Obtain silica sand. Also called quartz sand, silica sand is the primary ingredient in making glass. Glass without iron impurities is sought for clear glass pieces, as the iron will cause the glass to appear greenish when present. Wear a face mask if handling extremely fine-grain silica sand. If inhaled, it can irritate the throat and lungs.
