Halacha – Non-kosher microwave oven
Submitted by Eli Answered by Rav Peretz Moncharsh
Question: There is a non-kosher microwave at my place of work. Sometimes there is even residue of non-kosher food in it. Is there a way for me to heat-up food in it? I heard something about double-wrapping but I am unclear on the issue.
Answer: Technically speaking double wrapping you food would work, but it is often not a practical solution. A microwave heats the water molecules and causes more steam than a conventional oven. This rising steam causes pressure that is likely to rupture the seal and force or melt open the wrapping, which would render your lunch forbidden. Therefore I would not recommend its use.
