Vintage/Antique Pottery Bowl~Beautiful Color, Interesting Application~Unsigned

Hello All!
I've been watching this bowl for some time but thought it was a new piece and noticed it wasn't marked,( also a little pricey ),.....so I didn't buy it.
Today I walked into the shop and saw it sitting on a shelf and still felt attracted to it.
I thought it deserved another look.
From the wear on the bottom it appears to be quite old,
I love the colors and the way that the glazes are isolated from each other by the flat black outline, and also the transparent and opaque areas of the green glaze,........over all I was pretty impressed and had to have it.
( it reminds me a wee bit of a Paul Revere trivet that I picked up a couple of years ago )
Does this look familiar to anyone?, any quesses who could've made it?
Thanks for giving it some thought,
Happy Week-end,
Tony
