Plaese it's the tow chinese CELADON Crackled vase.??
This is Korean celadon, 20th century probably. Could also be later. Marked Korean porcelain usually have the name of the artisan who made it/them added in the manner shown here. Most antique Korean porcelain was never marked.
In the 20th century some Korean potters started re-creating celadon and marked them.
Thanks Peter I had doubts between Chinese and Japanese Celadon, I never thought about Korean. Thank's
