However, I have never seen this done, nor even seen what such a heating cone looks like. A search for a "heating cone" shows up some cone-shaped systems which you use to heat a bearing (I am guessing to expand it a bit, to put onto a shaft). Is that the sort of "heating cone" used for smoke?</div><div><br></div><div>A search on Youtube also turned up nothing except how to clean your soldering iron. I also searched "<span>ammonium chloride", since that seems to be the same stuff. But, again without success.</span></div><div><br></div><div>Anyone know of a site that shows a picture, or ideally a video of such a contraption in operation?</div><div><br></div><div>-Joe</div></div></body></html>
