Antique Asian bowl

I don't know much about this bowl only that it is antique. Could someone please help me?

I had gotten my bowls mixed up and thought I had bought this bowl, but this bowl was actually in my grandmothers curio cabinet when she passed. I believe there is something more than a regular bowl otherwise she would have had it with her dishes and not her antiques.

I know it's antique; I do not know the age though or anything else about this bowl.

Please help if you can?
