Process for de-stamping metals in a bath of molten hydroxides, characterized in that it has a metal container equipped with heating elements, an alkali metal hydroxide with or without the addition of other compounds that, due to the rise in temperature, enter the liquid state that remains between 400 and 600ºc at which time the objects to be treated are totally submerged in the liquid mass for no more than fifteen minutes until the glassy layer softens sufficiently to be detached by mechanical means, or is completely detached inside the bath.
