In 1906, Boch Frères hired a new artistic director, Charles Catteau. Under the direction of Catteau, the firm began to produce pieces that adopted an ovoid shape  for most of the art ware vases that allowed the use of widely varied decoration. Catteau introduced decorative  influences from Japan, from modern art (such as cubism), and various African traditional elements. The fusion of attractive shapes with new combinations of  images and styles became a signature style for firm of Boch Frères Kéramis.

Denbac Pottery Vierzon, France (1921-1952) René Denert began producing his first commercial pieces in his own artisanal workshop in 1908, and licensed his business in 1909. He produced his first pieces under his own name in this business, run with his wife as a family enterprise. Denert was a true artist himself, and his circle of friends included such artists as Dalou and the architect Karcher.

Denert was joined by R.L. Balichon in 1921, and began to produce a line of commercial pottery ware. Denbac is a contraction of the name of the enterprise Denert & Balichon. This company, located in Vierzon, France, sought a name more easily marked on pieces, thus Denbac became the name these pieces were marked with after 1921. Known as a manufacturer of 'grès flammés'. ('grès' due to the color of the clay which is gray, and 'flammés' for the pattern of the glazes)

This manufactory used artisanal methods for producing their wares, and the distinctive micro-crystalline glazes were a specialty and hallmark. These glazes have a distinctive appearance and feel buttery soft and velvety to the touch and have a subtle range and gradation of color that is much appreciated by collectors and connoisseurs of fine art pottery. Denert was the creator of the more than 660 different models of pottery that were available from the catalog later offered by Denert and Balichon. The only Denbac pieces designed and sculpted by others at the factory were the sculpted figures of personage and animals. Marie Calvet and others sculpted these figures, including the specialty liqeur bottles, such as the 'Monk' series. Denert & Balichon was known as the premier manufacturer of artistic grey-wares.

The first ovens used for firing the pottery were of the square 'Sèvres' type. These ovens lacked the ability to reach and maintain the temperatures needed to fire the enamel glazes used by Denert. The next three ovens tried, constructed between 1918 and 1921, were round and measured 15 meters high and 6 meters in diameter. The interiors of these new type of ovens were separated into different 'areas', allowing the firing to be done with different strength of flames for the different enamels. The temperature of 1380 degrees Celsius was reached by the end of the firing after 18 to 20 hours in the different chambers of the ovens. Each of the new ovens had its own idiosyncrasies, and required the expertise of true artisans to take advantage of each in the choice of placement in the oven to obtain optimal results for each of the different colors utilized. The fires were fed by charcoal from the basin of Blanzy, carried to the factory by the Canal du Berry.

Denbac wares were exported to England and Switzerland, and sold in the grand stores of Paris such as Le Printemps and the Galeries Lafayette. A series of bottles was designed for special clients with needs for their premium liqueurs.

The factory ceased production during World War II (1939 - 1945). Opening for a few more years after the war, the company completely ceased producing wares in 1952.
