Pepita glass engraving

Pepita glass engraving (Spanish: grabado de pepita en vidrio) is a technique of engraving on glass used by artisans of Mexico, in which an aluminum oxide grinding stone or wheel is used in a grinding machine to manually carve out patterns of small, decorative pepita-like shapes in glass objects. Machine-made, molded glass products are also manufactured in a style that mimics the artisanal technique.
