Ceramic
A ceramic is a, non-metallic, solid material comprising an inorganic compound of metal, non-metal or metalloid atoms primarily held in ionic and covalent bonds.
Engineering
Engineering is the creative application of science, mathematical methods, and empirical evidence to the innovation, design, construction, operation and maintenance of structures, machines, materials, devices, systems, processes, and organizations. The discipline of engineering encompasses a broad range of more specialized fields of engineering, each with a more specific emphasis on particular areas of applied mathematics, applied science, and types of application. See glossary of engineering.
Thermal
A thermal column (or thermal) is a column of rising air in the lower altitudes of Earth's atmosphere, a form of atmospheric updraft. Thermals are created by the uneven heating of Earth's surface from solar radiation, and are an example of convection, specifically atmospheric convection. The Sun warms the ground, which in turn warms the air directly above it.
Ceramic
The history of ceramic production in the medieval Muslim world, from the period of the Umayyads in the seventh century to the Ottomans and Safavids in the seventeenth century, attests to the superior creativity and experimentation of Islamic potters, demonstrated through their innovations in shape and design, clay recipes, glazes, and techniques of decoration.
