Hey, thanks for the kind words! I totally understand how challenging it is to find answers to all these questions, and we are redoing our search engine right now, so it's harder than usual to find the articles, for people who don't already know where they are. Plus, we love helping people who are new or relatively new to kiln-glass--there is a lot to learn, and we understand and respect the effort required to master this material!
Re your glass, I don't think the cranberry will turn brown, but if it is already more or less the color you want (through extra heat work at the factory) you can just fire it as if it were a more stable glass, like cobalt. If you suspect that the cranberry has not struck, you could try doing that soak. I don't think it will turn brown. But you should cut off a small piece that includes pink (or lavender, because the 1311 tends to look lavender or bluish before striking) and test it using your planned cycle before you make your finished piece.
