Common Questions
How does the NAISU N1 create clear ice diamonds?
NAISU N1 leverages directional freezing and crystal seeding technology to craft crystal-clear ice diamonds. This innovative process eliminates dissolved gases and impurities, resulting in visually stunning ice spheres.
How can I make the clearest ice possible?
We've achieved perfectly clear ice with tap water, and you can too! However, if you live in an area with hard water, we recommend using distilled water or water that passed through filters equipped with reverse osmosis technology. These filters effectively remove impurities, resulting in clearer ice. Alternatively, boiling water before freezing can also help reduce dissolved gases, further improving ice clarity.
How long does it take to make an ice diamond with NAISU N1?
The freezing process may take between 14-18 hours, depending on your freezer's temperature.
How do I clean my NAISU N1?
The food-grade silicone mold and stainless-steel cup are a breeze to clean! Just wash them with warm water and mild dish soap, then let them air dry. Plus, they're fully dishwasher safe, ensuring thorough disinfection and keeping them free from mold.
