I fixed my friends bowl using 2 ton epoxy. It's a ceramic piece and looks perfectly fine now. I was wondering if flame can melt this glue. I can't find it anywhere online so I figured I'd try here.
for real? Only a little leaked through to the inside and I whipped it with a Q-tip several times til nothing else came out.
I wouldn't risk it. I don't know how your piece heats up, but that's a bit too close to the heat source for comfort, imo. If you managed to heat it up enough to combust or give off fumes, it would be very unhealthy and probably dangerous. Not worth it.
