Yes use the sandwich method broheim better than snow cone!
What you can do is if you have someone handy - in case.
Get one or two knives on the stove top, HoT Knives, and when red use that by placing on top of cone, so it looks flat on top sideways blocking top of cone, and lift edge of knife to fan etc.
perfect smoke, no flame, BUT try and have a sitter; or just be quick, a HOT knife will smoke that up pretty quick. But will always be below flame heat and will burn evenly.
TRY PUTTING THE DMT MORE NEAR THE TOP OF SANDWICH, SAY THREE QUARTERS TO THE TOP, THAT WAY IT DOESNT MELT THROUGH IF YOU ARE SCARED OF THAT,
AND SMOKE SLOW,
IF YOU ARE GOOD AT HOLDING IN SMOKE AND
'PLAYING THE BONG' THEN SIMPLY GET JUST A GLOW HAPPENING AND THEN USE YOUR
NIGGA LUNGS TO CHERRY IT UP.

plrRRRRRRRRR
*** edit
Sorry buds but that pipe/bong looks mighty small is it?
and with no rush hole it does not look like you will have the most control with that apparatus, but it would be fun to puff it on, like a "Jeffrey" pipe.
I always use a water bong with air shotty, want to try a V. Genie soon.
