I was sitting in an auto shop getting a vehicle looked at and saw this show about shattering glass bakeware.  I thought it was informative and interesting and placed a quick link to a program the ‘Early Show’ did about the issue.  >Shattering Glass Bakeware.

Apparently, you should not quickly change temperature with the glass cookware.  You know, like taking it out of the oven; getting the food out then quickly putting it in the sink under cool water.

The video might be helpful in learning what NOT to do if you use glass cookware.
