Hermann August Seger
Hermann Seger (1832–1893) was a German ceramicist who is widely credited with pioneering the development of the pyrometric cone, which enabled the rapid growth of the ceramic industry around the turn of the century. Biography Seger was born in the German Province of Posen in 1839 to wealthy parents and studied under various ceramic scientists at the Königliche Bauakademie in Berlin (now Technische Universität Berlin). After graduating he managed an alum and vitriol processing plant at Kreuzkirche at Neuwied on the Rhine. In 1868 he graduated from the University of Rostock and briefly managed a chemical factory in Sweden. Seger was inspired by the significant advances being made in most fields of science and technology at the time and became interested in advancing the field of ceramic science in a similar manner. He became editor of a ceramic trade journal in 1872 and used his new position to draw attention to various advances being made abroad, such as the continuous ki ...

University Of Rostock
The University of Rostock () is a public university located in Rostock, Mecklenburg-Vorpommern, Germany. Founded in 1419, it is the third-oldest university in Germany. It is the oldest university in continental northern Europe and the Baltic Sea area, and 8th oldest in Central Europe. It was the 5th university established in the Holy Roman Empire. The university has been associated with three Nobel laureates: Albrecht Kossel, Karl von Frisch and Otto Stern. It is a member of the European University Association. According to a ranking published by ''Times Higher Education'' in 2018, it is the most beautiful university in Germany and the fourth most beautiful university in all of Europe. The language of instruction is usually German, and English for some postgraduate studies. History 1419–1919 The university was founded in 1419 by confirmation of Pope Martin V and thus is one of the oldest universities in Northern Europe.

19th-century German Inventors
The 19th century began on 1 January 1801 (represented by the Roman numerals MDCCCI), and ended on 31 December 1900 (MCM). It was the 9th century of the 2nd millennium. It was characterized by vast social upheaval. Slavery was abolished in much of Europe and the Americas. The First Industrial Revolution, though it began in the late 18th century, expanded beyond its British homeland for the first time during the 19th century, particularly remaking the economies and societies of the Low Countries, France, the Rhineland, Northern Italy, and the Northeastern United States. A few decades later, the Second Industrial Revolution led to ever more massive urbanization and much higher levels of productivity, profit, and prosperity, a pattern that continued into the 20th century. The Catholic Church, in response to the growing influence and power of modernism, secularism and materialism, formed the First Vatican Council in the late 19th century to deal with such problems and confirm ce ...

Mole (unit)
The mole (symbol mol) is a unit of measurement, the base unit in the International System of Units (SI) for ''amount of substance'', an SI base quantity proportional to the number of elementary entities of a substance. One mole is an aggregate of exactly elementary entities (approximately 602 sextillion or 602 billion times a trillion), which can be atoms, molecules, ions, ion pairs, or other particles. The number of particles in a mole is the Avogadro number (symbol ) and the numerical value of the '' Avogadro constant'' (symbol ) expressed in mol−1. The relationship between the mole, Avogadro number, and Avogadro constant can be expressed in the following equation:1\text = \frac = \frac The current SI value of the mole is based on the historical definition of the mole as the amount of substance that corresponds to the number of atoms in 12 grams of 12C, which made the molar mass of a compound in grams per mole, numerically equal to the average molecular mass or ...

Ceramic Art
Ceramic art is art made from ceramic materials, including clay. It may take varied forms, including artistic pottery, including tableware, tiles, figurines and other sculpture. As one of the plastic arts, ceramic art is a visual art. While some ceramics are considered fine art, such as pottery or sculpture, most are considered to be Decorative arts, decorative, Industrial design, industrial or Applied arts, applied art objects. Ceramic art can be created by one person or by a group, in a pottery or a ceramic factory with a group designing and manufacturing the artware. In Britain and the United States, modern ceramics as an art took its inspiration in the early twentieth century from the Arts and Crafts movement, leading to the revival of pottery considered as a specifically modern craft. Such crafts emphasized traditional non-industrial production techniques, faithfulness to the material, the skills of the individual maker, attention to utility, and an absence of excessive ...

Pyrometric Cones
Pyrometric cones are pyrometric devices that are used to gauge heatwork during the firing of ceramic materials in a kiln. The cones, often used in sets of three, are positioned in a kiln with the wares to be fired and, because the individual cones in a set soften and fall over at different temperatures, they provide a visual indication of when the wares have reached a required state of maturity, a combination of time and temperature. Pyrometric cones give a ''temperature equivalent''; they are not simple temperature-measuring devices. Definition The pyrometric cone is "A pyramid with a triangular base and of a defined shape and size; the "cone" is shaped from a carefully proportioned and uniformly mixed batch of ceramic materials so that when it is heated under stated conditions, it will bend due to softening, the tip of the cone becoming level with the base at a definitive temperature. Pyrometric cones are made in series, the temperature interval between the successive cones ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Whiteware
Pottery is the process and the products of forming vessels and other objects with clay and other raw materials, which are fired at high temperatures to give them a hard and durable form. The place where such wares are made by a ''potter'' is also called a ''pottery'' (plural ''potteries''). The definition of ''pottery'', used by the ASTM International, is "all fired ceramic wares that contain clay when formed, except technical, structural, and refractory products". End applications include tableware, ceramic art, decorative ware, toilet, sanitary ware, and in technology and industry such as Insulator (electricity), electrical insulators and laboratory ware. In art history and archaeology, especially of ancient and prehistoric periods, pottery often means only vessels, and sculpture, sculpted figurines of the same material are called terracottas. Pottery is one of the Timeline of historic inventions, oldest human inventions, originating before the Neolithic, Neolithic period, w ...
