Given the question: Information: - Royal Tichelaar Makkum is a Dutch pottery company , based in Makkum . After initially producing bricks and later pottery and tiles , the company has focused on traditional decorative pottery since 1890 . As the company in Makkum has always made ceramics , Royal Tichelaar Makkum is regarded as one of the oldest companies in the Netherlands . - Pottery is the craft of making ceramic material into pots or potterywares using mud. Major types of potterywares include earthenware, stoneware and porcelain. The place where such wares are made by a "potter" is called a "pottery" (plural "potteries"). The technical definition of "pottery" used by the American Society for Testing and Materials (ASTM) is "all fired ceramic wares that contain clay when formed, except technical, structural, and refractory products." - Porcelain is a ceramic material made by heating materials, generally including kaolin, in a kiln to temperatures between . The toughness, strength, and translucence of porcelain, relative to other types of pottery, arises mainly from vitrification and the formation of the mineral mullite within the body at these high temperatures. - Clay is a fine-grained natural rock or soil material that combines one or more clay minerals with traces of metal oxides and organic matter. Clays are plastic due to their water content and become hard, brittle and nonplastic upon drying or firing. Geologic clay deposits are mostly composed of phyllosilicate minerals containing variable amounts of water trapped in the mineral structure. Depending on the soil's content in which it is found, clay can appear in various colours from white to dull grey or brown to deep orange-red. Although many naturally occurring deposits include both silts and clay, clays are distinguished from other fine-grained soils by differences in size and mineralogy. Silts, which are fine-grained soils that do not include clay minerals, tend to have larger particle sizes than clays. There is, however, some overlap in particle size and other physical properties. The distinction between silt and clay varies by discipline. Geologists and soil scientists usually consider the separation to occur at a particle size of 2 m (clays being finer than silts), sedimentologists often use 45 m, and colloid chemists use 1 m. Geotechnical engineers distinguish between silts and clays based on the plasticity properties of the soil, as measured by the soils' Atterberg limits. ISO 14688 grades clay particles as being smaller than 2 m and silt particles as being larger. - Stoneware is a rather broad term for pottery or other ceramics fired at a relatively high temperature. A modern technical definition is a vitreous or semi-vitreous ceramic made primarily from stoneware clay or non-refractory fire clay. Whether vitrified or not, it is nonporous (does not soak up liquids); it may or may not be glazed. Historically, across the world, it has usually been developed after earthenware and before porcelain, and has often been used for high-quality as well as utilitarian wares. Stoneware is not recognised as a category in traditional East Asian terminology, and much Asian stoneware, such as Chinese Ding ware for example, is counted as porcelain by local definitions. Terms such as "porcellaneous" or "near-porcelain" may be used in such cases. One widely recognised definition of stoneware is from the Combined Nomenclature of the European Communities, a European industry standard. It states: - Earthenware is glazed or unglazed nonvitreous pottery which has normally been fired below 1200C. Porcelain, bone china and stoneware, all fired at high enough temperatures to vitrify, are the main other important types of pottery. What is the relationship between 'royal tichelaar makkum' and 'earthenware'?
