Noborigama
The ''anagama'' kiln (Japanese Kanji: 穴窯/ Hiragana: あながま) is an ancient type of pottery kiln brought to Japan from China via Korea in the 5th century. It is a version of the climbing dragon kiln of south China, whose further development was also copied, for example in breaking up the firing space into a series of chambers in the ''noborigama'' kiln. An ''anagama'' (a Japanese term meaning "cave kiln") consists of a firing chamber with a firebox at one end and a flue at the other. Although the term "firebox" is used to describe the space for the fire, there is no physical structure separating the stoking space from the pottery space. The term ''anagama'' describes single-chamber kilns built in a sloping tunnel shape. In fact, ancient kilns were sometimes built by digging tunnels into banks of clay. The anagama is fueled with firewood, in contrast to the electric or gas-fueled kilns commonly used by most modern potters. A continuous supply of fuel is needed for f ...

Kiln
A kiln is a thermally insulated chamber, a type of oven, that produces temperatures sufficient to complete some process, such as hardening, drying, or chemical changes. Kilns have been used for millennia to turn objects made from clay into pottery, tiles and bricks. Various industries use rotary kilns for pyroprocessing—to calcinate ores, to calcinate limestone to lime for cement, and to transform many other materials. Pronunciation and etymology According to the Oxford English Dictionary, kiln was derived from the words cyline, cylene, cyln(e) in Old English, in turn derived from Latin ''culina'' ("kitchen"). In Middle English the word is attested as kulne, kyllne, kilne, kiln, kylle, kyll, kil, kill, keele, kiele. For over 600 years, the final "n" in kiln was silent. It wasn't until the late 20th century where the "n" began to be pronounced. This is due to a phenomenon known as spelling pronunciation, where the pronunciation of a word is surmised from its spelling an ...

Japanese Pottery
, is one of the oldest Japanese crafts and art forms, dating back to the Neolithic period. Kilns have produced earthenware, pottery, stoneware, glazed pottery, glazed stoneware, porcelain, and blue-and-white ware. Japan has an exceptionally long and successful history of ceramic production. Earthenwares were made as early as the Jōmon period (10,500–300BC), giving Japan one of the oldest ceramic traditions in the world. Japan is further distinguished by the unusual esteem that ceramics holds within its artistic tradition, owing to the enduring popularity of the tea ceremony. Japanese ceramic history records distinguished many potter names, and some were artist-potters, e.g. Hon'ami Kōetsu, Ogata Kenzan, and Aoki Mokubei.Henry Trubner 1972, p. 18. Japanese anagama kilns also have flourished through the ages, and their influence weighs with that of the potters. Another characteristically Japanese aspect of the art is the continuing popularity of unglazed high-fired ston ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shigaraki
is a town located in Kōka District, Shiga Prefecture, Japan. As of 2004, the town has an estimated population of 13,885 and a density of 84.92 persons per km². The total area is 163.5 km². On October 1, 2004, Shigaraki, along with the towns of Kōka, Kōnan, Minakuchi and Tsuchiyama (all from Kōka District), was merged to create the city of Kōka. It also served as the imperial capital for several months in 745, before moving to Heijō-kyō due to a forest fire destroying the palace (Shigaraki Palace). Shigaraki is famous for its ceramic kilns since ancient times. The area is known for its clay beds, and locally mined clay is often used by local potters. Works produced here are known as Shigaraki-yaki. Many local potters use wood fired anagama kilns. Many tanuki Tanuki may refer to: *Japanese raccoon dog (''Nyctereutes viverrinus'' or ''Nyctereutes procyonoides viverrinus''), a mammal native to Japan *Bake-danuki, a type of spirit (yōkai) in Japanese mythology t ...

Six Ancient Kilns
The Six Ancient Kilns (六古窯 Rokkoyō) is a category developed by Koyama Fujio (小山富士夫 1900–1975) in the post-war period to describe the most noteworthy ceramic kilns of Japan. The six kilns are: * Bizen ware (備前焼, Bizen-yaki), produced in Bizen, Okayama * Echizen ware (越前焼, Echizen-yaki), produced in Echizen, Odacho and Miyazaki, Fukui Prefecture * Seto ware (瀬戸焼, Seto-yaki), produced in Seto, Aichi Prefecture * Shigaraki ware (信楽焼, Shigaraki-yaki), produced in Kōka, Shiga, east of Lake Biwa * Tamba ware, also known as Tachikui ware (丹波立杭焼, Tamba-Tachikui-yaki), produced in Sasayama and Tachikui in Hyōgo * Tokoname ware (常滑焼, Tokoname-yaki), produced in Tokoname, Aichi Prefecture The Okayama Prefectural Bizen Ceramic Museum held an exhibition in 2001 about the six kilns.

Countercurrent Exchange
Countercurrent exchange is a mechanism occurring in nature and mimicked in industry and engineering, in which there is a crossover of some property, usually heat or some chemical, between two flowing bodies flowing in opposite directions to each other. The flowing bodies can be liquids, gases, or even solid powders, or any combination of those. For example, in a distillation column, the vapors bubble up through the downward flowing liquid while exchanging both heat and mass. The maximum amount of heat or mass transfer that can be obtained is higher with countercurrent than co-current (parallel) exchange because countercurrent maintains a slowly declining difference or gradient (usually temperature or concentration difference). In cocurrent exchange the initial gradient is higher but falls off quickly, leading to wasted potential. For example, in the adjacent diagram, the fluid being heated (exiting top) has a higher exiting temperature than the cooled fluid (exiting bottom) that ...

Thermodynamics
Thermodynamics is a branch of physics that deals with heat, work, and temperature, and their relation to energy, entropy, and the physical properties of matter and radiation. The behavior of these quantities is governed by the four laws of thermodynamics which convey a quantitative description using measurable macroscopic physical quantities, but may be explained in terms of microscopic constituents by statistical mechanics. Thermodynamics applies to a wide variety of topics in science and engineering, especially physical chemistry, biochemistry, chemical engineering and mechanical engineering, but also in other complex fields such as meteorology. Historically, thermodynamics developed out of a desire to increase the efficiency of early steam engines, particularly through the work of French physicist Sadi Carnot (1824) who believed that engine efficiency was the key that could help France win the Napoleonic Wars. Scots-Irish physicist Lord Kelvin was the first to formulate a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Buttress
A buttress is an architectural structure built against or projecting from a wall which serves to support or reinforce the wall. Buttresses are fairly common on more ancient buildings, as a means of providing support to act against the lateral (sideways) forces arising out of inadequately braced roof structures. The term ''counterfort'' can be synonymous with buttress and is often used when referring to dams, retaining walls and other structures holding back earth. Early examples of buttresses are found on the Eanna Temple (ancient Uruk), dating to as early as the 4th millennium BC. Terminology In addition to flying and ordinary buttresses, brick and masonry buttresses that support wall corners can be classified according to their ground plan. A clasping or clamped buttress has an L shaped ground plan surrounding the corner, an angled buttress has two buttresses meeting at the corner, a setback buttress is similar to an angled buttress but the buttresses are set back from the ...

Arch
An arch is a vertical curved structure that spans an elevated space and may or may not support the weight above it, or in case of a horizontal arch like an arch dam, the hydrostatic pressure against it. Arches may be synonymous with vaults, but a vault may be distinguished as a continuous arch forming a roof. Arches appeared as early as the 2nd millennium BC in Mesopotamian brick architecture, and their systematic use started with the ancient Romans, who were the first to apply the technique to a wide range of structures. Basic concepts An arch is a pure compression form. It can span a large area by resolving forces into compressive stresses, and thereby eliminating tensile stresses. This is sometimes denominated "arch action". As the forces in the arch are transferred to its base, the arch pushes outward at its base, denominated "thrust". As the rise, i. e. height, of the arch decreases the outward thrust increases. In order to preserve arch action and prevent collapse ...
