Annealing marks

[Lucreau]

Have an ugly annealer and did about 50pcs today. Annealing until it just flashes orange while in a dark room and I’m getting these dark spots on about 2/3 of the case neck. I’m assuming it’s the last spot that the flame hits?
In the pics I’m rotating the brass

To me, it looks like left over residue from cleaning being burnt.

Well it’s in the name. Ugly annealer, ugly necks. Lol

Amp annealed .223

Perhaps the brass stops spinning just before it drops, or sometime during the process ?

Looks like left over residue as noted above. Maybe sizing wax?

I anneal as my first step in reloading so only have powder residue which doesn’t do that on mine at least

To me ... it looks like ... um ... you should buy an AMP.

Are you doing stainless tumbling? I have seen kinda similar marks when annealing if I didn’t wash the brass really well and still could had a thing layer of soap or cleaning agent on it.

I get very small blue marks sometimes that I think are that.

Yeah I’m using steel chips. That was my thought as well was there might be some soap residue left ovsr

Thanks for those that had actual advice. It was definitely just left over residue from cleaning. Cleaned this piece more and it’s perfect
