I once bought this toner from Photographer's Formulary.
This toner consists of Stock Solution A and B. To prepare part A
you have to prepare solution 1 and 2 first than mix them together
to get part A:
<bold>Solution 1
</bold> <bold><italic> 1 Liter 2 Liter 4 Liter
</italic></bold>water 125°F 750ml 1500ml 3000ml
sodium thiosulfate, anhydrous 152gr 305gr 611gr
potassium persulfate 30gr 60gr 120gr
water to make 1000ml 2000ml 4000ml
<bold>Solution 2
</bold>
water 68°F 16ml 32ml 64ml
silver nitrate 1.3gr 2.6gr 5.2gr
sodium chloride 1.3gr 2.6gr 5.2gr
<bold>Combining Solutions 1 and 2 to get Stock Solution A
</bold>
Both solutions must be at 68°F. Stir solution 2 vigorously to disperse
the solid
throughout the solution, than pour all of Solution 2 into Solution 1. Mix
thoroughly.
<bold>Stock Solution B
</bold>
water 68°F 62.5ml 125ml 250ml
gold chloride 0.25gr 0.5gr 1.0gr
<bold>Mixing the Working Solution
</bold>
To prepare the working solution one-half of Stock Solution B is added to
Stock
Solution A, the rest of part B is used as a replenisher
<bold>Replenishment
</bold>
About 4ml of Solution B should be added to the working solution after
fifty 8-by-10 prints
have toned. Exact measurements cannot be given
