I am showing in a upper northeast gallery on The ocean shore. My question Is ...Are My Glasses safe from cold weather while being display on The Gallery windows on iron frames? I am worried about cracking in extreme conditions at night when They conserve on heat...It's a pretty chilly area. I Hope I am over reacting And You can confirm I am Really being silly. I Hope I am NOT wasting anyone's time.

Hi Marie,

I don't think it's a problem. A possible exception would be if it gets VERY cold at night, and then there is bright sun in the morning that hits only a portion of the piece, leaving the other in shade. A big temperature differential within the piece could lead to cracking, but there is much less risk of this indoors, and honestly, it seldom happens outdoors either.

Here are some related threads on glass being exposed to different temperatures while on display:

I have a 1/2" cast piece that sat outside all winter last year. In Northern Utah, we always have a few weeks that get down to -10 deg F or colder at night, with daytime highs barely 0 deg F. The piece survived just fine.

It is on the North side of the house on the front porch, so, as Mary Kay suggests, it's not getting hit by direct sunlight or being exposed to rapid temp increases.
