Safety first
I just read an article on-line about glass baking dishes shattering and even causing injuries. This includes brand name glass dishes too. It seems the manufacturers changed the formula for the glass baking dishes back in the 1980's. It made them more likely to break even while just sitting in the oven, at the table or on the counter. No hard bumps or knocks are needed to cause the breakage. The manufacturers have included directions for using these dishes safely but even following the directions the dishes can still shatter. Vintage glass baking dishes don't have these same problems. So be safe while cooking with them. I don't think I'll be using any glass baking dishes unless I'm certain they are older than 40 or so years.
