Lee,
Thanks for this. I have been interested in many details covered in this. The naming of acetic and formic acids are particularly interesting as I was wondering if acetic was the organic acid formed as kilns with organic matter were heated. The destroy my kilns when I bisque stuff with corn in it. Knowing that it is acetic acid lets me know that it cannot condense on a surface above 118 C (formic acid 100 C) and that I probably can get it to condense as it leaves through a vent if I give it a suitably cool container. Other acids are mentioned later in the paper and I will need to be well awake and sharp to read that far in.
I believe aldehydes may be given off earlier than stated and my experience is that charring happens well above 200° C, but seeing this in print is great. I will use my aldehyde detector (big nose) to see if I can verify these.
This sentence:
But for charcoal spontaneous ignition is re-
ported at temperatures as low as 150° to 250° C
on Page 5 seems to contradict what Cardew says about soot.(Pioneer Pottery page 210) "The smoke can be burnt inside the kiln....ignition temperature of carbon (400-800 C , according to Bose)"
Although it could be residues in charcoal that allow its combustion.
Anyhow,
Thanks for posting
Louis
