The selective diffusion of helium through fused quartz is the basis for a method of purifying helium by essentially "screening out" contaminants by passing the gas through thin-walled quartz tubes. The diffusion of helium, hydrogen, deuterium and neon through fused quartz is accelerated with increasing .

But on some beaches, the sand grains are iron-stained (oxidized like rust), departing a light yellow to yellow-brown color to the beach. A large part of the brown coloration of our beaches also comes from brown-stained shells that have broken down into small sand-sized fragments in the surf zone and have become mixed with the quartz sand grains.
