parts of bone charcoal powder, 3-6 parts of feldspar, 4-7 parts of bentonite, 9-13 parts of Datong soil, Sodium humate 0.2-0.5 parts; glaze: potassium feldspar 55-62 parts, quartz 9-12 parts, longyan soil 9-11 parts, lepidolite 3-4 parts, zinc oxide 3-5 parts, waste porcelain powder 9‑10 parts and 2‑3 parts of bone charcoal powder are prepared by mud and glaze, shaped, dried, glazed, and fired at high temperature. The firing time is 8‑12 hours, and the maximum firing temperature is 1280‑1320 °C. The novel bone daily-use porcelain fired by the invention has good transparency, strength and whiteness, is bright and clean, and has high ornamental value, so it has broad application prospects.

Description

technical field [0001] The invention relates to a firing method for firing bone daily-use porcelain at high temperature, and belongs to the technical field of ceramic products.
