PETER COULD YOU IDENTIFY THIS GREEN GLAZED POT?

by Andrew

Hello again Peter,
thanks again for your comments regarding Sancai ware....I really need to learn about oriental shapes, sounds like a huge amount of knowledge & time needed to acquire information.
Being elderly, I don't think I'll catch up to where I'd like to be, but it's an interesting journey for me.

Peter, I have this pot/jar has incised ribbing & probably moulded, 2 fish chasing each other pattern....similar to fish you see on Longquan celadon fish plates.

Is it an earlier type of celadon?
or is it a Han dynasty type green glaze?
finally could this be from a shipwreck find...Thailand?

I really am guessing here.

Any info as to origin, age or glaze class would be most valuable as always.
again sincerely,
Andrew.
