One thing to consider is that you can actually apply too much heat with a ceramic disc.

I have a friend with an identical setup as me (GVG+VG disc) and he has been complaining that he isn't feeling anything lately.

When I came over I decided to clean his instruments: Rinsed the GVG with Acetone and burned the VG disc with his Arc.

After 2-3 seconds of applying direct flame to the VG disc it started smoking as well as smelling very intensly of DMT and literally caught fire for 10 seconds.

The only explanation I have for this phenomenon is that he applied too much heat in the vaping process so the spice melted down into the disc without vaporating.

I think that this can be very dangerous as more and more DMT collects inside the disc until it's saturated and at some point when you'll vape correctly you'll end up with taking a very strong hit (>50mg), at least that's what I think will happen.

Any opinions?
