While cooking in my gas GE oven, a Pyrex dish shattered. Some of the dish fragments fell into the bottom of the oven, beneath the bottom cover that is bolted down, landing next to the gas burners. Do I need to remove the glass? If I do not, will it ruin it the oven or be dangerous? The bolts are hexagon shaped and do not seem removable to access underneath the bottom cover. I'm unsure of how to proceed.
