No, I did not send a sample. I called PF and asked them what to do, and I was instructed to send an email describing what problems I was having with the product.
I suggest that you write and tell them the problem is not solved and ask to send a sample. Ammonium Thiosulfate solid is known to be sensitive to excess heat, and if it were to have been overheated during shipping it could have sulfurized. That is the technical term for this type of problem. The byproducts include what you see, an odor of rotten eggs, and sometimes black deposits due to interaction with other items present, such as metal cans or plastics.
You can generate this effect in the lab by taking pure, clear ammonium hypo solution and adding concentrated sulfuric acid to it. An off-white scum forms instantly along with this odor. The odor is optional depending on the degree and rate of decomposition, since the gas is volatile. A slow decomposition will allow the odor to dissipate from the solid.

Yes, there is an odor of rotten eggs. I balk at writing PF, hat in hand, begging them to allow me to send them a sample. But since I asked for suggestions, and since I respect you and your advice, I will write PF. Thank you for your suggestion.
Bud is a very open and approachable person and so is Sherry who probably took your order. They will bend over backwards to help you. I know, as I have seen their efforts to satisfy the very few complaints they do get. You have gotten to them in the midst of their workshop season and this does slow down responses.
However, you are not going to them hat in hand. You are a customer who paid for a product, and Bud is a customer who paid for shipping it to you and paid for good, pure product. Somewhere, something may have gone awry and neither of you should feel bad. This happens. People want ammonium thiosulfate powder, and it is a difficult material to make pure, to ship and to store. This is why the bulk of this chemical world wide is a 60% solution instead of the powder.
This fact is unfortunate as it adds to the cost to ship water, but it reduces problems. I have 3 gallon jugs of the 60% here that are up to 3 years old and are still good. The powder would last that long, at least, but the liquid concentrate will keep on going, I am sure. Ask them and do not feel bad.
