Possibly, but my guess is unattended candles. ................ I had a log cabin home, I let a friend stay there. When they left they forgot about the candle on the pine coffee table. When I went back to the cabin, there was the wax, melted down on a nice wax crater with no wick left. Had the cabin caught fire it would have been consumed before help arrived. It was off season and north of Ray’s and across from Bernie’s. Fire was always my greatest fear when we were there. We had a cast iron wood stove in the LR to keep it warm.
Yes, I read years ago, before Internet, that unattended candles were the major cause of house fires.............
