A method and a device for optically ascertaining the mutual binding of a first and a second reactant are described. Use is made of the fact that a dipolar layer (,) having a non-linear optical behavior is formed upon a reaction between the two reactants. The formation of such a layer is ascertained by illuminating the substance with radiation (,) having one or two frequencies, and by detecting whether radiation (,) from the substance contains a component at a frequency which is twice the frequency, or a mixed term of the frequency of the radiation incident on the substance.

The recharging time for reheating the soleplate of an iron can considerably be reduced by accumulating energy from an energy supply, e.g. the mains, in a stand for the iron and by transferring this energy to the iron when the iron is attached to the stand. The iron is reheated very quickly, e.g. by exchanging cooled down liquid from the iron with hot liquid accumulated in the stand every time the iron is put back in the stand.
