〇: Essentially safe.
When the above factors are present, or there is some doubt, use a metal bowl for safety.
3) Avoid the application where charge and discharge of pressure to/from a standard bowl is switched
frequently. This may damage the bowl. A metal bowl is recommended in these cases.
4) Protect from ultra violet ray and radiation heat by shield.
