Cracked, Crackle, Krackle or Shatter Top Glass, whatever you may wish to call it, has a beautiful effect. Our Crackle glass is made by laminating three pieces of 1/4" glass with the middle piece tempered and then broken. That is why Crackle Glass is just over 3/4" thick. For an even more interesting look, low iron glass may be used. Please see our Portfolio for a picture.
