One of my kids was loading the stove last night, and some how broke the glass in the door. After doing an internet search, I'm finding a place after a Google search that sells a type of glass called Pyroceram III, show a rating of 1650 degrees. Is this the type of glass that I need? Shows a price of $70 (plus shipping) for a piece that's 11 1/8 x 9 3/4. Any help would be appreciated...
