■Glass is fragile
In extremely rare cases, glass can suddenly break without any impact or temperature change. This occurs when an internal force slowly acts on an invisible scratch on the surface, causing the glass to suddenly break after a period of time. When handling any glass product, please handle it gently to avoid scratches.
■ Be careful of fires
A convergent fire is a fire that occurs when sunlight is concentrated at a single point by a transparent object like a convex lens or a reflective object like a concave mirror, igniting combustible material.
Since there are several to a dozen cases per year, the fire department is calling for attention to this as a cause of fire. <Preventing Convergence Fires> Effective measures include placing lenses and concave mirrors that may cause fires in places that are not exposed to direct sunlight, and closing curtains when going out to prevent direct sunlight from entering the room.
The glass used in Henry Dean vases can also be a source of fire, as mentioned above, depending on the placement and shape. Please handle with care.
