Not saying the Sumerians made a Copper Oven exactly as the one in your image,
Yet it's fact the Sumerians alloy Copper with other chemicals/metals to create
Heat endurance/tolerance.

They created specialized Fire Brick for Kilns to create in high temperatures regular brick could not endure.

This combination technology application/knowledge. ...may preceed the Sumerian kingdom
As coming to them via other Regional who worked ores for metallurgy/weapons and possibly Fired Kilns.

It's the concept...
The shape of portable Ovens....can even be wheeled.

Mainstream/peer review will of course say Prove it...
Copper will breakdown in air or soil and only under specific circumstances endure over time,
Unless something added to the copper via alloy or chemical...cancels the erosive factors.

The Sumer/Levant evidentiary in Naqada periods Egypt indicates the portable Oven could indeed be in Egypt back then.
Something even ancient boat/Mariners who plied trade ...might bring along for fish catch and put another Shrimp on the Barbi : )
