Expansive clay is a clay soil that is prone to large volume changes (swelling and shrinking) that are directly related to changes in water content. Soils with a high content of expansive minerals can form deep cracks in drier seasons or years; such soils are called vertisols.
The Unified Soil Classification System (USCS) is a soil classification system used in engineering and geology to describe the texture and grain size of a soil. The classification system can be applied to most unconsolidated materials, and is represented by a two-letter symbol.
Montmorillonite is a very soft phyllosilicate group of minerals that form when they precipitate from water solution as microscopic crystals, known as clay. It is named after Montmorillon in France. Montmorillonite, a member of the smectite group, is a 2:1 clay, meaning that it has two tetrahedral sheets of silica sandwiching a central ...
Huishan clay figurine ( Chinese: 惠山泥人; pinyin: Huìshān ní rén) is a traditional Chinese folk art in Wuxi, Jiangsu Province, China, with a history of more than 400 years. [1] [2] The production of Wuxi Huishan clay figurines began at the end of the Ming dynasty and developed in the Qing dynasty with specialized Huishan clay ...
Clay is a type of fine-grained natural soil material containing clay minerals [1] (hydrous aluminium phyllosilicates, e.g. kaolinite, Al 2 Si 2 O 5 ( OH) 4 ). Most pure clay minerals are white or light-coloured, but natural clays show a variety of colours from impurities, such as a reddish or brownish colour from small amounts of iron oxide.
Ceramic material is an inorganic, metallic oxide, nitride, or carbide material. Some elements, such as carbon or silicon, may be considered ceramics. Ceramic materials are brittle, hard, strong in compression, and weak in shearing and tension. They withstand the chemical erosion that occurs in other materials subjected to acidic or caustic ...
Bidriware is a metal handicraft from the city of Bidar in Karnataka, India. It was developed in the 14th century C.E. during the rule of the Bahmani Sultans. [1] The term "bidriware" originates from the township of Bidar, which is still the chief center of production. [2] The metal used is white brass that is blackened and inlaid with silver. [2]

Clay is a very fine-grained geologic material that develops plasticity when wet, but becomes hard, brittle and non–plastic upon drying or firing. [2] [3] [4] It is a very common material, [5] and is the oldest known ceramic. Prehistoric humans discovered the useful properties of clay and used it for making pottery. [6]
Garden gnome: a small, generally colorful gnome statuette. Human form: a depiction of a human being. Human form lawn ornaments can be two-dimensional, generally vertically supported by being thrust in the ground, or three-dimensional. Examples of human form lawn ornaments include the concrete Aboriginal, lawn jockey and groomsman.
