To use this vintage jug, you can fill it with fresh flowers to create a beautiful centerpiece on your dining table or place it on a sideboard as a decorative item. When handling the jug, be gentle as it's an antique and might be fragile. To clean it, simply use a soft, dry cloth to dust it regularly. Avoid using harsh chemicals or abrasive materials, as they could damage the glaze. Store it in a safe place away from direct sunlight to prevent the color from fading over time.
