All I know is the actual PID temp, not the actually quartz, but I imagine if the coil temp is 525, the bowl will be in the 400's? Either way, WAY too much pooling/waste! And then gross fuming that makes me sick. Can't stand the smell of dabbing, and the bowl smells worse than combustion after even though it's just condensed concentrate. Nasty! And too wasteful IMO.
I don't know man, I don't take big enough dabs to get pooling, I can easily say I've never had a dab pool in my life.
It's weird because your comment about pooling makes the temp sound super low, but your comment about the fumes makes it sound super hot, so I have no idea what's going on there. Bunko Chinese enail perhaps? I can't stand the combustion smell either, if I was getting that toxic smell you describe when I dabbed I definitely wouldn't be doing it! I just hit some of this Fire OG, it's pretty tasty. I wish I could help diagnose that fuming cause that's certainly unfortunate brother!
