Is there a reason for using metol instead of dimezone-s? My understanding is
that dimezone-s is a form of phenidone. The next time I mix up xtol I'm going
to try using edta instead of the dtpa. The dtpa in the quantities I'm ever going
to use the stuff at is expensive. Of course I bought 100gm of the stuff and the recipe
I have uses 1gm per liter of stock and I've got a supply of the stuff that will
lat me for years at my current rate of use! :-)
