Mechanical Properties of Ceramics and Glass
– … This came in a time in history when the “Do It Yourself” attitude was in full swing with general businesses such as: Home Depot, Lowe’s, Michaels, Hobby Lobby, etc. were all part of an exploding craft industry. Today more than 1800 studios exist in the world, which is up from 50 studios in 1995. Background: There are three basic categories of ceramics: earthenware, stoneware, and porcelain. Earthenware is the longest established type of pottery, dating back to the Stone Age. Earthenware is the softest type, resulting in the lowest temperature needed to make (around 1000-1200 degrees Celsius)….
Archaeomagnetism in Archaeological Sites
– Objects under this category are not only easier to find than most other objects at archaeological sites, but in certain cases where their kiln baked position with respect to the vertical is known ,they can also be used to estimate the age of the object. This can be determined by measuring the inclination of the remanent magnetization which occurred at the time it was baked. The magnetic inclination can be compared with the history of the variation of the earth’s magnetic inclination known through historical records and other fire-baked clay objects already dated by other methods….
Taking a Look at Hollow Slip Casting
– … A deflocculant is an electrolyte enables fluidity with a minimal amount of water. Less water results in far less shrinkage and greater strength. On the other hand, a flocculant requires more time for the slip to cast because the cast gets saturated more quickly. Flocculation is often used to thicken up glaze to help keep it in suspension and to improve application properties. Procedure In hollow slip casting, a deflocculated and concentrated cast slip is poured into a plaster mold. Water from the slip is absorbed by the mold until a layer of solid clay takes the shape of the interior of the mold….
The History of Clay Bricks
– … As reported, prior to 2500 BCE, clay bricks were fashioned by hand and set to dry using only the sun. The aforementioned date marks the time when clay bricks were formed with molds and dried by baking with fire (The history of clay, n.d.). Throughout the centuries clay bricks have been utilized to construct remarkable historical landmarks, [I]f you believe the Old Testament then you might know the Tower of Babel was constructed of brick. So for that matter of fact was Babylon, the Sakkova stepped Pyramid, the Great Wall of China and Bengal’s Paharpur Temple to name but a few other mighty ancient structures….
– Takatori Ware Takatori ware is well known to practitioners of the tea ceremony, but its relatively limited and specialized production has caused its four hundred year history to be overlooked by many lovers of Japanese ceramics. The various tribulations and triumphs of the Takatori potters are remarkably well documented in a number of historical sources dating from the Edo period (1615-1867), bringing a moving, human side to the story of these elegant wares. Furthermore, archaeological excavation of a majority of the seven Takatori kilnsites, has helped to define the stylistic development of the wares….
