Actually, contrary to the beliefs of many, the hot dip process of galvanized coating (ASTM A123) doesn't outgas under a cooking temperature. A much higher temp., above 700*F is required. Though this coating is physically stable at safe temeratures I'd still strongly suggest curing the can with and extended heat prior to use.
Abstract A common phenomenon in the process industries is the oxidation of the exterior surface of steel pipes used in superheated steam or hot oils networks. For their protection different coatings could be used. In the present work the performance of zinc coatings deposited with hot-dip galvanizing, pack cementation and thermal spraying was considered, in order to protect industrial equipment up to 400°C. For that purpose coated carbon steel coupons were exposed at 400°C and their behavior was examined with light microscopy, scanning electron microscopy and X-ray diffraction.
Thermogravimetric analysis was also used in order to observe in situ the oxidation phenomena. From this investigation it was deduced that in every coating a scale is formed that is mainly composed of ZnO, while Fe oxides were also detected in galvanized and pack coatings. The growth of this scale took place at the metal/scale interface. Moreover, as far as it regards the kinetics of the oxidation, it was concluded that the increase of the mass of the specimens is a function of the square root of the exposure time, which means that the scale formed is rather protective for the underlying zinc. From the above observation it seems that the behavior of zinc coatings would be excellent at 400°C. However, the presence of the Fe/Zn phases inside the galvanized and pack coatings led to the formation of cracks, which could expose the substrate and thus destabilize the coating. This phenomenon does not take place in the thermal sprayed coatings, where the Fe/Zn phases are absent.

neat idea, but I still would not use a galvinized can are zinc any plated can for that matter. not even an aluminum vessel.
heck i reckon the ole uds could come in handy turn her upside down and have at it.sigpicWal-Mart shopping cart undergoing heavy mods.

I will still err on the side of caution... Putting that many briquettes on and around the can, I think not. To close for comfort for me..
I'm not saying you cant use it.. I just dont trust direct contact with the heat source...Ken

I think I'll stick with the UDS.
And avoid galvanized stuff. Not that I disagree with the quoted article. You just can't be sure if all things are manufactured properly or where they come from these days.
I did like the word "Thermogravimetric" though. I'll have to try and weave that into a conversation this week.

Galvie aside (which I will pass as well) - any welder worth his salt will tell you that.
Galvie aside - what is this thing gonna taste like? I mean, yes, I do cook some of mine in a oven, and that ain't much difference, but...
I LOVE the idea, but I think a smoker is more in order - just sayin'.

Saw a Paula Dean episode where she made cornbread on a shovel over an open fire. She said this is how they "might" have done it in the old days. Now, in the old days if they could have a production assistant bring them a brand new, shiny clean shovel maybe. But I doubt too many people would want to be eating food cooked off a shovel considering what the shovel was probably used for in the old days.
