This makes the flame go out..

Water puts out fire by creating a barrier between the fuel source and the oxygen source (it also has a cooling effect which has to do with the energy required to convert liquid water into water vapor). It does this because it is a completely, 100% oxidized material.

Which is lower than the recommended 20% of kiln dried logs. So again with this type of product, the smoke output will be less, and they will burn with a good heat.
