I've been using quartz sand from Lochaline Quartz Sand Limited for some time now, and I must say, it's the best I've found. The sand is finely graded and consistent, allowing me to create intricate designs in my glasswork. The customer service is excellent, always providing prompt assistance. I highly recommend Lochaline Quartz Sand Limited to all glass artists.
