Dean, I agree with Tom and by (my own) extension: What did yo have to dink the night before ? Seriously, its an intersting phenomena eh? We see it in burning different kind of briqettes too, usually at near end of burn and ususally down in the lower end of the center core. Am all ears here, as I have never tried to parse it out to particular blend or stove type … Richard Legacyfound.org

I've been noticing a shift from blue flames above the burning bio-char in a TLUD to purple flames nearer the end of the burn when the bottom of the pile is glowing bright orange. I suppose that the blue flame is caused by burning CO but I wonder why the purple forms after the blue? The blue self sustaining flame doesn't heat the water in the pot as well as the purple flame phase although the pile of bio-char is fully ignited at that time and may account for the more rapid rise in water temperature. Any ideas?
