New trick in glass making - if you're tired at the end of a 3 hour studio time, and you don't have the energy to make another vase - make a paperweight. It takes a lot less time, and it still lets you practice with a heavy glass piece.Although it's really tempting to go out and buy some color to make the paperweight more interesting - it's kind of fun just to play with the clear glass. I think I've mentionned this before, but the advice is not to start with color until you've mastered just forming clear glass - one to two years. So even though, it's relatively easy to work with color on a paperweight, I know it would only be a couple of weeks before I would start coloring vases - and then all bets are off.
And yes, the bubbles are intentional.
