The year 1738 saw the beginning of Vincennes Porcelain.  It was founded with the support of Louis XV and Madame de Pompadour to compete with the manufacturers of Chantilly and Meissen porcelain.  It’s mission was to create works of art using artisanal techniques.  This included both the productio/reproduction of older works as well as the contemporary creations of living artists.

   In 1756, the factory was moved to Sevres where it became the “Royal Porcelain Manufactory.”  The factory focused on producing luxury porcelain for the royal family and the aristocracy.  The factory also manufactured items as needed by the state as well as items for commercial sale.  It was also charged with the research and development of technological aspects regarding  porcelain production.  As part of this new artistic ideas came into play as to decorative styles and colourings.  Artists of the time which included Francois Boucher and the neoclassical sculptor Augustin Pajou became involved with the artistic direction of the business. 
The factory continued to produce porcelain although the French Revolution put a great strain on its finances.  It lost both royal patronage as well as most of it’s clientele.  The factory recovered slowly throughout the 19th century and by the end of the century new shapes and form, asymmetricality inspired by nature and the Art Nouveau movement were influential in it’s creations.
  The Sevres Manufactry produced some of the most exquisitely designed and decorated porcelain ever made including dinner services, ornamental figurines and extravagantly decorated vases embellished with ornate relief designs.

 Both pieces shown have the ‘double Louis’ reversed and intertwined ‘L’ mark.  The space created by the intertwining was left vacant in the years 1751 to 1753.  It is possible that these two pieces are forgeries since the Vincennes/Sevres mark has often been reproduced for finàncial gain.  Even so, the two pieces are very finely produced and painted in the style of the time.  I have not found other images of the two pieces.  Both are slightly damaged and remain unrepaired.  Should one repair artworks like these or not.  I’m not sure.
