I have a cast iron stove that has been stored in an unheated building. Our low temps. have been around 15 degrees for the past week. I want to move the stove into my home this week. Is Cast Iron more breakable when so cold? For example, could the legs, or other parts, snap off easier when the metal is so cold? Should I wait until we have a 30 degree warm spell later this week? Any thoughts or precautions? Thanks.
