Search specific oxides or elements:
Choose a major element from the drop-down list and enter a minimum or maximum percentage for that element. Although you can set constraints for multiple major elements in this search, at this point it functions like other sub-category searches and will join multiple elements using "OR". A last caveat about chemistry searches: this search uses values as entered in the database, normalized or not normalized, although all search results are returned as normalized values. Some search results may include normalized values that were not in your search parameter because their non-normalized value is within search parameters.
