The terminology used by al-Rammah indicated a Chinese origin for the gunpowder weapons about which he wrote.[21]. By the 15th century, Europeans referred to it as saltpeter[9] and later as nitrate of potash, as the chemistry of the compound was more fully understood. It's important to note, however, that potassium is very reactive with air and water. Since rust is an oxidation product, this statement requires justification", "The Scientist, the Patent and the Mangoes – Tripling the Mango Yield in the Philippines", "Filipino scientist garners 2011 Dioscoro L.
