Baking Soda! great one! i never thoght about that one! that would work better because you can extinguish small fires with it, because it produces carbon dioxide when heated. i heard this somewhere.
Hmmph. One learns things in the most unexpected places. I always thought it just smothered the fire, and assumed any other non-flammable solid would work as well, such as salt (but NOT flour!). Now I know Baking Soda has a specific advantage. (I did confirm that it breaks down and releases CO2 when heated.)
