So what happened? My friend Vicki says that someone told her today
that newspaper is now made from recycled paper that has metal in it.
That could explain it, I guess.



More than likely, it was the ink.

Books get printer with a linseed oil based ink that gets dry, usually with
an additional heating step.

Newspaper ink, because of high speed printing requirements and little
expectation of longevity, are printed with petro or soy based inks that
never dry but get absorbed by the paper.

The oil can get a lot hotter in the microwave than water, certainly higher
than 451f. Add in carbon black and it is a recipe for disaster.
