This is the first time I have actually ever seen ceramic proppants.
When we got out of the car to look at the sacks close up, I almost slipped and fell. The proppants are extremely slippery. In my hand, my first thought was this is just like graphite lubricant. Perfectly spherical, almost too small to see individual spheres, they are that small. They leave no ash, dust, or discoloration on the hand with casual inspection. Something tells me with heavy handling, the hands become very gray.
Below: This was the only sign of security in the area. Had this sign not been there, I would have picked up one of the sacks and put it in the trunk of our sedan. I walked into the area around the sign: I saw no "watchman on duty." I saw no video camera. I neither saw nor heard any dog. Something tells me that even if you walked off with a bag of Chinese ceramic proppant, you would a) have no use for it; and, b) have no one to sell it to.
