Started these two last night... Brass GP Paps 18650, sanded,
salt and saturated ammonia, Copper Mutant 26650, sanded,
salt and saturated ammonia
A shot just before bed last night (approx 8-10 hours ago)
And now, here I am at work, still watching over my patina-ing babies, giving them the nutrients they need to grow that gorgeous patina

this is at about the 14 hour mark
These will probably go another 8-10 hours, probably won't wash them off until I get home from work tonight, want to really bring out the blues on the Copper and see what happens in 24 hours on Brass as I've only ever done fast patinas on brass and it usually turns out mostly brown which I'd like to avoid this time
Also I don't know if anyone is on Instagram but I post photos there too, Nik_Zak
