This vase is a rare Ru Kiln piece from the Song Dynasty, boasting a dignified and elegant form. The glaze is sky blue, like "the sky is blue and the clouds are broken after the rain", and the glaze surface naturally cracks, forming rust-like ice cracks, which is ancient and vicissitudes of life. The body of the bottle is made of gilding technique, the dragon pattern is vigorous and majestic, the scales and claws are distinct, and the gold color is dazzling, which contrasts brilliantly with the green glaze. The double phoenix ears have a smart shape and smooth lines, showing the royal charm.
Ru Kiln firing was extremely difficult, and this vase, a unique combination of glaze color, decorative pattern, and craftsmanship, is a rare find. It possesses both artistic and historical value, and is considered a pinnacle of Song Dynasty porcelain.
