I saw a video once on line where a guy was lighting his  spice pipe with something very much like these flamless torches..and it vaped quickly!

I imagine there is a butane flame inside the heat tube? but the flame doesnt come out only heat!!

Says it will heat up to  650 c...   120 degrees.. F....to 650 degrees ..C...

But you dont need to hold it long and the spice should vaporize long before it reaches too high a temp..

I guess it would vape spice withoin 3 or 4 seconds!

I need to get one and give it a try!they are not that expensive maybe 30 bucks?
