Problems solved by technology

[0003] The main types of Jianzhan are Rabbit Haozhan and Oil Dropping Cup. The current reported methods for preparing Jianzhan have the following limitations: first, the choice of formula and temperature control are not clear, and the yield of good products is low; second, Jianzhan glaze Ordinary surface color, low innovation
In order to protect forest resources, the government restricts the use of firewood-fired dragon kilns, and it is difficult to control the temperature of firewood-fired dragon kilns, and the yield is low (about 10-30%)
The temperature control of the electric kiln is relatively accurate, but the temperature uniformity is poor. At the same time, a reducing atmosphere cannot be formed in the kiln, and it is necessary to artificially add oil and diesel to create a reducing atmosphere. , Diesel fuel injection technology is extremely difficult to master, the finished product rate is about 30-60%, and the firing time is long

Embodiment 1

[0038] The firing process of luminous Jianzhan includes the following steps:

[0039] (1) prepare body raw materials and glaze slurry;

[0040] The green body raw material is prepared by the following method: mixing 4 parts by weight of loess and 6 parts by weight of kaolin, pulverizing, elutriating, passing through a 60-mesh sieve, press filtration, mud refining, and aging to obtain the green body raw material;

[0041] Described glaze slip is prepared by following method:

[0042] Mix the glaze stone of 3 parts by weight, the Longquan stone of 3 parts by weight, the fluorite of 2 parts by weight, the potassium feldspar of 0.5 parts by weight, the plant ash of 0.5 parts by weight, the limestone of 0.5 parts by weight, the iron oxide of 0.5 parts by weight, Pulverize, pass through a 100-mesh sieve, add water to adjust to a glaze slurry with a concentration of 50°Bé;

[0043] The preparation method of the plant ash is as follows: take 20 parts by weight of pine wood and 1 par...

Embodiment 2 and Embodiment 3

[0062] Jianzhan is very sensitive to the parameters of the preparation process, and a small change in the process parameters will have a great adverse effect on the appearance and other characteristics of the final product of the Jianzhan, and even lead to the failure of the preparation of the Jianzhan. Therefore, the requirements for the preparation process of Jianzhan are very strict. . Example 2 and Example 3 prepared luminous building lamps according to the same preparation process as in Example 1. The properties of the luminous building lamps prepared in Example 2 and Example 3 were basically similar to those of the luminous building lamps prepared in Example 1. The results showed that, The glow-in-the-dark lamp prepared by the preparation process of Example 1 has a high yield, and the method has good repeatability, strong stability, and is easy for large-scale production.

[0063] In the process of preparing the luminous building lamp, the inventor has gone through a lot...

Abstract

The invention discloses a firing process of a noctilucent Jianzhan cup, and the method comprises the following steps: preparing a green body raw material and glaze slip, drawing and molding the greenbody raw material, and trimming to obtain a green body; glazing; and putting the glazed green body into a liquefied gas kiln for roasting. The noctilucent Jianzhan cup fired by the method is fine andsmooth in texture, smooth and flat, almost free of needle holes, greenish in glaze color grey, greenish in green, uniform, clean and elegant in glaze surface, has ice cracks and is full of jade feeling. The noctilucent Jianzhan cup is weak in light emitting day and strong in light emitting night, emits green light and glittering light in a dark environment, and has extremely high artistic value and appreciation value.

Description

technical field [0001] The invention relates to the technical field of porcelain, in particular to the firing process of luminous built-in lamps. Background technique [0002] Jianzhan, because it was produced in Jian'an County, Jianzhou Prefecture, Song Dynasty, is called Jianzhan. It flourished in the late Northern Song Dynasty and the early and middle Southern Song Dynasty, and was used by the royal family in the Song Dynasty. [0003] The main types of Jianzhan are Rabbit Haozhan and Oil Dropping Cup. The current reported methods for preparing Jianzhan have the following limitations: first, the choice of formula and temperature control are not clear, and the yield of good products is low; second, Jianzhan glaze The color of the surface is ordinary, and the innovation is low. [0004] At present, firewood-fired dragon kilns and electric kilns are mainly used for firing Jianzhan. In order to protect forest resources, the government restricts the use of firewood-fired dra...
