An air-droppable wildfire retardant composition including Lassenite N
pozzolan is a natural siliceous (amorphous) mineral, consisting of the
layers of diatoms and volcanic tuffs of Northern California's Cascade
Range. The Lassenite pozzolan is mixed with a thickener such as Bentonite
clay, a measured volume of water forming a slurr-type mixture capable of
suspending the particles of pozzolan in a mixture having a viscosity
sufficient to avoid solids separation. The inventive fire retardant
contains substantially three innocuous ingredients which have no harmful
effects to the atmosphere, plant, or animal life.
