Plique-à-jour is a decorative technique used in glassmaking that creates a translucent effect, resembling stained glass. This method involves fusing glass pieces together without a backing, allowing light to pass through and illuminate the colors. The result is a vibrant, luminous appearance that enhances the beauty of the glass. Originating in France, the term translates to "letting in daylight." Artisans often use this technique in jewelry and small decorative items. The intricate process requires skill and precision, making Plique-à-jour a sought-after style among collectors and artists alike.
