Does the sudden temperature change (shock) have any adverse effects on the metal? I imagine on the atomic level, something must be "not good" for it to go from maybe 150 or 160 deg (more?) all the way down to 45 or so degrees...
Or am I too scarred by the time I drank ice water out of a cup then immediately washed it under really hot water?</td></tr></table><span id='postcolor'>
same thing happened to me. took a glass out of the dishwasher (it was still hot) and put ice water in it to drink...the glass totally cracked. that's glass though, i wouldn't think it would be bad for your car....unless you have a glass car. <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/biggrin.gif" border="0" valign="absmiddle" alt=''>
