Quartz sand, ground glass of any color, or quartz rock will do just fine for that kind of work. FYI -- For a few bucks. You can also go over to your local big box hardware store and purchase a 100 pound bag of 30 or 100 mesh sand from the cement and brick aisle. The active ingredient is the silicon dioxide, or SiO2.

The solubility of oxygen in solid and liquid silicon has been studied extensively as it is important for high-quality silicon production. Data analyzed (Schnurre et al., 2004, Tang et al., 2010) show that the three-phase equilibrium L = (Si) + cristobalite is a eutectic reaction, where the eutectic composition was calculated as 47.3 ppm O (at.) in solid …
