Although lead-free crystal contains the word "crystal" in its name, it is not actually true natural crystal. Lead-free crystal is a man-made glass produced using modern techniques, typically made from high-quality glass materials like borosilicate and does not contain the traditional lead component. The advantages of lead-free crystal include being environmentally friendly, safe, and easy to work with, making it widely used in high-end glassware such as drinkware and decorative items.
