[Stoves] Experiment anyone?

[frank]

Dear Crispin,

This could be the answer. I just tested some bamboo that I ground up to 
experiment with and there is a lot of salts. I am experimenting to 
determine what type of salts they are. Also the coco hulls can have a 
lot of salts. I don't think redwood bark does but I have not tested and 
I don't think cork does but still I have not tested. I got some email 
from Kevin and he talks about fire retardant. I wondered how they work. 
Perhaps taking in some of the heat via chemical reaction before it meets 
the carbon?
