A large, hand made antique French copper diamond shaped turbotière fish kettle, dating to the late 18th or early 19th century. Complete with its original perforated tin grille insert. At 53cm long, 46cm wide and weighing 7.06kg, this is a substantial professional-grade example — and complete specimens of this size and age are exceptionally uncommon. Handmade dovetail joints are visible on the underside and underneath one of the handles. The handles are copper too, with handmade copper rivets - it's a truly beautiful piece of workmanship.

Designed for poaching whole flatfish — turbot (the "king of fish") — in a court-bouillon. The chamfered rectangular form mirrors the diamond shape of a turbot, and the perforated grille allowed the fish to be lifted without breaking the flesh. There would not have been a lid, and there is no lip to accommodate one.

Measures 62cm long handle to handle and 53cm without. Max width is 46cm and height is 13cm. The total weight is 7.06kg, with the strainer weighing 2.3kg and the copper pan 4.76kg.
