RE: Gold Chloride

Loris,

I do not know what's in the Tetenal toner. I did not like the idea by using
the solution straight and pouring it back (or storing it seperatly). So I
tried it diluted, and it worked quite nice (gold toning on VDB works swift,
you'll see a colour change quite fast, and if not: your toner is dead). But
when I tried using the used, diluted toner again a couple of weeks later it
was dead. The stock is still ok, even after about 7 years!

Good luck,

Cor

Ps (if I were you I would not make a large stock of gold toner, just make
the amount of the citric acid gold toner you think you ned (that's ofcourse
hard..;-)..), and use it 1:5 or 1:10 diluted, single-shot, 100ml can be
easily used for a 8*10 in a flat-bottom tray)
