Thank you for commenting on my ink article. In your comment you stated: "Many poskim disagree... Many rishonim have clearly stated the use of our ingredients." Would you please be kind enough to teach us (so I can include it in the article) which Poskim and what exactly and where did they say that the עפצים וקנקנתום type of ink is preferable over good quality דיו עשן that does not fail? We are not interested in biased פילפולים , or in those who said that דיו עשן is not being used because it fails easily or because it was not known how to make good quality דיו עשן. Nor are we interested in those who said to use עפצים וקנקנתום וגומא ואין לשנות when they discussed specifically the עפצים וקנקנתום type of ink. We are interested to find out where and who (if any) said explicitly, based on sources, that the עפצים וקנקנתום type of ink is preferable over good quality דיו עשן , even when there is דיו עשן of good quality that does not ...
Considering that the sefer is probably written in oak-gall ink, I'm not sure that that's a good first step. The ink is highly volatile and is as likely to flake off with the dust as not, as I've seen in some older sefarim and megillot in my schul.
ReplyDeleteHatzlocha rabba, though.
PS. Any photos of the k'tav?
DeleteI know that the Met does that all the time. I don't know if they'll work with private individuals though. My rebbi once mentioned to me that when he restored prewar scrolls (this was much closer to the war) he used a certain solvent which is now illegal because it depletes the ozone layer and managed to take of the dirt without the ink. I've been meaning to test some of the replacements for a while but I never got around to it.

Who is your rebbi where did he learn procedure from is it an old procedure how does it work
DeleteSorry about the delayed response. I tried twice but both times happened to be on a spotty internet connection and it didn't go through. My rebbi (for safrus) is Rabbi Menachem Mendel Schneider. He doesn't practice safrus fulltime and hasn't for many years. Apparently he learned it in the 70s from European sofrim who immigrated to the States after the war so it's old but not that old.
DeleteI'm not entirely sure how it works since I only have about 1.5 semesters of college chemistry but as I understand it, it's a polar solvent so it dissolves most of the compounds that make up "schmutz" but won't touch the iron based compounds that make up ink. We have at least 2 chemists in the forum who could explain better/correct me. As I said, I've never used it but I have used Everclear which also works.
What would you suggest is the best procedure to go about restoring .
ReplyDeleteWhen I rub it with eraser kesav is quite decent underneath and not as faded as it appears it has a lot of potential but must get rid of the dust and loose particles from the mashuach on the back.
front is not mashuach
Just use 92 percent rubbing alcahol. To look good you can repackage it and label it "Special solution "
