Klaff Tanning question:
By
Rabbi Eli Gutnick
-
I received this question via email. I am not really a klaf expert, I was wondering if anyone could answer this question: Dear Rabbi Gutnick, I am writing to you because a good friend of mine has put the idea into my head that the klaf in my tefillin were not really tanned and therefore are not kosher. He referred me to Megilla 19a re diftera. From the research that I have done so far, it seems that the klaf that is used today is tanned only with a lime wash. On all of the tanning websites I’ve seen so far, they say that the lime doesn’t accomplish tanning but only the removal of the hair and some other pre-tanning effects. Would you be able to explain to me or refer me to a website that explains how the tanning process that is used today takes the hide out of the category of diftera? Thank you very much.
Ink, Kosher vs. non-Kosher

We all know that there is no ancient source that requires ink to be מן המותר בפיך . Possibly, as said here before, because in the olden days ink was always מן המותר בפיך and the question was never raised. It was probably self-evident. Nowadays, no decent Rav will approve an ink which is not מן המותר בפיך . Who was the first one to raise this question? Was it raised because of animal ingredients or because of non-kosher wine?

ReplyDeleteYou incorrectly described this as a teshuva. It is not. It is a peirush on a likut from Rav Ovadya by Rav Ovadia's son.
Also - did you actually read this?
He quotes an array of Sheelos UTeshuvos from both sides debating whether or not the paint (or the oil used in preparing the retzuos) must be min hamutar bficha. Some hold that it must be mutar b'ficha, but then explain why paint specific cases (ie. oil from a tamei fish) are mutar (i.e. the tamei ingredient is botel, etc). Others hold mutar b'ficha only applies to items from which you can tell their origin by looking at them (ie. the Shoel UMaishiv).
Furthermore- he says the same thing that I have been writing and that Rav Friedlander confirmed - milsa yeseira, items not intrinsic to the meleches shomayim, do not need to be mutar b'ficha. This is why some inks with treif ingredients may be mutar b'dieved or m'ikkar hadin mutar.
