Yellow Glazed Earthenware Bowl , Asian?

I got it from the local antique mall. It was advertised as Rockville. To me it looked like Chinese or something. But cannot find anything similar. The age signs look natural rather than faked but I could be wrong.
Any suggestions on origin and age?
Thanks

 

I would guess student piece circa 1970

The base doesn't really show the dirt that it should in such a texture

The repair before firing wouldn't likely come from any pottery maker of name

 

Hi,
Thanks for the suggestion.
What do you mean there was a repair before firing?

 

I think I found something. Could be Islamic. Possibly from Iran, Pakistan, Afghanistan or other country in the region.

Some examples.

I am not seeing any significant dirt on any of them. But no idea how old could be the one that I have.
