Be sure you use a fixer with hardner after toning.
We have always used it warm, put a stainless steel tray on a hot plate. fill with water and put another plastic tray into the water with the toner.

It will work much better with the warm tone papers than with the colder tones, especially if you are looking for a serious shift in color. It will also split tone.


Check Jonathan Bailey's web site for some examples.

I am out of town and do not have any prints with me.

Another great toner for these papers would be Hypo-Alum .
