It is true that most sand is made of quartz, and that most of this quartz arises from weathered granitic rocks, of which the main minerals are quartz, orthoclase and plagioclase, usually with some mica, quite rarely some amphibole and almost never olivine. In the magma olivine and quartz react to make either amphiboles (if it is a very hydrous ...

Step 1 – Prepare the Edges. First, thoroughly clean the countertop edges you wish to sand using isopropyl alcohol. Allow the surface to fully dry. Then, tape off the top surface of the countertop several inches back from the edges. This protects the surface from accidental sanding and keeps dust away.

I too have been wanting some decent quality quartz sand for a while, and the other day I found the perfect stuff in an aquarium shop being sold as a substrate. Mined in the Philippines, this sand is pure white and quite coarse (2mm grain size) with a very small quantity of shiny mica added to give it a sparkle.
