Antique Lighting – Antique Lamps Porcelain biscuit
Biscuit porcelain or porcelain biscuit, is named after his initial shot or the first, when the fragile porcelain could be snapped like a cookie. Biscuit porcelain is also widely known as “biscuit” Ware unglazed and more popularly as “parian” ware.
All bisque or parian porcelain is unglazed and the Victorian era was admired for its sculptural qualities. The name “Paros” is actually attributed to Thomas Minton, the famous 19th century English potter, who coined the name after Paros Paros, the Greek island that extracts much pure white marble sculptural used in studios.
Of course, the initiator of the porcelain was China, including unglazed porcelain bisque white. Known to the Chinese potters as “Fan Tsu.” China has been before the 18th century, the sole producer of porcelain in the world and therefore is commemorated by the standard name we give to china, China!
When the porcelain gets its first shot, it is porous. It is then glazed and annealing. The second firing caused the glaze to fuse with the shape and become porous vitrified, or “like glass.” This “white glass” State, it is then moved to the decoration department to be painted by skilled painters porcelain, or for transfer printed. At the finish of the process of decoration, the shape is then annealed to set the colored enamels.
If foil is being applied, the shape is drawn again with each shot at a lower temperature than the last, the heat is gradually reduced.
In production biscuit porcelain, porcelain is left in the white and unglazed. Glazes have a huge advantage for manufacturers of porcelain as defects glazes hide. With biscuit, this element is missing useful and quality is entirely dependent on the detailed modeling and control production.

Bisque, with a new cream was relaunched in 1846 and again in the late 19th century. It has a range of colors, from white to cream and was also known as “Paros” a reference to the white marble of the Greek island of Paros, highly sought after by sculptors. Bisque was much more favorable throughout the period Victorian because of its appearance rather sculpted.

While we always keep the “biscuit porcelain” name, modern production methods now produce a hard, strong, ceramic body, without the fragility of early cookie that need to stabilize the windows form.
In Europe, the pure white porcelain biscuit, just like a ballerina, took the stage in the 1750s with the production of superb busts and groups included in dazzling white marble Sosie a similar.
At the factory of Vincennes, a series of beautiful children, modeled from drawings by Boucher and modeled Blondeau were produced by other plants with mid 18th century, as Sèvres Mennecy and producing quality issues figure sublime.
In 18th century England, the Derby plant produces finely detailed figures bisque undecorated. With numbers in English being conventionally decorated in color, these figures must be looked exceptional.
The English Rising of the 18th century came in 1774 with the discovery Josiah Wedgwood, jasper. Jasper is a fine-grained, unglazed stoneware, now so well known to be seen as synonymous with the name of Wedgwood. Japanese Clothing has been copied by the French Sevres bisque porcelain and other French and German plants.
At the end of the 18th century, as usual, tastes have changed and the no frills, neo classicism prevailed. Biscuit porcelain reached new heights of refinement with elegant Regency style. Bisque library busts, Wedgwood jasper white unglazed biscuit and elegant styles both English and French.
Bisque, with a new cream has been reintroduced by Copeland in Staffordshire in 1846 and was soon copied by other manufacturers English and American.
And now for the technical!
The production of porcelain bisque figure, or the base of the lamp starts with the eye of the creator, who, with sketchbook and pencil, outlines the design idea. This idea, of course, be framed by the contemporary styles of the time.
Bisque porcelain, like all complex shapes in ceramics, is cast or molded slides. Slip is liquid slurry, which is made of potter’s clay mixed with water to a semi liquid is creamy literally cast in plaster preformed mold of Paris to take shape.
Slip is the raw material behind the beautiful porcelain we see. This liquid is porcelain a mixture of kaolin, feldspar and flint, finely ground. Kaolin herren strickjacke is naturally occurring, very fine clay with a high percentage of silicate. The feldspar is a crystalline mineral, also with a high content of silicate and flint is a finely ground quartz disk.
This lists only the main content of this mixture porcelain, which was refined and developed over hundreds of years. Chemistry is much more complex with the potassium, sodium and calcium contributes to the finished product.
Both pottery and porcelain are made by pouring the slip into plaster molds, plaster absorbs water from the slip, causing a firm layer to form, the surplus is then paid off.
It is interesting to note that the tradition of casting slip Plaster of Paris, preformed mold is not new, the process being introduced in England in 1745 or so, deemed by a potter named Ralph Daniels of Cobridge.
When the remaining schedule has become hard cheese or sometimes called “leather hard”, the plaster molds are removed and forms of slip cast assembled to produce the desired pattern.
Traditionally, the assembly function was performed by a member Staff called the “repair”. It was his job to remove all seams and smooth all traces of mold. This finishing process is the same as that of slip used today to act as a glue.
When assembly is complete, forms are carefully dried air to allow parts to dry. Now completed form is sent to the oven for cooking.
Some things never change and production base of this elegant china, it seems is one of them.
