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.
Salt peter typically refers to the chemical compound potassium nitrate, though it may also refer to sodium nitrate. Salt peter was once collected from decomposing material, but today, it is generally manufactured by treating sodium nitrate, mostly mined in Chile, with potassium chloride and collecting the precipitate.
