Smile Desert Sand

Below is an excerpt from a website that discusses the insulation property of sand:
"Temperatures in Namib can reach as high as 150 degrees on the surface of the sand. A fraction of an inch could mean a 30 degree temperature difference. The sand , as well as shade, act as insulators to the intense sunlight found in Namib Desert. "
Assuming that the above is correct , can sand be used as an insulator below the hearth floor and on top of the dome (possibly in place of vermiculite)?

No. Deep sand in the desert stays cool because it conducts the cold from below. Caves are always 50 degrees. It's not remotely an insulator.

The problem with sand as an insulation on top is if you get cracking, sand will get onto your meal you are cooking. V'lite is much coarser.
