"Lignin-free" boxes

jan, talked with eleanore about the lignin question and she suggests
that you could verify it by using c stain (should turn bright
yellow-orange, if I recall, which I probably dont) (unfortunately other
things also turn yellow, but hell if it were easy it wouldnt be
scientific).
