History : who has never heard of the "bleu charrette" ? Behind this mystical name lies a simple explanation.
Formerly cart drivers painted their carts with some prussian blue and baryta sulphate. This one had the particularity of repelling insects. Interesting, but if this formula is not great for small animals, is it safe for us?
In our approach of "without danger / without polluting, we did not recover the recipe of our ancestors. Some people say with conviction that this beautiful painting was simply colored with pastel "Isatis Tinctoria". Perfect, this idea seduces us more, but will we know how to talk to plants, we, specialists in minerals ?
And who cares ? We do not drive carts any more and nobody is likely to be pursued by a mosquito in need of blood, right ?
In this case, here is our bleu charrette revisited, closer to its original color, or at least... It is believed.
