Christofle paperweight
silver plated with glass
|
Christofle, the famous French silversmith, purveyor of emperors, kings, sultans, parliaments, embassies, ministries, luxury ocean liners, the Orient Express and Air France’s Concorde, was founded by Charles Christofle, in 1830, in Paris.
Interestingly enough, Christofle’s history of silversmithing is intricately linked to patented innovations that the company both purchased and filed. Trained as a goldsmith jewelry maker, Charles Christofle filed hallmarks for both master-jewelry in 1830, and silversmithing in 1845. The company he founded purchased electroplating patents enabling both gold and silver plating of objects on an industrial level. Thus, the firm transitioned from jewelry-making to gold and silversmithing of objects both small and monumental, while still retaining the jewelry activity.
During the course of the 20th century the company filed its own patents covering various sorts of serving utensils and improvements thereof, storage for silverware, silver polishing processes, various fabrication and plating processes. And most recently, in the year 2000, a nanotechnology applied to solid silver or silver plated objects, in view of delaying tarnishing or oxidation of silver. Thus, Christofle continues to innovate, having fairly recently provided a more permanent solution to all the prior art of silver polishing.
Finally, the company also has a tradition of working in partnership with famous designers such as Ora-Ito and Andrée Putman, in the most recent years.
