I have a fairly nice dining room table that I don't have a need for sitting in the garage currently. The base is made of a steel frame in a black finish and the top is just a 3/4" thick slab of glass. During the summer, I left everything in the garage thinking that the heat wouldn't be a problem. However, I'm curious if the table will sustain any damage in the cold temperatures of winter. The garage is enclosed so it's not like it will get wet or anything. But the temp. can drop to below 20 degrees Farenheit. Do I need to be worried about the glass cracking or the base rusting? I can move it into the house but it would be an eyesore due to its size. Thanks everyone.
