Topic: Pottery Drum Roaster, aka +My Lapse in Netiquette (5 msgs / 122 lines)
1) From: jim gundlach
I use a BBQ rotisserie drum roaster every now and then.  The unit I 
have is made of brass and steel.  I see a couple of problems with a 
pottery version.  The major one would be at the end of the roast.  It 
is quite difficult to get the beans out and starting to cool quickly.  
I can imagine so many way that a pottery drum would be broken and the 
beans are lost that I could not recommend even trying.

Yep...pottery would break quite a bit more easily than stainless steel, for
sure.  Using a tapered end on the pottery drum, and no door that has to be
manipulated to release the beans would help.  Just take the spit/drum from
the grill and dump.  It would be significantly heavier too.  I think the
'wow' factor for a potter to make his own drum might be a plus, merging two
passions.
There may be no roasting advantage at all, but I think it would be
interesting to try.

I cannot speak for the drum, but certain kinds of ceramic material 
are excellent for coffee-bean roasters.
My preferred mode of roasting is in a small hand-held ceramic pot. 
The body of the pot is curved in such a way that it is mostly 
covered, with only a small side-hole for air intake and dumping the 
beans post-roast post-haste, and a second small hole at the top for 
exhaust and visual monitoring purposes. The material of the pot is 
grey-black (looks like some kind of stone-ware) and it feels heavy 
and dense for its size. It is also stronger than most other ceramic 
ware - I have dropped it onto a wooden floor a number of times 
without any noticeable damage.
In practice, the ceramic pot is tricky to use and requires lots and 
lots of trial-and-error practice. It has a tendency for producing 
uneven roasts unless you know what you are doing (and are also 
awake!), and is at the opposite spectrum from push-button roasting.
But once you have the technique(s) down, the results are well worth 
the trouble. Recommended for people who like roasts that are complex, 
but don't mind a slight tendency toward deep-bodied heaviness.

I was wondering if anyone has considered a ferro-cement drum. It could be 
made very thin, any shape and size, and is basically indestructible. I have 
no idea of the heat handling capabilities of it....One good thing is that 
you would not need a kiln to create this - just the mesh and the cement....
Just a thought...
Ciao,
Angelo

Life cycle would be way short IMHO-heating and cooling would pull it apart.
Cast iron -al la Hothow"s- would be ideal.
