Tiny 4 1/2 " Celadon Vase With Lotus Design / Unknown Maker and Age

This little vase came from Savers this morning. It's 4 1/2" tall with an embossed lotus and leaf design. When I removed their price sticker there was some more residue and under that were these tiny faint little blue marks. I checked Gothborg's site but I didn't see anything. I have a few pieces of this type of porcelain and it's usually modern Chinese or Korean and almost never marked. So this intrigues me. Why mark such a tiny piece ? Maybe common and modern.... maybe not. Still pretty and a bit of a mystery as to it's origin. -Mike-
