CHARLESTON, W.Va. -- The packaging for the Pyrex product shows a warning not to set the glass dish on top of a hot stove.

But it doesn't show what happens if you do.

Megan Simpson had just gotten her glass casserole dish out to start fixing dinner for company she was expecting at her Bridge Road apartment. She mistakenly put the dish on a burner she had turned on to boil eggs. Realizing the dish was on the hot burner, she bent over the stove to see if she had scorched the casserole dish.

Fortunately, she stood and turned her head away just as the glass dish shattered, propelling chunks and slivers of glass all over her, the stove and the kitchen.

"I'm lucky not to be blinded by the Pyrex," she said recently, recalling the January incident. She said she had to use pliers to remove a piece of glass impaled in her shoe.

Former food columnist and now Gazette Executive Editor Rob Byers put a hot Pyrex casserole full of gravy on a hot burner on Thanksgiving Day five years ago.

His wife, Tara Tuckwiller, wrote about the incident in their "Main Ingredient" column in the Sunday Gazette-Mail.

She and guests were seated for dinner, waiting for Byers to finish the gravy. "Then we heard what sounded like a high-powered rifle shot in the kitchen."

When she peeked into the kitchen, "Gravy was everywhere. On the stove, the floor, the walls, the ceiling, dripping from Rob's goatee. Little microdroplets of gravy hung in the air like chemical warfare. <t40>...<t$>

"We had roasted the turkey in a Pyrex baking dish -- we didn't own an actual roasting pan -- which went fine until Rob plopped the glass dish onto the stovetop to make gravy out of the pan drippings. Apparently, you can't put Pyrex on the stove. Just FYI."

That same Thanksgiving Day in 2007, an Illinois woman was baking a ham in a Pyrex baking dish at 350 degrees. When her daughter opened the oven door to baste the ham, "the dish just exploded." The women had splash burns and a child cut her foot on a piece of glass.

"I can't tell you how scary that was," Patricia Szczenia told Consumer Reports.

In a January article, the magazine reported on tests it conducted on Pyrex and on Anchor Hocking glass bakeware during its year-long investigation of the products.

Consumers Union, the publisher of the magazine, urged the Consumer Product Safety Commission to conduct a thorough study of glass bakeware "with particular attention to the differences between bakeware made of soda lime glass and of borosilicate."

Tests done by Consumer Reports found that glass dishes made of soda lime ash shattered at lower temperatures than those manufactured in Europe, which uses the more expensive borosilicate glass.

The website for Pyrex says the glass bakeware has been made using the same soda lime composition and heat-strengthening process for more than 60 years, first by Corning and then by current owner World Kitchen, and at the same plant in Pennsylvania.
