That's a real problem. I think you need to talk to Kevin, and firmly ask them to replace your chemicals, paper, and the time you wasted on their mistake. They need to understand how important it is that they get those starter kits right, because a person who tries a buggered starter kit may never continue on with pt/pd.

Look at the color of the solution in the dropper. If it is a bright yellow, you have NA2, if it's a magenta-brownish, you have the normal platinum #3. That'll determine it for sure.

Mistakes do happen, so I think that you might want to give them an opportunity to make it right.

I recently discovered that the 3 months and dozens upon dozens of film tests that I had been struggling with was completely wasted, because the supplier sent me the wrong (inferior) version of the film that I was working on a developer formula for. 'Darn, so that explains why I couldn't get a decent curve out of the stuff'.

FWIW, most people print mostly in palladium, either 100% palladium, or 75/25. Some do print in 50/50, and few print in pure platinum. There are very few papers that will accept a pure platinum image gracefully, and the efforts to make a pure platinum image are much more difficult.

I recommend you put away the platinum for a little while, and start making some images with pure palladium. It's cheaper, so you can be a little more carefree with the printing and experimentation, and it eliminates one variable from the process for a little while. Once you have gotten competent with the process, you can start adding in the pt to the mix.
