Bronze singing bowl

I grabbed this last weekend. Looking at the shape and the resonance of it, I would guess that it's a singing bowl. I'm not sure of the age but reckon it was made using traditional casting methods looking at the pattern on the base.

 

I've never seen a foot on a singing bowl...it may ring an' resonate well, but to sing it must respond to rim-stroking.
Are there any marks, other than the circular lozenge on the base?

 

far as I know , singing bowls , have no base....and are always round at the bottom,
...

 

Okay thank you. Thats that theory in the bin. Second option was a water bowl of religious background. Hindu perhaps.

No intentional marks on it. Just the odd ding here and there

 

It is quite thick. Its 13 cm across and weighs 875grams.

 

Could be. Hoping mine has a little more age than that and think its bronze
