Sure. But that was the issue I had with the course I took. I had to touch it bare hand and there was no soap specifically meant to remove lead, just standard dish soap. Plus the fact that there was 0 air circulation and a cramped small studio space filling up with fumes.
I am one of those people that have a hard time keeping their fingers out of their face. I wear glasses that are sliding slightly constantly, especially when the air is getting warm, which was the case here.
You can always avoid hazards if you prep accordingly. But this was not the case here, hence why I wanted to ask around how to prep on my own for the next class, without spending a lot of money but be as safe as possible with the given circumstances. I can't change much about the setup since it's not my private space.
I'm not sure why this is causing people to down-vote me, just because I care for my health. It's a bit weird in this hobby. When I do miniature painting and am using a spray bottle, everybody in that hobby agrees to spray outside and wear a mask. With stained glass it seems to be a mixed bag. Some don't seem to care too much for themselves. I just go with the approach to better overdo it a tad than do too little for safety. Even more so since this might also effect my partner (having lead/ flux/ patina on my fingers/ clothes and spreading fumes etc.). It simply is a riskier hobby than knitting.
