A workpiece and a method for making a workpiece are disclosed. In an embodiment, the method includes providing a blank, applying a marking to the blank in places and heating the blank with the marking to a deformation temperature. The method further includes deforming the blank to form the workpiece and cooling the workpiece, wherein deforming is a hot forming, wherein the marking remains at the workpiece at least until after deforming and cooling, and is not destroyed by deforming, and wherein the marking has a difference in the degree of reflection and/or a difference in the degree of reflectance and/or a difference in albedo of at least 15 percentage points in at least part of the near ultraviolet, visible and/or near infrared spectral range both with respect to the blank and with respect to the workpiece. |
