MEDIUM GRADE<br>This sand is a medium grade appropriate for casting medium size to<br>larger sized parts with safety and a level of precision needed for such parts. A slightly larger average sized (in terms of casting sand) grain of sand allows for the faster and safer release of hot gasses when casting medium and larger parts or parts made with higher temperature melting metals such as steel. A slightly larger average grain of sand creates slightly less detail such as may be required for jewelry or other finely detailed pieces of art or craft-work.<br>This green sand is formulated for the small foundry from products supplied to professional foundries. The medium grade sand used in this product is appropriate for casting parts with a level of precision not possible using inexpensive and coarse sand readily available at commercial retailers for construction and landscaping purposes. This sand, manufactured by U.S. Silica Co., consists of 98.7 to 99.9 Crystaline Silica, less than 1.1% Aluminum Oxide, less than .1%  Iron Oxide and less than .1 % Titanium oxide. It will withstand furnace temperatures in excess of 3100 degrees fahrenheit before melting. The professional industrial quality binder used in this product is a specific grade of Volclay, a uniquely formulated smectite clay engineered for metalcasting by the American Colloid Company (ACC).<br>This product is engineered specifically to cast metals including aluminum,<br>copper, bronze and brass in a small foundry with safety and precision. This product is sold dry and 15 to 20 fluid oz. of water per 12 lb. quantity must be added. Additional 8 oz of ACC Volclay binder also included per 12 Lb. quantity of green sand purchased.
