Abstract:This paper illustrates the inventory analysis of the household ceramic output and input in different decorating processes, and the environmental impact potential at each stage of their life cycle is calculated and explained. The results show: the environmental impact of overglaze, inglaze, and underglaze decoration is 0.287, 0.259 and 0.229, respectively.LCA of household porcelain production is an effective tool for quantitatively evaluating the ecological design of a product.
