I've charred the ends of my golf tees, but never ignited one. It is possible, but... much more likely to char one... and, I suppose it would be more likely to just warp or misshape a pewter one. But, then you are also taking a chance of getting tin fumes mixed in with your smoke. But, whatever... I just state this as a precaution... something to be aware of.Sure. And wood tampers will also ignite if left pressed to an ember for long enough.
