Safety note: Exact mineral composition and bottle construction vary. If a manufacturer does not clearly identify materials that contact drinking water, choose another design.
Safer design principle
A sealed crystal chamber reduces direct mineral-water contact and simplifies the material-safety question. With direct-contact designs, you need reliable information about the specific stone and how it was processed.
Cleaning matters
Follow the maker’s instructions. Cracks, seals and decorative chambers can create places that are harder to clean than a plain bottle.
Retire damaged bottles
Do not keep using glassware with cracks or compromised seals.
