Crystal glass light transmission porcelain painting and production process thereof

Abstract

The invention discloses a crystal glass light transmission porcelain painting. According to the porcelain painting, transparent glass serves as a substrate, the softening point temperature of the transparent glass is not lower than 700 DEG C, low-temperature ground glazes are sprayed to the surfaces of the transparent glass, the firing temperature of the ground glazes is 800 DEG C or less, the ground glazes serve as bonding layers, the surfaces of the ground glazes are coated and printed, the coated and printed transparent glass is fired in a kiln at the temperature of 800 DEG C or less once to prepare the porcelain painting, and the ground glazes contain sodium bicarbonate or sodium carbonate which accounts for 1 / 4-1 / 3 of the total weight of the ground glazes. According to the porcelain painting, low-temperature glazes and glass with high softening point are selected, contradictions between glaze forming and glass softening are solved, a lot of sodium salt is added into the ground glazes sprayed to the surfaces of the transparent glass, and the sodium salt and the glass can react at the high temperature to form the bonding layers, so that the glazes can be firmly combined on the surfaces of the glass.

Description

technical field [0001] The invention relates to the technical field of porcelain paintings, in particular to a crystal glass light-transmitting porcelain painting and a manufacturing process thereof. Background technique [0002] Traditional porcelain painting is a kind of flat ceramic handicraft made by using special chemical pigments on plain porcelain plates, hand-painting, glazing, and firing at high temperature. Porcelain paintings can be mounted or embedded in screens for ornamental purposes. Porcelain paintings can be traced back to the Qin and Han Dynasties, while porcelain paintings in the true sense appeared in the middle of the Ming Dynasty. From the mid-Qing Dynasty, the development of porcelain painting has become prosperous. In the existing porcelain paintings, except for the artistic value of the paintings, their structural forms are the same. They are all painted on thick white porcelain plates, painted, glazed, and then fired at high temperature once and t...

AI Technical Summary

Problems solved by technology

But there are many problems with this idea: 1) Since the glass is amorphous, it starts to soften when it reaches a critical temperature, so it cannot be fired at high temperature, but the glaze on the glass surface needs to be fired at high temperature; 2) The surface of the glass is smooth and easy to spray. After the glaze on the glass surface is molded at high temperature, it cannot be completely combined with the glass. Usually, in the finished product, either the glass has already softened and deformed, or the glaze layer on the glass surface has already separated from the glass surface and is self-contained.
