The item for sale is 1.1 Lb (18 Ounces) of Silica Gel (SiO2). You get 3 bottles each containing 6 ounces of product. Silica Gel is an effective desiccant that absorbs moisture from the air around it due to its nano-porous silica micro-structure, Silica Gel. This Silica Gel is non-indicating, meaning the beads are colorless and clear. The beads are 2-4 mm in diameter (roughly 6 mesh) and have the following range of absorption capacity: 11.2% at 20% Relative Humidity, 23% at 50% Relative Humidity, and 32% at 90% Relative Humidity. To reuse these beads, simply heat them at 120 °C (250 °F) for 1–2 hours. For Sodium Silicate (Waterglass), check out our other listings. Our bottles are made of durable Polypropylene Plastic, which is a natural, translucent, lightweight, durable, and chemically resistant copolymer. The screw-top is completely leakproof. The bottles’ round shape makes them a perfect addition to any shelf or travel kit. Every bottle we ship is sealed in plastic with the screw-top shrink-wrapped.
