THE RISK OF CRYSTALLINE SILICA EXPOSURE: THE FRAC SAND

Oct 05, 2014Photo above shows a recent train derailment where frac sand (the toxic crystalline silica) was spilled. In 2012, the National Institute for Occupational Safety and Health (NIOSH) released field study findings concerning worker overexposure to airborne silica during hydraulic fracturing operations.

How to Grow Your Own Quartz Crystals

Jun 24, 2019If you are truly determined to grow quartz crystals at home, you can grow small crystals by heating silicic acid in a pressure cooker. Silicic acid can be made by reacting quartz with water or by acidification of sodium silicate in aqueous solution. The main problem with either technique is that silicic acid has a tendency to turn into silica gel.
