The frost is on the pumpkin

For many years, now, as Halloween passes and the hard frosts begin, I have been worried over my glass crucibles... not the hot one filled with glass, but the retired pots decorating gardens and becoming birdbaths. Many years I have taken care to empty the water when a cold spell is upon us.

Recently, I have realized that I have never had one crack and maybe the thickness of the crucibles protect them. Have other blowers had the same experience?

Several year ago, I started insulating the surface of the water in the crucibles by floating a circle of foam wrapping (poly-ethylene?). This delays the top of the water from freezing. This is an easy solution to the potential problem, but is it needed at all?
