How to minimize damage when opening heat affected parshiyos

I want to share a tip I learned many years ago regarding opening tefillin parshiyos that have been exposed to heat. As you open/ unravel the parshiyos, if you hear a crackling sound, as if the letters are sticking to the back of the klaf, this is a worry. Often this is an indication that the parshiyos have been exposed to heat, such as being left in a hot car on a hot day.

The way to deal with this is as follows: Stop opening the parshiyos immediately, as you could pull parts of letters off. Instead, hold either side of the parsha and bend the parsha back and fourth for a few seconds. When you continue opening the parsha, you should no longer hear the crackling sound because the bending back and forth movement should have "unstuck" the ink somewhat. It will no longer get pulled off as easily when you open the parshiyos.


  1. Question:
    Is it possible that such Tfillin are kosher before being checked, and then, they get damaged by the opening process?

    1. I have always wondered about this. I think that if the ink melts, and then gets stuck to the back of the klaf that is pressing against it, so much that it is adheased to the back more than to the front (so that when you open it, it stays on the back and is removed from the front) then this must be a problem, and this problem exists before opening. Also, often the ink swells from heat, making a shinuy tzurah i.e. kav moshuch. I see this all the time.
