I'm also considering how to make bases for tables, though will use wood not glass. One of my teachers just made a couple of furniture pieces that are gorgeous. You might look at the work of Austin Coudriet or Kelsie Rudolph (both are on instagram). Kelsie makes handbuilt furniture and Coudriet large-scale sculpture and furniture. He has great tips about drying and firing large work. Rather than using steel rod I think you might want to consider building internal support structure (out of clay) that prevents slumping and provides strength. Both these artists show useful examples of this construction and it's been helpful to me.
