Method validation was carried out using 55 real-world bulk samples, containing between 1 and 75% (w/w) α-quartz. The method is capable of quantifying α-quartz down to 1% (w/w) in routine analysis. However, the method is unlikely to allow routine quantification at 0.1% (w/w) as currently mandated by regulations.

Grind away the roughest edges with a small rotary tool after the stone is clean. If your quartz has large pieces you want to remove, cut off them off by sawing through them with a cutting wheel. Place the edge of the wheel against the part you want to cut away, then apply gentle pressure to grind through it.

grinding in liquid nitrogen were both investigated, but powders produced from each of these methods were too coarse for XRD analysis. While the Microjet 5 grinder can produce a fine- grained powder in a short time, the agate grinding set may con- taminate the perlite with quartz, so the Microjet 5 was not used.

Step 1. Sand the quartz surface with a hand-held sander, using the 200-grit sandpaper pad. Use smooth, even strokes and make sure to sand the entire surface. As you work, you may need to wipe away dust with rags. Repeat this process using increasingly finer grit sandpaper pads, ending with the 800-grit paper.
