WARNING

This product is made of GLASS. A glass product can break, and there is a fear that if impacted, breakage could occur, pieces could fly off or fall downwards, and injury could occur. If, in any case, breakage does occur, please be aware that broken edges are sharp, and could be a cause of cut injuries, and take appropriate care accordingly. If use of a handmade glass item is continued when a crack or other defect has occurred, and/or further attrition occurs, then there is a fear that the product's strength will be remarkably reduced, and that this will become a source of breakage, which may cause physical injury and/or damage. If you discover a crack or other defect during use, or when the glass item has been used to a degree where it has deteriorated or where attrition has occurred, then always discontinue use! Please take precautions when using glass items in rapid heating or rapid cooling situations. Glass expands and contracts as it is heated and cooled. In the event of an extreme change in temperature, a crack or cracking may occur. Additionally, glass item will retain heat and serious burns may occur.
