AI Technical Summary
Technical Problem
Existing wood-fired ceramics are prone to glaze loss due to firing failures, resulting in high breakage rates, low economic benefits, and negative environmental impacts.
Method used
By polishing the unglazed ceramic body, applying raw lacquer and baking it, and then processing it with lacquer techniques, including eggshell lacquer and rhinoceros hide lacquer, the adhesion of the lacquer surface is enhanced, thus forming a finished lacquer ceramic product.
Benefits of technology
It reduces the waste rate of deglazed ceramics, improves economic efficiency, achieves environmental protection, avoids paint peeling problems, and improves product reliability.

Abstract
本发明提供一种基于脱釉陶瓷胎体的大漆陶瓷制备方法，包括如下步骤：选取胎体烧制成陶瓷时落灰变化中存在表面脱釉的陶瓷作为再加工陶瓷，表面脱釉满足预设指标；将再加工陶瓷的脱釉部分进行打磨至0.2‑0.5mm之间的深度；在打磨后的区域的表面刷一层生漆，并进行烤制，烤制温度为160‑180℃，烤制时间为45‑60分钟；将再加工陶瓷表面完成烤制生漆后的区域进行大漆工艺制作，得到大漆陶瓷成品。与相关技术相比，本发明的基于脱釉陶瓷胎体的大漆陶瓷制备方法能将烧制失败导致脱釉的废弃陶瓷再利用，降低了生产成本且环保效果好。
