Watching the fire tonight and I see many different colors to the flames. I have in the stove now a good bed of coals from maple and ash. Threw in two splits of birch and one good size round of oak. With that said the stove is reading 600F. But what about the colors of the flames? I see yellow and oranges everywhere but I also see blue. Almost like a blowtorch blue. Is the blue hotter than the rest or just more concentrated? Interesting to think about and what is the temp of the blue flame typically?
