HOTTO-G MUG CUP / PURPLE

This heat-resistant glass combines the functionality of heat-resistant glass with the texture of colored glass, which develops during the manufacturing process. It can be poured with boiling water and microwaved. Note: As this is a handmade product, the color, appearance, size, volume, and weight may vary slightly. Air bubbles may form when the glass is rolled up. In addition, patterns may appear in the base color, which occurs when the color develops through tarnish. Please understand that this is a characteristic of handmade products. *Actual colors may differ depending on your monitor settings. 1) "Heat-resistant glassware" is defined as a product with a heat-resistant temperature difference of 120°C or more but less than 400°C. 2) "Heat-resistant temperature difference" refers to the temperature difference at which a sample of glass remains intact when kept in an incubator at a constant temperature for 30 minutes, then immediately immersed in cold water for 1 minute. 3) Usage Classification [For boiling water] Can be used with boiling water. Usage Classification: This product is intended for use with boiling water, but is not intended for use as a heating device. Heat-resistant temperature difference: 120°C [For microwave use] Can be used in a microwave. Usage classification: For use in cooking, etc., using electromagnetic waves for heating. Heat resistance temperature difference: 120°C (320°F). Handling Precautions ●Do not use over an open flame. ●Do not heat empty. ●When pouring boiling water into the container or after heating, the container will be hot, so be careful when handling it. ●Do not drop from a high place or subject it to sudden impacts. ●Sudden temperature changes may cause it to break. (When cooking, wipe off any moisture from the outside before use. Avoid pouring cold water over it. Do not touch the hot glass with a wet cloth or place it in a wet place.) ●When cleaning, do not use abrasive brushes, metal scrubbers, or cleansers as they will scratch the glass and cause breakage. ●Avoid using it outside of the intended use. About NOTOJIMA GLASS FACTORY The history of Notojima Glass dates back to 1984, when Ishikawa Prefecture invited the Tokyo Glass Research Institute to establish the Notojima Glass Workshop in a repurposed, decommissioned school building. The initiative aimed to develop innovative glass techniques, attract tourists, and stimulate regional growth. In 1991, the Notojima Glass Art Museum was inaugurated, showcasing diverse contemporary glass artworks. The workshop's establishment coincided with the opening of the Notojima Bridge, which facilitated the island's development. The project creatively repurposed the idle school facility and drew inspiration from ceramic artists in Tsubata Town and Venetian glass production on Murano Island. Heat-resistant rainbow glass is a remarkable innovation that combines aesthetic appeal with practical utility. Engineered with specialized components that create a dynamic color-changing effect during rapid heating and cooling, this glass offers a unique visual experience while being safe for microwave use. Maintaining the transparency of conventional glass, it incorporates ceramic-like textures and vibrant hues, resulting in a sophisticated and elegant design. Each piece is meticulously handcrafted by skilled artisans, showcasing the intricate craftsmanship and artistry of handmade creations. The Hotto-G series presents a diverse range of options to suit various preferences. The "Standard Series" emphasizes minimalist elegance, the "Melody Series" highlights refined details, and the playful "Dotto Series" adds a touch of whimsy. These collections reflect distinct styles while maintaining the high-quality standards synonymous with this innovative glassware. Originating from Noto Island in Ishikawa Prefecture, these heat-resistant glasses seamlessly merge regional charm with superior design. Perfect for enhancing everyday living, they bring both functionality and an artistic touch to modern households.
