Here is a myth that a blog reader submitted. I can’t find anything about it. Help, anyone?
Pie Tin Fire Alarms
“I’m trying to track down information on another early “alarm” system said to detect fires sort of like a smoke alarm. The story goes that pie tins were secured to ceilings by wax. The heat from a growing fire would melt the wax, causing the tins to drop to the floor and make enough noise to awaken the residents. Securing such tins to ceilings throughout a room would have been unsightly, but the concept makes some sense. In addition, blazes caused by untended fireplaces and early wooden chimneys were a serious problem in colonial times. Do you have any research to document or debunk the use of “pie-tin fire alarms”? (Researching a third edition of my History of Alarm Security book.)”
Sounds ridiculous to me, but I cannot back that up.
