Hey folks, as you can tell from the handle I'm just now getting into casting my own silver using .999FS shot, bars, and rounds. I've got everything I should need, aside from the big question. I'm planning on working outside and from what I've been told I don't need a respirator since I'm using .999 fine silver. Obviously with Covid getting a respirator in my small town is impossible, everyone is out and won't be getting more till this situation is over. Thoughts, opinions, and experiences are greatly appreciated!
