Vintage petal-rim cake plate, kiln unknown

This is a vintage flower-rimmed cake plate.

Based on the texture of the back of the plate and its substantial weight, I believe it is stoneware.

The elegant rim adds to the flat plate area, creating a calm and lovely atmosphere.

How about using it to arrange cutlery, or as an accessory tray, a candle tray, or a key tray by your entryway?

Condition: There are protrusions from manufacturing and some dirt on the back, but it is otherwise in beautiful condition.
Size: 38.5cm x 16cm x 2.5cm
