I believe when the material ( pyrex) reaches a temp of 700C it begins to melt 
and thus giving off toxicity. Have a look. I personally don’t feel one should 
be alarmed by this because nothing on the stove in my experience has ever 
reached such temperatures. Not even in the oven.
Hi Ernie.  Yah -- that doesn't concern me.  Although my husband managed to 
explode an Anchor-Hocking glass baking dish by using it on the stove top!  I'll 
appreciate the Ebay info if you find it.      MA
