Interesting, Freddy. Since you personally own about 2% of the known supply of Superior coal
, I assume you're burning Superior in your handfired. Of the 4 hard coal types I've burned so far, Superior was the only
one that showed any sort of output from the chimney (and this was only for 5-10 minutes after loading--after that all was clear). It looked like a white smoke that dissipated quickly and might be mistaken for steam--in my judgment it may have contained some steam, but wasn't just steam. In other words, it looked to me much like what you show coming from your chimney. In any event, it wasn't a large amount and not bothersome, but it's interesting nonetheless.
