Blue green flecks in ash

Copper staples from packaging or possibly softwood pellet?

Colored flecks in ash are usually an indication of metallic ion present. The blue or green suggest copper or possibly cobalt.

Speaking of Cobalt, I'm thinking of buying a set of Cobalt brand hole saws. Just thought I'd throw that in there !

I never would have thought of cobalt in wood pellets though. As to colors in the ash I might have thought that minerals in the wood might produce this but yes, certainly metal would.. Now as to whether it's metal in the pellets make up or in between the pellets in the bag becomes the concern. As someone mentioned staples, staples through the auger is not cool.

I know that because of laws some people can only cut dead trees on property that if spiked with copper the tree would die. Staples that I stated may have been some material recycling as some pellets are made from old pallets. Copper wire from who knows where. High copper sulphate can be in pine trees. Had rabbits chewing on our trees and peeing blue.

I fed them some copper coated lead too.

Was that high velocity lead?

I am currently burning Allegheny hardwood pellets and I see blue/green material in the ash also. There is occasionally red/orange as well. You can actually see it in some of the pre-burned pellets. I thought maybe it was some kind of dye in the wood that they used ?

Dyes are organic in nature and I would be surprised if they survived the fire. Pigments are often mineral based, but they wouldn't be absorbed into the wood.

Now I am going to speculate about your blue-green flecks. Could it be fragments of the metal belt lacing? For those that do not know lacing is what holds conveyor belts together.

I got the belt in my bag and you got the fragments of the lacing? Our bags are of the same date.

Just a thought.
