This time, I recommend you the works of Zhang Ronggui and Zhang Changshuo, "The Origin of the Mechanism of Obscuration and Glaze", which is jointly published by Huiwen Lian and Shandong Qilu Audio and Video Publishing Co., Ltd.
The purpose of "The Origin of the Mechanism of The Glaze of the Jianzhan" is to analyze the corresponding links in the firing process of the Jianzhan, the multi-path of the body composition, the mineral glaze composition, the temperature control and then the addition of auxiliary materials, the opening and closing of the temperature, etc., to comprehensively sort out and explain the excellent Yaochang in the jianzhan in theory, and through these interpretations, hope to make up for the overcoming of the doubts and difficulties of others in the firing process of the jianzhan, in order to achieve the purpose of explaining the doubts and doubts of the reader.
This work is not only for a wide range of Jianzhan collection readers, but also for Jianzhan firing craftsmen to accurately grasp the change of Jianzhan firing content. For some readers, especially the practitioners of Jianzhan firing, this work is a tool work that can be used for reference, the process introduction is clear, the operation has rules to follow, and try to give the reader a clear explanation, so that the reader can operate and get started after reading, in order to become a high-end theoretical guidance work of Jianzhan firing.
The author Zhang Ronggui, pen name Qinghe resident, contemporary calligraphy and painting, literary and historical scholar. In 1981, he contacted Jianzhan, and after 2000, he excavated the history and field investigation and excavation of Jianzhan and began to burn Jianzhan in 2002, which is one of the early practitioners of Jianzhan in theory and practice, and has authored monographs such as "Exploration of the Correlation between Jianzhan Glaze Color and Firing". In 2018, he won the "Gold Award" of the 12th Hefei Cultural Fair. In 2019, he won the "Hundred Flowers Award" of Fujian Provincial Arts and Crafts. In 2020, its jianzhan was permanently treasured by the Fujian-Taiwan Rim Museum in China.
The author Zhang Changshuo, who was first fired in 2012, has in-depth theoretical discussions on the mud, glaze and products of Jianzhan and has gained a lot. He is good at firing oil drops such as rabbits and other markings. In 2019, extra-large patches of gold partridge spots on black background and silver partridge spots on black background were fired, and on the basis of more than 100 kiln experiments, the dazzling obsidian glaze was successfully created. In 2018, he won the "Gold Award" of the 12th Hefei Cultural Fair. In 2018, he won the "Baowen Award" of the 36th Cultural Festival in Kaifeng, China, and the "Hundred Flowers Award" of Fujian Provincial Arts and Crafts in 2019.
Excerpts from the content
In the electric kiln firing process of the dazzling glaze jianzhan, there are special requirements for the glazing process of the glazing body of the jianzhan. Up to now, the most traditional hand-glazing method is still used in the glazing of Jianzhan, that is, the infiltration method. The fact that other, more modern glazing methods have not yet been used is a return to the tradition of firing by the ancient method of Jianzhan.
Because jianzhan is a continuation of the ancient jianzhan legacy, still maintaining the original historical appearance, in the glazing process using the method of exposed bottom, it can only be the orthotherapy method. In order to avoid the occurrence of waste products caused by the glaze flowing to the bottom of the cup during the high-temperature melting glaze process, the glaze is applied with an exposed tire at the bottom of the cup.
The glazing application method depends on the concentration of the glaze and the duration of the infiltration, both of which must achieve the glaze effect that is just right when firing. To this end, there are extremely harsh requirements in the selection of glaze, glaze concentration, glaze application time, etc.
Generally speaking, the grinding of the dazzling glaze, because it is a high-temperature glaze, determines that it can use raw materials to directly apply glaze, and eliminates the need for glaze (pulp) frits as clinker. And the active ingredients of the glaze can be added to the grinding tank one by one in strict proportion, such as grass and wood ash, calcite or potassium feldspar, high-purity ferric oxide (Fe2O3) red powder, etc. into the grinding tank with water grinding at one time.
Usually, due to the hardness of the glaze ore, even if it is crushed into small particles and then put into a grinding tank, the time to grind it into a pulp is generally about 8 hours. After 8 hours of shutdown, the slurry in the tank is slowly poured into a 300 mesh fine sieve for filtration, and the slurry flowing out through the sieve is the glaze slurry stock.
The glaze must go through more than 10 days of aging period (depending on the external seasonal temperature and other factors), the aging of the glaze pulp, can effectively improve the fluidity and adsorption of the glaze pulp, and can make the performance of the glaze pulp tend to be stable, after reaching a certain saturation, it is conducive to the overall cleaning treatment of the glaze.
"The Origin of the Mechanism of Changing Jianzhan into Glaze" shows us all aspects of the firing process of Jianzhan and allows us to have a deep understanding of Jianzhan. The works tell the history of Jianzhan, explain the production technology of Jianzhan, explain the value of Jianzhan and open the door to the art of Jianzhan for us.
This work has eleven chapters, from history back to reality, from tradition back to the present, from skills to value and other aspects of the narrative, with a large number of practice to explore the Jianzhan process, so that the beauty of Jianzhan art, the exquisite craftsmanship is fully displayed in this work, very suitable for Jianzhan lovers and Jianzhan makers collection reading.
