Please see below a small offlist discussion which I think was aimed at<br>
[stoves]<br>
. I found it interesting that kaolin (same as fullers earth or bentonate<br>
clay I suspect) modiies the combustion in this way.<br>
<br>
Now to find a Vietnamese shipping company that can handle all the duies and<br>
transport for dhipping Delivered Duty Paid.<br>
