Just threw a large heavy piece of oak in the wood stove. Within about 5 minutes, the whole house had a sickly sweet smell. Never had this happen.

It's Live Oak, and is supposed to have been split about a year ago. This is out of a cord I purchased since I couldn't split enough last spring. Guy is very trustworthy, so unless he made a mistake, I believe him about how long ago it was split. Although, it was rather heavy for a year old.

I'm not overly concerned about it. Just curious. Anyone have any idea? Wood stove is old, gaskets are in good shape, and it's been working fine.
