The leaching or alteration leaves flat, plate-like kaolinite crystals that, under very high magnification, are seen to be in stacks. Ball Clay is a variety of Kaolinite, like china-clay, but has a higher plastici Because of its unique properties, it is logical to assume that ball clay is a particular clay mineral. The fine particles present also increase green strength of the dry clay body so dry ware is sturdier. World leading supplier of minerals for tile bodies, frits, glazes and engobes. Used with kaolin, feldspar and quartz in tableware and whiteware, ball clay confers high plasticity and a good white-fired color to the end product. Besides kaolinite, the kaolin also contains quartz, feldspar, mica and other minerals found in the parent rock. Imerys Ceramics’ guaranteed consistent minerals help you to maintain constant high yields during the production of insulators. Cost effective and long term raw materials & bodies to Technical Ceramic manufacturers. Because of the increased shrinkage, ball clays are almost never used alone in a clay body, but rather are blended with kaolins and non-plastic materials like quartz sand. It is combined with other ingredients such as kaolin, silica sand and flux and is a vital part of the mix even in small quantities. Ball clay is a mineral formed from the weathering and transportation by water of parent rocks which are deposited in ancient river basins from where it is extracted. The majority of ceramic clays used around the world are kaolins. Imerys Ceramics has at its disposal ball clays with a range of different properties. In the process of transport and deposition, ball clays can become contaminated with plant matter (organic materials). Leader in the development of kiln furniture solutions for technical ceramics manufacturers. Westerville, OH 43082, © 2020 The American Ceramic Society, all rights reserved. The majority of ceramic clays used around the world are kaolins. Technically speaking, all ball clays are mostly kaolinite, the same clay mineral that makes up kaolins. This is because increasing quartz content reduces fired-body expansion. Typically, the parent mineral of earthenware is mica rather than feldspar. In this way, feldspar is altered into kaolinite clay. It consists of three major minerals that are kaolinite, mica & quartz. Ball clay has a lot of great benefits, especially in ceramics. Most of the clay on earth began life as molten rock that solidified slowly into feldspar and mica. By blending selected clays from different locations Imerys Ceramics can provide high quality products for a range of ceramic applications. The Imerys Ceramics ball clay references come from England, France, Thailand and the United States. Kiln furniture performance is a key factor in manufacturing high quality tableware ceramics. From your first installation to the optimization of existing lines, Imerys Ceramics is your partner of choice to meet your technical and business challenges. Surface deposits of kaolin are quite soft and may be eroded by wind or, more often, by water. Imerys Ceramics’ mineral solutions have a number of unique properties: Highly controlled rheological properties. We also make use of blending platforms in India, Indonesia and Brazil to ensure that we produce ball clays that address the specific technical challenges of each region. Imerys Ceramics has the largest product portfolio on the market: ball clays, including English references, extra white kaolins, a range of chamotte, feldspars and talc for body and glaze solutions. Sometimes kaolin is very near or at the surface of the earth or becomes exposed over time. Erosion moves the stacks of kaolinite crystals downhill or downwind. These sectors account for over 80% of total sales. Ball clays share four common characteristics—particle size, shrinkage, variable quartz, and organic content. World N°1 in prepared bodies & minerals for sanitaryware. Please call: 844-269-0391, 550 Polaris Parkway, Suite 510 Ball clay — is a plastic clay used in the ceramic industry to provide strength and malleability to a ceramic body prior to firing. Technically speaking, all ball clays are mostly kaolinite, the same clay mineral that makes up kaolins. This item will be permanently deleted and cannot be recovered. Facts and Formation Ball Clays is a fine-grained, highly plastic sedimentary clay, which fire to a light or near white color. Ball clay is a mineral formed from the weathering and transportation by water of parent rocks which are deposited in ancient river basins from where it is extracted. The answer is particle size. All influence how ball clays perform in a particular clay body or glaze.
