Brand: OJIKA Industry Material: Ceramic Bottle Type: Reduced Hydrogen Bottle Features: Static Electricity Protection Size: 230mm x 80mm x 80mm Weight: Approximately 540g Capacity: 850ml Material: Ceramic This bottle is different from reduced water or hydrogen water made using the electrolytic water method. It faithfully adheres to the laws of nature and creates tea with a low oxidation-reduction potential by utilizing ions and static electricity generated from the combination of small vibrations of matter. When you put tea in this bottle, negative ions, which are present in the air, gradually overflow, and the tea becomes low-potential while the amount of hydrogen also increases. With frequent use, the container "remembers" and the tea's potential becomes lower, making it easier to create tea with a high hydrogen content. This bottle is not a machine, so please enjoy using it while feeling the seasons. In addition to tea, you can also use it for fruits and dashi (broth). ☆What is Oxidation-Reduction Potential (ORP)? Oxidation-reduction potential is an indicator that shows whether a substance is likely to oxidize or reduce other substances. If this value is positive and large, the oxidizing power is strong, and if it is negative and large, the reducing power is strong. Simply put, it is an indicator of the ability to reduce (restore) something that has been oxidized (meaning rust, decay, or aging).
