Turquoise ceramic plate is an antique Email Ombrant piece

This turquoise ceramic plate is an antique Email Ombrant piece manufactured by the Rubelles factory in France during the mid-19th century (circa 1836–1858). 

    •    It features a unique technique where the scene is molded in low relief (intaglio) and then flooded with a translucent colored glaze, creating shades based on the depth of the design. 

    •    The plate typically depicts scenic motifs, such as landscapes or orientalist scenes, under the green or turquoise glaze. 

    •    These pieces are highly collectible and often marked with impressed stamps on the back.
