um, i can't see how having a little residual hypophosphite is gonna cause a problem, since hypo is one of the steps on the road from red phos to phosphoric acid in the reaction process. anyway, it would maybe cause a little I2 to be lost maybe if it reacted, which i doubt it would considering how much diluted it would become (the hypo i mean).
thanks ware, i think for some reason they haven't quite cottoned onto the clear tincture. seems silly to me when it probably gives up the goods just as good as the brown tincture.
