No worries about time wasting. Good news: I'd bet you found your problem!
Also, before you cook up another batch with 100% silver nitrate, you might read the last couple of posts on page 3 of the thread "Substituting chrome alum with glyoxal."

I think you'll have a lot of fun from this point forward. One thing you might consider. You can cut your recipe exactly in half (just the ingredients, not the times and temperatures.) That way you'll go through a lot less silver nitrate as you are learning. Looking forward to hearing how things are going. d
