Is it possible to over-oxidize in the potassium permanganate when doing a retic stain? We do the Gomori's retic and the procedure here says to leave in the potassium permanganate (0.5% solution) for 5 minutes. When we left it in for only 1 minute our staining seemed to be much darker. Laurie Colbert
