POTTERY MAKING
Pottery is the process and the products of forming vessels and other objects with clay and other ceramic materials, which are fired at high temperatures to give them a hard, durable form. Major types include earthenware, stoneware, and porcelain.
The place where such wares are made by a potter is also called a pottery The definition of pottery used by the American Society for Testing and Materials is "all fired ceramic wares that contain clay when formed, except technical, structural, and refractory products. In archaeology, especially of ancient and prehistoric periods, "pottery" often means vessels only, and figures of the same material are called "terracottas." Clay, as a part of the materials used, is required by some definitions of pottery, but this is dubious.







Pottery from Székely Land, Romania, on sale in Budapest. Pottery is one of the oldest human inventions, originating before the Neolithic period, with ceramic objects like the Gravettian culture Venus of Dolní Věstonice figurine discovered in the Czech Republic dating back to 29,000–25,000 BC, and pottery vessels that were discovered in Jiangxi, China, which date back to 18,000 BC.
Early Neolithic and pre-Neolithic pottery artifacts have been found, in Jōmon Japan the Russian Far East (14,000 BC), Sub-Saharan Africa (9,400 BC), South America (9,000s-7,000s BC), and the Middle East Pottery is made by forming a ceramic (often clay) body into objects of the desired shape and heating them to high temperatures (600-1600 °C) in a bonfire, pit, or kiln and induces reactions that lead to permanent changes including increasing the strength and rigidity of the object.
Much pottery is purely utilitarian, but much can also be regarded as ceramic art. A clay body can be decorated before or after firing. Clay Pot (Ghaila) in Nepal Traditional pottery, Bangladesh The pottery market in Bourbon, Niger. Clay-based pottery can be divided into three main groups: earthenware, stoneware, and porcelain. These require increasingly more specific clay material, and increasingly higher firing temperatures. All three are made in glazed and unglazed varieties, for different purposes.
All may also be decorated by various techniques. In many examples, the group a piece belongs to is immediately visually apparent, but this is not always the case.

The fritware of the Islamic world does not use clay, so technically falls outside these groups. Historic pottery of all these types is often grouped as either "fine" wares, relatively expensive and well-made, and following the aesthetic taste of the culture concerned, or alternatively "coarse", "popular", "folk" or "village" wares, mostly undecorated, or simply so, and often less well-made.

PREGNANCY EXERCISE Regular aerobic exercise during pregnancy appears to improve (or maintain) physical fitness. Physical exercise during pregnancy does appear to decrease the need for C-section. Bed rest, outside of research studies, is not recommended as there is no evidence of benefit and potential harm. The Clinical Practice Obstetrics Committee of Canada recommends that "All women without contraindications should be encouraged to participate in aerobic and strength-conditioning exercises as part of a healthy lifestyle during their pregnancy". Although an upper level of safe exercise intensity has not been established, women who were regular exercisers before pregnancy and who have uncomplicated pregnancies should be able to engage in high-intensity exercise programs. In general, participation in a wide range of recreational activities appears to be safe, with the avoidance of those with a high risk of falling such as horseback riding or skiing or those that carry a risk

SMITHY SKILL                                                                  https://youtu.be/k6-KsoYYoYE A blacksmith is a metalsmith who creates objects from wrought iron or steel by forging the metal, using tools to hammer, bend, and cut (cf. tinsmith). Blacksmiths produce objects such as gates, grilles, railings, light fixtures, furniture, sculpture, tools, agricultural implements, decorative and religious items, cooking utensils, and weapons. There was a historical opposition between the heavy work of the blacksmith and the more delicate operation of a whitesmith, who usually worked in gold, silver, pewter, or the finishing steps of fine steel. The place where a blacksmith works are called variously a smithy, a forge, or a blacksmith's shop. While there are many people who work with metal such as farriers, wheelwrights, and armorers, in former times the blacksmith had a general knowledge of how to make and repair many things, from the most complex of weapons and armor to sim

Prosthesis In  medicine , a  prosthesis  from  Ancient Greek   prosthesis , or  prosthetic  implant   is an artificial device that replaces a missing body part, which may be lost through trauma, disease, or a condition present at birth ( congenital disorder ).  Prostheses are intended to restore the normal functions of the missing body part.   Amputee  rehabilitation is primarily coordinated by a  physiatrist  as part of an interdisciplinary team consisting of physiatrists, prosthetists, nurses, physical therapists, and occupational therapists.   Prostheses can be created by hand or with  computer-aided design  (CAD), a software interface that helps creators design and analyze the creation with computer-generated  2-D  and  3-D graphics  as well as analysis and optimization tools. Iron prosthetic hand believed to have been owned by Götz von Berlichingen (1480–1562) Over the years, there have been advancements in artificial limbs.
