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 ...
Traditionally made of fine-grained secondary, plastic clays which can be used to shape very large pieces. Fine stoneware: made from more carefully selected, prepared, and blended raw materials. It is used to produce tableware and art ware. Chemical stoneware: used in the chemical industry, and when resistance to chemical attack is needed.
Hard-paste porcelain, sometimes called "true porcelain", is a ceramic material that was originally made from a compound of the feldspathic rock petuntse and kaolin fired at a very high temperature, usually around 1400 °C. It was first made in China around the 7th or 8th century and has remained the most common type of Chinese porcelain. [2] [3]

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]
[4] [5] [6] Clay is the longest-known ceramic material. Prehistoric humans discovered the useful properties of clay and used it for making pottery . Some of the earliest pottery shards have been dated to around 14,000 BCE, [ 7 ] and clay tablets were the first known writing medium. [ 8 ]
Mineral wool is any fibrous material formed by spinning or drawing molten mineral or rock materials such as slag and ceramics. [1] Applications of mineral wool include thermal insulation (as both structural insulation and pipe insulation), filtration, soundproofing, and hydroponic growth medium.
Granite (/ ˈ ɡ r æ n ɪ t / GRAN-it) is a coarse-grained intrusive igneous rock composed mostly of quartz, alkali feldspar, and plagioclase.It forms from magma with a high content of silica and alkali metal oxides that slowly cools and solidifies underground.
