AHHH I'm in love with soft glass marbles! So much easier to work silver glass with limited oxygen. Also can get decent sizes with only one concentrator. With boro I'd have two concentrators but seemed to take forever to get a decent size marble made. I just fixed this marble yesterday, I was surprised that this size marble could be fixed since it was soft glass but I had no problem reheating it in the flame. Anywho here is the marble.
