We got the biodegradable polymer from Coim Inc.  and have begun to test various ratios of sand aggregate to polymer.   Our early hypothesis that a 60:40  sand to polymer ratio would be the most effective seems to be in error.  We have begun testing ratios between 80:20 , 85:15, and 90:10 .    Having made a couple TEST MUFFINS, we are letting them completely set.  A piece was placed in water to begin to observe the degradation time.  3 mixes and 25 pairs of vinyl gloves gone.
