<x-rich>Hi Sam

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

Best
