I'd be real careful diddling with silica. Amorphous glass is taffy if you scale it right. Crystalline silica properties are sensitive to water content - and alpha-quartz is a sponge parallel to its crystallographic c-axis. Internally wet quartz is geologically ductile. Quartz as resonant frequency stabilizer is negatively impacted (screwed) by ppm water. The industry jumps through hoops for sufficiently dry quartz (e.g., EIA Standard 477-1, JIS C 6704, IEC 60758; swept quartz for aerospace).
