You would have to have a generous lip or the glass will slip in. Cook the colors you want so as to maximize the drop, but not let it touch the floor. Cool and smash. Another option is to fuse big circles of the target colors on a shelf that has deliberately been made concave in the center. You would be deliberately trying to get the bubbles that most of us fear. Get 'em as big and glorious as you can, and as with the drop out you should have some pretty thin glass that is great for sharding. Granted this is low production technology, but might tide you over till Spectrum starts blowing bubbles.
