Interesting thought. I'm going to try the clock-wise spinning mode. Will let you know how it worked for me.

I also use Karen B's approach. using the same body clay to make your slip makes a best match, not that the other wont work, but this is the perfect combo.

You don't need to glaze over the glass, the glaze is a form of glass itself, so the options you have is to glaze the pieces and then put the glass over the glazed piece or, leave the piece un-glazed and put the glass over the raw bisque. You will find what you like best through experimentation, make small projects to start and go from there. One recommendation I can make is never mix different glasses. Hope you get what you are looking for. Best.
