Bone china

Bone china is a type of porcelain body initially used in the United Kingdom in which calcined ox bone, bone ash, is a critical part. It is differentiated by supreme whiteness, strength and translucency. angela cream soup cup stand may be an example of this process.

The first use of bone ash in ceramics is associated with Thomas Frye in in the late 1740s in which he used it to develop a kind of soft-paste porcelain. In At the close of the eighteenth century, Josiah Spode continued with further developments, and subsequently popularized it, by mixing it with China stone, china clay and kaolin to compete with the imported Oriental porcelain.

The initial basic recipe of six parts bone ash, four parts china stone, and three and a half parts china clay remains the standard English body.

Bone china production ordinarily involves a two stage firing where the initial "biscuit" is fired without a glaze at 1280°C (2336°F) giving a translucid product and then it is glaze, or glost, fired at a lower setting under 1080°C (1976°F). angela cream soup cup stand is probably made using this approach.

Soft-paste porcelain

Soft-paste porcelain is a type of porcelain and consequently a ceramic material.

Its origin dates from the first strivings by European potters to imitate Chinese porcelain by using formulations of china clay and ground-up glass (otherwise known as frit); lime and soapstone were also known to have been used in some mixtures. As these early concoctions were prone to high pyroplastic collapse, or slumping in the kiln at high temperature, it was uneconomical to manufacture them. Compositions were later produced based on feldspars, quartz, kaolin, nepheline syenite and other feldspathic rocks. These were technically superior and are still in production to this day.

Hard-paste porcelain

Hard-paste porcelain is a hard, dense ceramic that was first produced from a concoction of the feldspathic rock petuntse and kaolin fired at very high temperature. It was first manufactured in China around the ninth century.

The secret of its manufacture was not known in Europe until the early seventeen hundreds, when Böttger of Meissen, Germany discovered the formula. Regardless of attempts to keep it secret, the procedure was used by other German ceramic manufacturers and eventually became well used throughout Europe.

Hard-paste porcelain is known to be fired at a range of temperatures to make a multitude of individual end results. Depending on the firing method, hard-paste porcelain can be manufactured to resemble earthenware or stoneware. Most of the time however, it is unnecessary to employ hard-paste porcelain for these lower temperature ceramics. Hard-paste porcelain can be used to manufacture porcelain bisque, a hard crystalline product fired at extremely high temperatures in a pressure controlled environment. This technique generates a semitransparent bright white ceramic. Unlike other bisque ceramics, porcelain bisque is almost inpenetrable by water, therefore it becomes unnecessary to glaze the body before painting. Manufacturers such as Lladro, Precious Moments and Hummel utilize hard-paste porcelain just for this reason, this could include angela cream soup cup stand.
