Overview
This is an authentic French glazed stoneware condiment jar or storage pot, featuring crisp debossed lettering reading 'LAB Lagny' near the base. Produced primarily for mustard, rillettes, or dairy preserves, it is finished in a warm, glossy cream-colored salt or slip glaze. These durable pots represent classic French utilitarian kitchenware that has transitioned into coveted rustic decor.
Story
Long before plastic, French grocers packed gourmet mustard into heavy stoneware crocks like this. Lagny-sur-Marne was a famed hub for food packaging and ceramics serving Paris markets.
Maker / Origin
The mark 'LAB Lagny' relates to commercial food producers and packaging potteries operating in Lagny-sur-Marne, east of Paris. Lagny had a strong tradition of industrial pottery, producing heavy stoneware (grès) vessels tailored for regional food merchants, creameries, and condiment makers.
Condition & Value
Appears to be in very good vintage condition with an intact glossy glaze, crisp lettering, and no severe cracks or rim chips visible. Excellent preservation keeps its value at the upper end of the decorative utility market.
