Yes. If your CS has a large particle content, and overall exceeds some minimum level (something over 26 ppm), then when the large particles are converted to ionic, the ionic content can exceed the solubility of silver oxide/hydroxide, and will produce a brown sediment. If you have mostly ionic in which you already have brown suspension of the ionic precipitant, then that will be converted to 2 atom colloid, reducing the ionic content to under the solubility limit, and it all then dissolves and goes clear. Here are some examples, asuming that you end up with 67% ionic after the H2O2 is added: Lets assume that after adding H2O2 you end up with 33% particle, and 67% ionic That is quite possible since the ionic portion will be both silver oxide and silver hydroxide, so if we end up with equal amounts of each that will give 67% ionic. Start with 35 ppm 90% colloid large particles 10% ionic color brown from large particles and ionic silver precipitant, result 33% colloid small particles, 67% ionic. Ionic content goes from 90% 35 ppm = 31.5 ppm to 67% of 35 ppm = 23 ppm, and since the ionic content is now below 26 ppm it all dissolves and the particles are small, so it goes clear. Start with 42 ppm 60% ionic with colloid large particles color gold from particles only the ionic is totally dissolved (ionic is only 25 ppm). Result is 67% of 42 ppm = 28 ppm ionic, with the particles once again 2 atom in size, so it goes to brown with the ionic silver oxide/hydroxide precipitant. What this basically says is that it does not matter what the initial ionic vs particle content of the batch is, what matters is the total silver content including both the ionic and particulate, and if that amount is less than some certain amount (around 40 ppm?, then it will go clear with H2O2, and if it is more it will go cloudy and brown.
