How do you report a new material's properties so other labs can reproduce them?

I keep running into papers where the synthesis conditions or testing parameters are too vague to repeat, and I suspect my own group is sometimes guilty of this too.

We all know the obvious things to include, but the details that actually matter seem to vary by material class.

What do you consider the minimum reporting standard for a new material, and where do you draw the line between useful detail and clutter?
