If heated by boiling water or steam, without increasing the pressure,
it is unlikely that the temperature inside the cell will get to
boiling, resulting in few burst cells. Microwaving could continue
delivering heat well above the temperature of open boiling water, and
might easily result in ruptured cells. In this way, it may matter
where the heat comes from.
