Um, exactly what chemicals were around in medieval times?

Ancient wood stains may also have VOCs, but maybe that's a stretch ;) BCL



Guest Comment Thu, Aug 21, 2008, 11:21 am CDT VOCs have been around for as long as there has been life on earth (and even before). Only liberal ecoterrorist fools think that "chemicals" were only invented in modern times by evil scientists. The gold acts as a a catylist to accelerate the normal breakdown of the chemicals. No big news here, as that is what would be expected of any noble metal.

Well, it's almost as obnoxious as a story posted above this that's about "organic" pesticides. Like chemical pesticides produced by other plants are any less dangerous than human made ones.

Guest Comment Fri, Aug 22, 2008, 11:44 pm CDT When rudimentary things such as makeup as far back as Egypt had things like mercury and white lead in them (without knowing), things such as stains or glues in the Middle Ages would doubtless have some kind of complicated chemicals or some compounds, even if completely misunderstood, in them.
