How do you know if glass bowls are food safe?

To determine if glass bowls are food safe, look for labels or markings indicating they are made of tempered or borosilicate glass, which are more resistant to thermal shock and less likely to leach chemicals into food. Additionally, check for certifications such as FDA approval or compliance with food safety standards. Avoid using glass bowls with visible cracks, chips, or scratches, as these can harbor bacteria and compromise food safety.
