Ash in the stove turning blue

[Cadillac Nick]

Question for everyone, has anyone ever had small sections of ash in their stove turn a bluish green (almost like corroded copper). It seems to only happen on cold nights when I am burning black locust, I haven't noticed it with other woods. I also only notice it in the clinkers that I have in the front of the stove. I was just talking about it with the wife because she noticed it also in the ash bucket.

Thanks, Nick

Just noticed it the other night. Figured it was a mix of blue flames off the coals and yellow off unburnt woood? Been burning elm too.

I have also been burning some elm.

It probably has something to do with the type of wood you're burning. I've been burning Juniper and my ash is mostly pink.
