If the G3 is all glass, how is it compatible (but not recommended) with induction heaters as the web page states?
My guess is that a slow flame allows the glass to absorb more energy than the quick heater does heating just the cap? "Compatible but not recommended" might mean, "it'll heat the cap, but the glass won't absorb enough radiant heat to make vapor at the clicks."

Actually i just tried it and this is exactly how it seems: the cap clicks at a normal time but there's not enough heat in the tip to roast. Two b2b heatings yielded almost no flavor even.

Interesting. I always thought that during heating (induction or flame), it was the chamber that heated up, which, via conduction and radiation heated the cap, which clicked when the duo reached the right temp.

Based on your observation, the cap seems to be ferrous as well, and independently heats (and clicks) when exposed to energy via either source. Given how little thermal mass the cap itself has, and, therefore, its near-inability to transfer any meaningful heat to the glass chamber (does it even raise it above room temperature?), calling induction heaters as “compatible” seems to be incorrect, won’t you agree?

My understanding is that the cap radiates/conducts heat to the bowl quickly enough to begin to roast the herbs by the time the cap clicks. I think the bowl even slows the heating of the cap until it's caught up. It's possible I guess that some induction heating of the bowl would accelerate the process, but given how it works with a flame, it's plain that the bowl gets heat from the cap--the cap is right in the flame, the bowl is 'protected' from the flame by the cap, etc. The cap must transfer heat to the bowl.

I know the cap is ferrous, and it does react to either source. An IH will heat the cap to click temp on the glass bowl.

It does indeed seem a stretch. My first test above was with with the Wand/SK insert and after two rounds it just wasn't very hot. I just tried it again with the Camouflet Inductor and turning it down and using it back-to-back you can actually get it going. But it never really got as productive as you would expect with the cumulative heat. Hits were weak to almost normal. I hope others will chime in but so far I'm not getting a lot of satisfaction with an IH. Otoh, it's really good with a torch.
