I would be surprised if the people at my LWS would know the difference. I always called it brass because I didn't know any better. Now I'm more careful because there might be pedants around.

I asked the LWS person if they sold brass flux and they pointed at the stay-silv. Wonder how many people they have screwed over with that bad information. I understand it almost works

I'm curious how much penetration you can get with the stack of dimes fillet style of brazing.
