Antique Gilt Bronze Sevres Porcelain Inset Casket C1860

From the outset the king's clear aim was to produce Sevres Porcelain that surpassed the established Saxony works of Meissen and Dresden. Though the French lacked an ample supply of kaolin, a required ingredient for hard-paste porcelain (pate dure), their soft-paste porcelain (pate tendre) was fired at a lower temperature and was thus compatible with a wider variety of colours and glazes that in many cases were also richer and more vivid. Unglazed white Sevres Porcelain "biscuit" figurines were also a great success. However, soft-paste Sevres Porcelain was more easily broken. Therefore, early pieces of Sevres Porcelain that remain intact have become rare indeed.

Sevres Porcelain may have indeed given the makers of Meissen and Dresden a run for their money by the end of the 18th Century but for the French Revolution. By 1800, the Sevres Porcelain Works were practically out of business due to the economic devastation of the new French Republic.

About the time when Napoleon Bonaparte named himself Emperor of France (1804), a new director was named for the Sevres Porcelain Manufactory. Alexandre Brongniart, highly educated in many fields, resurrected Sevres Porcelain. Soft-paste porcelain was eliminated altogether thanks to the earlier discovery of kaolin near Limoges. For four decades until his death, Brongniart presided over monumental progress for Sevres Porcelain, catering not only to Napoleon himself, but at last to include the more financially profitable mid-priced market in the emerging middle class.

 Carved Cameo Shell

Although occasionally used in Roman cameos, the earliest prevalent use of shell for cameo carving was during the Renaissance, in the 15th and 16th centuries. Before that time, cameos were carved from hardstone. The Renaissance cameos are typically white on a grayish background and were carved from the shell of a mussel or cowry, the latter a tropical mollusk.
In the mid 18th century, explorations revealed new shell varieties. Helmet shells from the West Indies, and queen conch shells from the Bahamas and West Indies, arrived in Europe. This sparked a big increase in the number of cameos that were carved from shells. Conch shells carve very well, but their colour fades over time.
After 1850 demand for cameos grew, as they became popular souvenirs of the Grand Tour among the middle class.
Cameo subjects
Classically the designs carved onto cameo stones were either scenes of Greek or Roman mythology or portraits of rulers or important dignitaries. In history, agate portrait cameos were often gifts from royalty to their subjects. These antique cameos, some more than 2000 years old, are either displayed in museums or are in private collections.

Ormolu - (from French 'or moulu', signifying ground or pounded gold) is an 18th-century English term for applying finely ground, high-carat gold in a mercury amalgam to an object of bronze.The mercury is driven off in a kiln leaving behind a gold-coloured veneer known as 'gilt bronze'.

The manufacture of true ormolu employs a process known as mercury-gilding or fire-gilding, in which a solution of nitrate of mercury is applied to a piece of copper, brass, or bronze, followed by the application of an amalgam of gold and mercury. The item was then exposed to extreme heat until the mercury burned off and the gold remained, adhered to the metal object.

No true ormolu was produced in France after around 1830 because legislation had outlawed the use of mercury. Therefore, other techniques were used instead but nothing surpasses the original mercury-firing ormolu method for sheer beauty and richness of colour. Electroplating is the most common modern technique. Ormolu techniques are essentially the same as those used on silver, to produce silver-gilt (also known as vermeil).
