sparkles in the secondary burn??

Never seen this before. like the aroura borealis. External temp of stove was just under 200 and I was starting to close the bypas to trap some heat in there and get the temp up. I noticed a strong secondary burnrolling across the ceiling of the stove and then I noticed come crazy burning dots in the burn. Some were sparkly and some were dark orange and turning bright blue. the load was mostly oak with one piece of gum. Anyone ever seen anything like that??? I wanted to take a picture but my wife had the digital camera. my cellphone cam didn't do it justice.

yep, common this time of year.

Ho Ho Ho

I have been trying to logically figure it out and the only thing I can figure is that before I got home from work, the kid put a lone piece of wood on the dieing coals and closed the door without giving it enough air, so it smoldered for a while. Maybe some smoke deposited on the inside surface of the stove and when I loaded it back up got things burning again, the heat and combustion gas activity inside the stove dislodged some of the deposit particles and they fell into the secondary burn cloud and "burned up on reentry".

I really wish I could have photographed it. it was COOL.
