#164169 - OP said "all solid material"

What is Wiedemann-Franz law for?

Too narrow quote. The sentence is only meaningfull if shown with the previous sentence, i.e.

Now you have to tell me why you think the OP specifically intended to limit himself to materials where there is a correlation between electrical and thermal conductivity? For now, such a specialisation has not been established.

In short: I can't see that it has been clearly established that the OP only intends to look at materials with this property. It may be so, but I would prefer to see it explicitly written before limiting the view.

Yes, I did see your question in the first post. I just wanted to know why you wanted to limit the search so quickly. And the OP did follow up with the header "all solid material"

The question here is not what specific methods there are to measure specific properties when limited to a specific subset of materials. The first question is what exactly the OP want to do. What range of materials. Really important what size the samples have? Electrical conductivity as function of temperature? ...

In the end, I don't really know much about what the OP want. And most probably nobody else either. But premature specialization can be problematic.
