I have an outdoor furniture set by Martha Stewart for Kmart. It has five chairs and the table has a lazy susan on it. I absolutely love this set. It has sat under an eave where it would not get wet(the info that came with it said that the finish would last a long time if it was not exposed to rain). Even though it has been protected from the elements it has started to rust but because I love the set so much I have been touching it up (without much success).
Yesterday morning, I heard a terrific BOOM and then another BOOM. I went outside and the glass on the table, except for the lazy susan part, had exploded and was lying in little squares under the table. We often have dinner out there with my two small sons. I shudder at what could have happened to them. No one was at home at the time but me and no one was on the patio.

I would like to know why this happened and how likely it is to happen again. I feel that kmart should replace my table and I would like to be assured of its safety.
