antique 1800s vintage flow blue china pewter trivet, tea kettle stand for tea table

Beautiful very old flow blue china tea pot stand, a pewter framed trivet about 6 1/2" in diameter. This doesn't seem to be marked at all that we could find.

It's very 'flowed' with a barely visible pattern under all the color. But there's no chips, cracks or staining from use, it's a lovely old thing in very good condition.
