There's a catalog of Hokie merchandise we get a few times a year, I think from the bookstore that has pieces that can be used to decorate gardens, as door stops, and as desk items. But they're about $100+ depending on size and engraving.
Saltpeter is the common name used for several different chemical compounds, specifically for potassium nitrate and sodium nitrate. Potassium nitrate is commonly used in gunpowder, and sodium nitrate is found in fertilizers and explosives.
Sodium nitrate, also called salt peter, shares many applications with potassium nitrate. Both can be used to manufacture nitric acid, to propel model rockets, and to increase the shelf life of meats and other foods. Sodium nitrate is also used to manufacture glass and enamel.
