I have obtained several large pieces of different colors of bulk glass. They are irregular shaped between the size of a baseball and softball. The pieces have sharp edges an many are covered in scratches and flaked edges.
I am using these in some yard art in which I wrap the pieces in copper rod in small sculptures. I have used the glass as is, but I am interested in trying to soften the edges and getting a polish on some of the surface. Minor imperfections are no big deal, I just don't want to crack the pieces or have them slump.
Would fire polishing be possible? I am thinking that because of different sizes and colors of the pieces the trial and error to find a working procedure would use up all all my glass. Are there basic guidelines I can follow that might work? I have done no glasswork before, but have access to a kiln. The owner of the kiln has done lots of enameling, but no work with large pieces of glass.
I would appreciate your comments. Thanks,
Barry
