I've only used gold following sepia, but could get 15-20 8x10's out of it at room temperature. Heating it extended it for another 10-20 prints. This was on conventional silver prints, so I don't know the effect the heating would have on salt prints. It may be worth trying, though.
I take it you mean 3 Litres of gold toner. 3 Litres of 10% gold chloride would need 300 grams of solid gold chloride which at current Photographers Formulary prices will cost over $20,000. :eek:

was worth only $18.00 and ounce, or $9.00 apiece for the two of us - hardly worth it! But at today's
prices, different story. But gold is valuable, so I too use gold toner heated, and only the min amt
necessary to actually do the job in solution. I bought an extra bottle last yr in anticipation of the
spike in gold pricing, but notice that gold chloride itself has barely risen in price. No need to raid
And Drew even had a photo taken:whistling::

Just out of interest how did you make a 10% gold toner solution and more importantly how does it perform?
If this is what you are asking...
I pounded down a ring and a few other pieces of gold, flat, from the wifes first husband. (she enjoyed it too)
Mixed up (outside) some Aqua Regia, boiled it, dropped in the gold. Let it go for a couple of days. Added a bit of acid when needed.
Let it sit for a week to dry, then weighed the result and mixed with distilled water.
Once in solution, I make a 1% working solution. 20cc's of gold and 200 grams of ammonium thiocyanate add to 2 liters of distilled water. heat to 80f and use until I get tired of waiting for it to tone something.
There are a lot of formulas for gold toners. Some have a short life even in glass bottles, while others have very long lives. I use thiocyanate toners, for which I have seven formulas, for salt and kallitype prints. My cost is very low and toning consistent because i use toners as single shot. I mix a liter of the two stock solutions of my favorite toner. 5 ml of each stock solution are diluted to a liter. I use 20 ml of this diluted toner for an 8x10 print and then discard it. Some papers soak up more of every solution than do others partly due to paper weight, and partly due to sizing.
A little research into gold toners will quickly reveal all of the formulas I have collected through research, and make obvious the one I prefer.
