There was a lot of good information recently about smoke color and using an offset. My question is this. I added some wood chunks to KF in the firebox. Grate temp 235 top temp about 250. Preheated the chunks on top of firebox. Was getting some blue smoke out of the firebox as we all know offsets leak. Smoke out of the chimney was white/gray. More smoke out of chimney then FB so I know it was flowing. Does the smoke cool while going through the cooking chamber causing it to go white? Hoping for nice blue but don't know if I really acheived it.
