Ok, this is far from perfect in many ways but I thought I would document my first ever attempt to make a marble. It's borosilicate glass and I did a very simple frit implosion with several layers of green amber purple and clear frit because I wanted a dense core. The total size is just a hair over an inch diameter.

I need to figure out what folks are setting their MIBs on in the kiln. I got a little kiln brick dust making a dull spot on one side - it didn't flatten the marble but it did make the surface dull almost scuffed so that's not kewl. Also I have to pay more attention to my final punte and divot clean up. I think I'll make a pair of those marble tongs that Drew Fritts has on his web site. I am sure I have a wire hanger around here somewhere.....
