Using the stone is straightforward. First, thoroughly rinse the flint with clean, cool water to remove any dust from packaging or transport. Place the rinsed stone into a clean container (like a glass jug, pitcher, or carafe) and fill it with your preferred water, such as filtered or boiled-and-cooled tap water. There is no specific ratio, but using the entire 250g package in 2-4 liters is a common starting point. Let the water stand at room temperature, ideally for 6-12 hours or overnight. Many users then remove the stone and store the infused water in the refrigerator, using it over the next 1-2 days for drinking, cooking, or brewing tea. The stone itself can be reused immediately in a fresh batch.
Key details to keep in mind:
- Cleanliness is important. Rinse the stone every time before use and inspect it for any visible buildup. If deposits form, a soft brush under running water usually removes them.
- The effect is subtle and builds over the standing period—it’s about infusion, not instant transformation.
- Use a container that’s easy to clean and doesn’t retain strong odors (glass or ceramic is ideal).
This product is not a substitute for proper filtration if your water source has quality concerns, unusual odors, or may be microbiologically unsafe. In those cases, use appropriately treated water as your starting point.
