What is lead-free crystal glass?

To understand what is lead-free crystal glass, we need to first understand what is crystal glass. According to EU guidance, when a glass contains at least 24% of lead, it then can be called crystal glass. Therefore, lead-free crystal glass should actually be called fine glass.
