Problems solved by technology

Some "medicine pots" and "medicine bowls" have gradually become problems that endanger people's life safety. Many colorful glazes in daily-use porcelain contain a large amount of heavy metals, which cannot meet food-grade standards.
Patent 2013101794973 discloses a preparation method of colorful mother liquor Tianmu porcelain and its products, breaking through the bottleneck of only preparing yellow-red veins, black bottom glaze, and gray-brown wood-leaf Tianmu porcelain at that time, and providing a method for using natural minerals The method of preparing colorful mother liquor Tianmu porcelain with chemical raw materials. The preparation raw materials of this technology glaze contain chemical raw materials, and there is no detailed research on whether there are heavy metals left. If harmful substances are precipitated during use of daily ceramics, it will endanger human health.

Abstract

The invention relates to the technical field of ceramic composite materials, in particular to a preparation method of ceramic glaze based on leaves. The preparation method of the ceramic glaze based on leaves includes: subjecting pug with high iron content to low temperature biscuit firing, then spraying wood-leaf glaze of certain thickness and conducting high temperature firing. The preparation method of the ceramic glaze based on leaves provided by the invention replaces the traditional preparation methods of leaf-shaped glaze, has the characteristics of simple operation, stable and reliablefiring conditions, strong operability, and more diverse selectivity of the ground glaze color. The glaze prepared by the method provided by the invention has metal texture and no heavy metal toxicity, can reach the edible grade standard, has obviously improved color stability and high finished product rate, and can be used in celadon decoration and domestic ceramic decoration or painting field.

Description

technical field [0001] The invention relates to the technical field of ceramic composite materials, in particular to a preparation method of leaf-based ceramic glaze. Background technique [0002] The production of Konoha is completely the crystallization of nature and the wisdom of the ancients. It has a firing history of more than 1,200 years, and black glazed porcelain is the most representative at that time. Konoha cups are fired by attaching natural leaves to utensils. Usually, one leaf is attached to the center of the cup, and some are attached to the wall and mouth of the cup, or two leaves overlap. This almost natural decoration, with clear and vivid veins of wood leaves, has extremely high artistic value and economic value. Based on this, people prepared a strong alkaline solution to treat the leaves. At first, this method could only be applied to Jizhou kiln porcelain with a dark body surface. After being made into porcelain, the leaves are golden in color. Due ...
