Manufacture of ceramic products made by manual casting in several stages:
You can read about the development of the bottle’s prototype and creating a plaster cast in the service "Creating the bottle’s model ", and now let’s take a closer look at the process of making the pottery by casting method.
A slip is a mixture of clay for ceramics in accordance with the traditional recipe or a special company’s recipe. The mixture for casting the ceramic products includes lump clay, white clay, talc, various minerals and other admixtures that hold the clay during glazing the future product. All ingredients are mixed with 40 percent water solution, and then the mixture is passing through a filter to remove unnecessary water.
To avoid air bubbles in a ready product, cooked clay mixture is poured into a dry manufacturing form under steady pressure. Cast slowly absorbs water and a thin ceramic layer stays moist. Half an hour later ceramic hardens and the excess fluid is drained. The surpluses are cut off on top of casting, and in an hour you can extracta ceramic item from the mould. At this stage, the ceramic product must be handled very carefully, evenly spreading the pressure to avoid damaging the product. Strong pressure can cause some imprints on the ceramic surface. These imprints will appear only during the glazing and this item will go to the spoilage.
After drying the product,professionals gently manually rub a seam, which is formed by the junction of parts of plaster form. To align the bottom and a neck, a ceramic item is rubbed on a wet rock, and the surface is smoothed with the help of a wet sponge.
The surface of clay ceramics remains matte, unlike of stoneware, which has a glossy surface immediately after glazing. To make clay pottery luster and color, different glaze, paint and enamel is applied on the surface. At the end of the decoration masters cover the product entirely with transparent glaze that gives to the product very glossy shine and extra protection from mechanical impact.
After glazing and decorating all the items are placed into a large oven for several hours, and the temperature rises up to 1250 °C. Ready product of the desired thickness is taken from the mould manually and additional details are glued.
