Hi everyone-I recently had my newly installed glass backsplash crack on me while using a griddle on my stove. My contractor said that he has contacted many manufacturers and this is the nature of the beast. I'm not sure what to think. The glass is heat resistant but not tempered-he said tempered glass could shatter if there were issues. What is your experience? Do I replace the glass or put up a stainless steel guard a foot up from the stove?
