Klaff Tanning question:
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.
The forum is back online...for reference and research purposes.
Dear Readers and Members, The forum has been down for over 6 months because the domain name (www.stamforum.com) lapsed and it is no longer available to re purchase. Although this forum is now defunct (it has morphed into several whatsapp groups), I have had many requests to put it back online because it contains so much information (over 1,800 posts and thousands of comments in the discussions, on a wide range of topics related to STa"M). I have therefore put the forum back online at blogger, so the address is www.stamforum.blogspot.com. The forum lasted for a decade...not a bad effort! It was pretty popular back in the days before whatsapp and managed to receive over a million hits in it's short life. It was one of the only organised forums in the STa"M world and definitely the largest in it's heyday. I would like to thank all those who cobtributed over the years, particularly the early members who helped build it up. Thanking you all, Eli
2 questions
ReplyDeleteIt says that it stays firm after letting it dry for 2 weeks, what exactly does that mean? after doing a fix can one roll the parshiyos within the same day?
The Shavet Halevy wrote, that the diyo is in the geder of ktav yachol limchak that is mentioned in the Rambam...
If I understand correctly this refers to how it can erase in water (similar to parshas sotah)
How is this so since it is water proof?
Thanks
1. In the instructions we explain that Dio Lanetzach dries in 3 steps.
Delete10-20 minutes: dry to the touch.
24 hours: can fold parshiot shel rosh and roll a mezuzah.
3 weeks: can make "torture" experiments to test the strength of the ink.
After making a small correction on tfillin or mezuzah (which never includes a large area of ink) you can wait at least one hour for regular drying, then use a warm hair drier for a few minutes to speed up the drying. NEVER use a hair dryer on wet ink.
2. Regarding megilat sotah, I copied the section that explains it from diolanetzach.com:
יש טעות נפוצה לפיה סוברים שדיו סת"ם צריך שימחה במים. במגילת סוטה כתוב: "ומחה אל מי המרים" - לא מחה במים אלא מחה אל המים. קודם מחה את הדיו ואחר כך נפל הדיו המחוי אל המים. הרמב"ם כותב: "אינו כותבה לא בקומוס ולא בקנקנתום ולא בכל דבר שרישומו ניכר ועומד אלא בדיו שאין בו קנקנתום ... נשאר במגילה רושם כתב ניכר, פסולה עד שימחוק יפה יפה... כתב אות אחת ומחקה וחזר וכתב אות שנייה ומחקה עד שהשלים, פסולה עד שתהיה כולה כתובה." (הלכות סוטה, פרק ד). מכיוון שאי אפשר לחזור ולכתוב על מגילה רטובה אחרי מחיקה במים, אנו למדים שהמחיקה היתה ע"י גרוד יבש ולא ע"י שטיפה במים. רק דיו שאפשר למחוק יפה יפה בגרוד יבש בלי רושם כתב, כשר למגילת סוטה. דיו עפצים וקנקנתום פסול למגילת סוטה. (משנה, סוטה, פ'ב, מ'ד) כי "רישומו ניכר מאד ואינו נמחק לגמרי" (שו"ע הרב, לב, ד). י
דיו סת"ם חייב להיות כזה שגם "יתקיים אלפי שנים" (שו"ת הרמב"ם, קלו) וגם אפשר למחקו מחיקה נקיה "שאם תמחקנו יהיה נמחק" (רמב"ם, הלכות תפילין, א, ד), לא מחיקה במים אלא ע"י גירוד יבש בסכין.
Zvi, do you have a list of places that sell your Dyo in Israel? I used to see it at all the klaf places in Jerusalem. Now most of them only carry the ink for rapidiograph. I would like to try it out.
