After sanding and cleaning, you would heat the panel with a torch, then rub a block of Sal Ammoniac over the area to be leaded, the Sal Ammoniac would coat the steel, then as you heated it to lead melting temperatures the Sal Ammoniac would break down to acid and chemically clean and etch the steel so the lead would stick. Then the lead was filed and sanded smooth and painted.</div><div><br></div><div>Stuart</div><div><br></div><div><br></div><div><br></div><div id="composer_signature"><div style="font-size:85%;color:#575757" dir="auto">Sent from my T-Mobile 4G LTE Device</div></div><div style="font-size:100%;color:#000000"></div><div style="font-size:100%;color:#000000"><!-- originalMessage --><div>-------- Original message --------</div><div>From: Stephen Rees via Stagecraft <stagecraft@theatrical.net> </div><div>Date: 5/4/2018 12:54 PM (GMT+01:00) </div><div>To: jdunfee12@yahoo.com, Stagecraft Mailing List <stagecraft@theatrical.net> </div><div>Cc: Stephen Rees <Stephen.Rees@fredonia.edu> </div><div>Subject: Re: [SML] Sal Ammoniac smoke </div><div><br></div></div><div dir="ltr">The heater cones were (are?) a ceramic cone with a medium-screw base wound with nichrome heater wire that was screwed into a base within a metal reflector and used as a very early space heater. Usually had a medium-gauge welded decorative wire cage over the face of them. Scary from an operational standpoint let alone the fumes given off by the sal ammoniac. Another example of a device used for something other than its original purpose. <div>Steve</div></div><div class="gmail_extra"><br clear="all"><div><div class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><div><div dir="ltr"><div dir="ltr"><div dir="ltr"><div>Stephen E.

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.
