Thank you @owasco!
No I don't dip the roots. Prior to rooting I use a powder based hormone sometimes, but not always. For the pothos vine I didn't use anything.
I accidently broke a root while transplanting it too, but there are a few roots in total and I think it will still root fine from this point.
That Chihuly art is super cool. I can see the similarity you're talking about with the macros. So cool, I was mesmerized looking at some of those images.
