Pondering on it some more, I'm leaning towards: soak quartz in water and scrub sediments off, break quartz into smaller pieces, add quartz to muriatic acid from Wal Mart, soak for 3 days, rinse quartz in distilled water, then let soak in distilled water for a week changing water once or twice, transfer supernate to a beaker and boil off the acid into condensing line leaving me with iron oxide for rust effects, take the now hopefully free of solvent quartz pieces and crush them into white silca sand for basing minis.
