Knowledge Dust is a mixture of silt, sands, and some granules or pebbles from thousands of locations, but found together in the geologists lab.  

 

Earth-life

​

Quite possibly one of the most potent dusts for working with people in any way. During my time as a geoscience lab teacher (Lane Community College, University of Oregon, University of Wisconsin-Eau Claire, and Treasure Valley Community College) I ritualistically collected the rock remains from the lab tables after each mineral or rock identification lab. From minerals like galena or halite to rare rocks like blueschist or mylonite, this exotic dust represents all of earth materials in one sample and we collected while transmitting this knowledge from geology teacher to student.
