HELP NEEDED TO IDENTIFY THIS RED DISH / BOWL ?

by Stewart

Hello Peter,
I was hoping you might be able to offer some info on this piece as I do not know how to classify it, since it seems to have features that were present in the early & also later period red glazed wares.

I have scrubbed the bowl with acetone & with oxalic acid.
Whatever remains seems to be original, including the burnt orange areas to the biscuit fringes.

Could it be a copper red glaze or an iron based glaze
on a rather thickly potted dish/bowl ?
Any suggestions as to a period & or place of production ?
Also, more importantly, could it be Chinese ?

The bowl measures about 234 mm.s in diameter & is about 41 mm.s tall.
The porcelain on the base & foot rim is unglazed & has a pale buff colour.
The foot rim has been trimmed,chamfered on both edges.
There are raised ribs in a spiral design to the outside & a reserved biscuit decoration of a carved dragon to the interior.

The red overglaze, has an orange peel texture resulting from scattered, mixed sized & spaced bubbles in the red glaze near the surface. The glaze also is very glossy & under magnification appears to be fluid.

There are large crazing lines all over the red glaze.
The bowl also has scatches that would appear to be consistent with use.
The bowl is heavy for it's size & is slightly warped.
The bowl has darker areas of red spots, which under magnification,shows that each darker red spot has it's own round curly ripple, showing faintly on the surface.
There are also paler pinky flames where the glaze is thinnest on the white underglaze.
The white underglaze also looks much thicker than the red glaze...this is most evident when viewing the glazes near the edge of the biscuit dragon.

I hope these details make sense to you, as I have tried my best to explain what I see.
warm regards & much appreciation,
Stewart.
