After separation, clay needs to be moistened in order to form a mass similar to a test, which is then blended with admixtures. The most common way, which is likely used and in the past is a slipping. The mass is formed in a crowd, and the potter walking on it, pushing material from the top to mix it with the one at the bottom. Though hard, this is the way fast and suitable for large amounts of clay. For smaller quantities, the same result is achieved by mixing by hand. The mass rotates – unfolds / turns, which repeats until all the primers are not Equally distributed in mass. In the process of mixing, it is very important that this is done way eliminate the air pockets formed in the previous steps of preparing the raw material . Hand blending is used even after the initial hit. Sometimes The masters decide on one or another technique, depending on how much the container will be Made: if smaller quantities are planned, the dough will be mixed manually.

In order to prevent the clay prone and cling to the work surface, pottery usually pill some materials (ash, sand, dusted clay, etc.), through which it is placed clay dough, similar to the method of mixing the flour test. Primets are added over clay mass. Then the dough flesh. Archeologically, it is impossible to distinguish this added materials of the primer. The process of mixing the mass can be repeated several times: muddy clay mixes with water, flesh, and then crumbles again and the entire process is repeated. Traditional potters know that the mass is usually the most common feeling. Besides, that would check that the mass of good consistency, take a small clump of clay and press it tilted between fingers and then thrown to check “stickiness” (i.e., plasticity), and a little masses rub through the tongue to check the “roughness” (i.e., the presence of an admixture).

For archeology, it is particularly important that traditional communities are common the case that they are not added at all to the clay, but to select clay in the natural. The condition meets the needs of the potter or mixed with different clays from several bearings to get it suitable mass. In these technologies there is no mixing of matter, but the process of mixing the test is considered to be crucial because it homogenizes the clay and so it’s preparing for the design process. Since the mixing is done and the consistency of the mass reached, the mass is divided into balls of a certain size, depending on the size of the bowl being made. In more advanced technologies, mixing the admixture is done when the clay is in shape slip, so that the admixtures that are mixed with the spatula are added to the liquid structure thus collected some other tool; After this procedure, the slip is drained. Consumed mass can be used immediately, but it can also be stored in order to design was performed later. The most common case is the storage of clay that has passed only separation process, and then stored in a dry state.

The production of ceramic vessels using molds is common in traditional communities and it was probably also popular at the time of prehistoric times. At the beginning, it must be clarified that this is not a mold that is known from modern, highly specialized and industrial production. On the contrary, it’s about simple techniques, and as molds, no purpose-built objects are used, but what is most accessible from the environment. These are usually ceramic vessels, often broken or damaged, which are no longer suitable for their primary function. Darfur peoples in Sudan cover a shallow pit with palm fiber pillows, and over that, they place a clay ball; The ball is simultaneously turning and striking with a stone beam until the shape of the bowl is formed.

The usual procedure is to make a piece of clay previously prepared by tapping or rolling to get a “pancake” pressure from the outside or inside the mold. The molds can be convex, so the pancake is glued on their outside, or concave, in which the pancake is pressed from the inside. Similar to the mixing of the mass, the molds are usually sprinkled with some material (ash, powdered clay, fine sand and the like), so that the pancake is not glued to the mold. Different ways to press pancakes on the mold: this can be done by pressing the hand, but also by tapping or hitting a piece of stone or some tool. Pancake on the mold is usually left to dry before removing. In this respect, it is easier to use concave molds, since the clay during drying will be collected and separated.
