Florence, January 7 - A court in Florence declared the historic ceramic maker Richard Ginori bankrupt Monday, sources said, ending a lengthy struggle and eliminating more than 300 jobs. The ruling was filed by court judges Monday morning, which apparently ends efforts to sell the company - founded in 1735 - to a buyer from the United States. Last fall, the Tuscan ceramics producer sought court assistance as the company began to go through its liquidation process. The company had stopped manufacturing at the end of July, laying off 337 employees. The regional government said at the time that it hoped to find another business with plans for reinvestment to revitalize the ceramics producer. Late last year, the company thought it found a solution and said it had a purchase offer from a consortium led by Lenox Corp., of the US. The Florence court appointed Andrea Spignoli as administrator of Richard Ginori during the liquidation process.
