Qing Dynasty Ru-ware-like Celadon Ewer with Bird Shaped

This is a celadon Ewer  in the Qing Dynasty.
The bird-shaped ewer placed on a lotus leaf has a design that connects curved lines vertically and horizontally, creating several three-dimensional curved surfaces.
A bird's face is attached to the tip of the figure, as if it were a spiral, with the eyes being a perfect circle, and the crest on the head also being curving.
There is also a swirl pattern on the top surface of the ewer, giving a sense of unity to the overall design.
During the Qing Dynasty, celadon porcelain was produced that praised and imitated the Ru kiln.
Reproducing the aesthetics of the Ru ware, the shape is uniform and thin, the tip is sharp, and the glaze is a light blue color that resembles the after-rain of the Ru ware.
This Ru-ware-like glaze has a slightly yellowish tinge, which is closer to the color of the Ru ware.
The thin container is hard and makes a high-pitched sound when tapped lightly.
The seal of the first year of Kaibao, the era name of the Northern Song Dynasty, is written on the lotus leaf.
Because the entire piece is completely glazed with glaze, there are traces of 5 support nails mark left on the back to float during firing, but they are placed at even angles and are extremely small, about 1mm in size.
The quality of the glaze, the construction of the pottery, the traces of the support nails, etc., are so high that you can easily mistake it for a piece made by Ru ware.
