What role does the 'radium-based ore' mentioned in the doenjang earthenware pot description play?
When you encounter an unfamiliar material like ore in the description of a cooking vessel, you become curious about its purpose. You ask this when you want to confirm why mineral components were added to the inside of the earthenware pot.

Igamono explains that radium-based ore is coated on the inside of the earthenware pot so that negative ions are continuously emitted.
The inner surface of the doenjang earthenware pot is coated with radium-based ore[1]. While seeing the word "ore" in a tableware guide may feel unfamiliar, it is a method where functional mineral powder is applied together with the glaze onto the vessel shaped from clay. Igamono explains that negative ions are continuously emitted from this ore layer[2].
It is a device that rounds out flavors. In general, natural radium-based ore has the property of releasing trace amounts of negative ions, activating the movement of water molecules. When water and paste blend, this action helps tone down the sharp saltiness of the broth and smoothly brings out the umami.
hmmm, it is a meticulous craft that does not rely solely on the intensity of the flame, but seeks to mellow the flavor of the paste through the mineral components on the vessel's inner walls.
The specific mineral types and blending ratios used in the radium-based ore glaze treatment have not yet been confirmed.
