This item is constructed from high borosilicate glass, which can easily shatter if subjected to uneven heating, with a maximum safe temperature of 150 ﾡ￣C. The primary causes include quick temperature changes while in use that can lead to fractures. When heating, it is advisable to preheat gradually, starting on low heat for 5 minutes, then increasing the temperature to around 50 degrees Celsius before moving to medium-high heat.
