Well, after talking to
@mvapes I decided that even 700°F was too hot for manually heated quartz. It can still burn your oil and foul the nail. I also discovered how critical a PROPER carb-cap is.
Ill write things up in more detail when I'm not so pilted, but here is a video highlighting both of these "advances" in my personal technique.
The dab hits the nail at ~575°F if you're keeping score... and check out what a huge difference that carb cap makes!
Also IDK if you can tell, but Im pulling like a mofo after a while in order to further distribute the oil across the nail's surface. You can probably hear the whistle from the carb hole in the cap, lol. In retrospect I think i pulled a bit too hard. There should be a balance between oil distribution and premature cooling of the nail.
Also special thanks to
@masaki for hooking it up with that sweet Ti dabber and cap.
I should also note that this temp works with my CLEAN (read, it was new when i started) nail. Ive never dabbed over 600°F on this, and Ive hit it at least 2 dozen times... and look how clean it is still! My last nail was completely opaque by this point in its life.
Also, that yellow residue you see burns off completely, so its back to brand new looking every time. In any case, I found you need to increase the temp by 50-100° if you have that black insulating residue already built up on your nail.
