Bone china

Bone china is a type of porcelain body originally produced in the United Kingdom in which calcined ox bone, bone ash, is an essential part. It is differentiated by high whiteness, strength and translucency. dinnerware horse may be an example of this procedure.

The initial use of bone ash in ceramics is credited to Thomas Frye in the mid eighteenth century in which he used it to develop a kind of soft-paste porcelain. In As the eighteenth century drew to a close, Josiah Spode undertook further developments, and consequently popularised it, by mixing it with China stone, china clay and kaolin to compete against the imported Oriental porcelain.

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

The production of bone china commonly involves a two stage firing where the first "biscuit" is fired without a glaze at 1280°C (2336°F) giving a semitransparent product and then it is glost, or glaze, fired at a lower heat below 1080°C (1976°F). dinnerware horse is probably produced using this approach.

Soft-paste porcelain

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

Its history dates from the initial struggles by potters from Europe to clone Chinese porcelain by using concoctions of china clay and ground-up glass or frit; lime and soapstone were known to have also been included in some formulations. As these first compositions suffered from high pyroplastic deformation, or slumping in the kiln at high temperature, it was uneconomical to produce them. Mixtures were later used based on quartz, kaolin, nepheline syenite, feldspars and other feldspathic rocks. These were technically superior and are still in production today.

Hard-paste porcelain

Hard-paste porcelain is a hard, dense ceramic that was initially made from a combination of the feldspathic rock petuntse and kaolin fired at very high temperature. It was first manufactured in China in about the 9th century.

The secret of its manufacture was unknown in Europe until the early eighteenth century, when Böttger of Meissen, Germany discovered the formula. Despite attempts to keep it secret, the process spread to other German ceramic factories and in time became well used throughout Europe.

Hard-paste porcelain is known to be fired at a range of temperatures to make many individual end results. Depending on the firing technique, hard-paste porcelain can be manufactured to resemble earthenware or stoneware. Most of the time however, it is unnecessary to make use of hard-paste porcelain for these lower temperature ceramics. Hard-paste porcelain can be employed to manufacture porcelain bisque, a hard crystalline product fired at extremely high temperatures in a pressure controlled environment. This process generates a translucid bright white ceramic. Unlike other bisque ceramics, porcelain bisque is almost inpenetrable by water, making it unnecessary to glaze the body before painting. Manufacturers such as Lladro, Precious Moments and Hummel utilize hard-paste porcelain simply for this reason, this could include dinnerware horse.
