Mixing Nelson Gold Toner
Recently, I made up 2 liters of Nelson Gold Toner. I followed the instructions carefully. However, the sediment that formed after the addition of the Gold Chloride which the instructions said may continue for several days to a week never stopped. Even after more that 2 weeks a very yellowish sediment continued to settle and cling to the sides and bottom of the glass jug.
What caused this? Also, the milkiness that formed during the mixing of the Ammonium Persulfate and the Hypo turned into a yellowish sediment. The water I used was at 125deg F, was this temperature too high. Does this sediment need to be filtered out before adding the Gold Chloride solution?
