Speaking of all handmade purple pottery pots, many friends’ attention is mostly focused on the casting process. Because a piece of common mud is pulled into various shapes by both hands, it is very interesting and most common for friends to meet for the first time. As time goes by, the first image of handmade pottery is the casting step.
For the birth of a purple pottery pot, casting is very important, but other steps are not as simple as casting, and bonding is like this. It is rarely mentioned in the public impression, but it is a crucial and difficult step.
I’ve always wanted to share with you the knowledge about the bonding of purple pottery pots in detail, but I have no materials. This time, thanks to the help of the master of Minggu impression, Jiang Yi (left-handed Jiang), we can collect precious bonding materials and tell you about the bonding process of purple pottery pots.
A pot maker’s worktable
1、 The production of a purple pottery pot is a complete and coherent process, and each step is a connecting link between the preceding and the following. Before casting, we should have the shape in mind, so should the bonding. Besides, the strict should also use the relevant data. The mind has the type is the experience, the data is the science which the experience accumulates for a long time.
2、 Take out the mud used for bonding, beat it in both hands for several times, form a strip and cut into several sections for standby. This is not to say that several parts need to be cut into several sections, but more sections should be cut out, because the process of bonding requires grease and cement. A stone ladle pot needs to be bonded to three parts: the spout, the handle, and the bridge shaped knob. It is necessary to cut five or six sections of mud for spare use: three sections are used to make three bonding parts, and the remaining sections are used as putty and mending. Why use the same mud? One is for better bonding and fusion, the other is to make the bonding part consistent with the overall color of the pot after firing.
3、 On a clean workbench, rub out the rudiments of the spout, handle and button. It’s up to the craftsman’s experience to make it thick or thin, to cut it long or short. Rubbing the spout and handle of the pot is very particular about the mood at that time. The ideal appearance can only be made by eye to hand and heart to hand integration. At the same time, whether a pot is delicate or unsophisticated, the thickness of the spout and handle plays a key role. The handlebar of the mouth is rubbed thin, and the left and right match harmoniously. A pot presents a delicate posture, otherwise, it is simple and unsophisticated.
4、 The damage rate and unqualified rate of the bonding parts by hand are relatively high. Therefore, in the case of a private customized pot, two pieces of each part will be rubbed together as a backup. In fact, bonding is not a one-off process. Each step needs a period of time, either to achieve better dry humidity, or to form a better fusion… Therefore, after the components are rubbed, they need to stand for a period of time. After each subsequent step is completed, the corresponding standing is also required.
5、 The parts rubbed by both hands depend on the feeling. It is common that the parts can not meet the standard. Therefore, it is necessary to add mud and further shape. Take the spout as an example. The spout of a stone ladle is thick and thin, and the bonding part should be made into the same inclined plane as the body of the pot. If the thickness is not up to standard, the excess mud should be scraped off bit by bit, and the whole body can not be damaged. The mud has a considerable degree of moisture, scraping force is too large, easy to cause deformation, so the coarse and fine processing often need to wipe off countless times. The handle and button need to be molded accordingly.
6、 Starting from the center of the spout section, take out the mud in a circle; take one end to the middle, and change the other end until the two ends are connected to form a hollow. The three parts will be polished, straightened and ironed, and placed on the workbench for the next key bonding.
7、 Try to install the spout on the body of the pot and adjust the angle until it is close to the slope of the body. With the help of vernier caliper, adhesive calibrator and other tools, determine the bonding position of the spout and mark it.
8、 The water holes should be arranged in order with the same interval. Whether viewed horizontally, vertically or obliquely, the water outlet is in a straight line. And the internal and external should use the corresponding tools to manage the standards and regulations.
9、 Rough treatment was made on the bonding part of the body and the adhesive surface of the spout for better bonding and fusion. Apply grease and paste the spout to the body of the pot; adjust the spout to the desired position with the help of calibration tool. After the handle and button are bonded in the same way, observe whether the three parts are in the same straight line and adjust them in place with the help of calibration tool.
10、 We have mentioned before that there are two kinds of bonding: open connection and concealed connection. In order to make the spout, handle and button of the pot naturally, they are integrated with the body of the pot. The rubbing is not in place, and the molding process does not reach the optimal thickness and inclination. After bonding, a large amount of mud is needed. Manual mud mending needs to be done in circles, little by little, and repeated several times. And as I mentioned earlier, after each step is completed, it should be left standing for a period of time, so that the bonding can be better integrated. After a circle of mud is filled, it needs a long time to rest. Therefore, although it is not difficult to make up the mud, it needs a lot of time and patience.
11、 At this point, the main process of bonding is completed. After the mud is added, further care is carried out, and then it is left to be burned for the next more severe test. I’m here to share with you as much as possible in detail, in order to ceramic friends can intuitively understand the bonding process of purple pottery pot. However, when I look back on every scene and every step in the collection of materials, I still feel that the process described by these words is simple and can not convey the temperature of the hand.
Most of the time, I think, why do you value handwork so much? What’s the significance of handcraft? On the way back from the collection of materials that day, I suddenly had the answer: the significance of handmade is that a person sitting at the work desk, spending part of his life there, and making a work that decorates the world more beautiful and people’s life more wonderful.
Thanks again for the help of Minggu impression master Jiang Yi. Thank you!
