Sodium silicate sand, commonly known as water glass sand, is a mixture of silica sand and sodium silicate solution. One of its key advantages is its ability to create thin molds without the need for a binder with organic components. Sodium silicate sand is typically used in conjunction with carbon dioxide (CO2) to harden the mold, making it an efficient choice for intricate and delicate components. Its resistance to high temperatures makes it suitable for casting aluminum and other non-ferrous metals.

At its core, sand casting glass involves shaping a mold from sand, typically mixed with a bonding agent to help it hold its form. The process begins with the creation of a pattern, which is usually crafted from wood, metal, or other materials. This pattern is then pressed into a compacted sand mixture, forming a cavity in which the molten glass will be poured. Once the pattern is removed, the mold is ready for the pouring process.
