I found the same thing… A little bit of bubble powder goes a long way but you can do some really cool things with it.  I just got some metallic bubble powder from bluedragonglass.com and it left really neat bands of metallic color around the bubbles.  I had to experiment a little bit.  I found that if you use too much it makes the glass brittle around where the powder was.
