I thought the 1st to be a Michaelangelo. So it has to just be a cobalt blue transparent base? The 4th I thought to be a Heaton with some swirl being UV lit. And the last one I had confused with a Razzle Dazzle. Ooopppps Thank you so much for clarifying and sending me your expertise!!! Lord today it's so hard trying to ID all the colors and patterns. It all seems to start running in together. I'll be sending more! 😀
