Ink that reappears!

By -
I have an interesting reoccuring problem. Every time I have to do a Mechika, although I use a #10 blade, an ink eraser, and sand paper, and it comes out perfectly white at that moment, the very next day, everything that was erased reappears as a shadowy image of all those letters. I know this has to do with some chemical reaction; I just don't know what to do to avoid this happening other then erasing the first time like I always do and then putting the sta''m aside until the next day and then erasing it again after it reappears, leaving it completely white as I want it. This is very impractical when trying to complete a pair of Tefillin. By the way, the ink I use is Nahari. If anyone has any advice, I'd be very grateful.

    What klaf are you using?

    What kind of "ink eraser"? The yellow eraser made for erasing Rapidograph ink (http://bit.ly/tjmkV8) has chemicals in it to dissolve the ink — it may be reacting with the klaf

    If you have the exact same problem with and without the eraser then it's probably not the eraser…

    It could be a problem with the combination of that particular ink and klaf. Did you try to contact the klaf manufacturer? They should be able to advise you — they may recommend a different ink. Even if they have no concrete advice, they should be alerted about the issue. They could try to recreate the problem and work towards a solution.

    Keep us posted!

    I contacted the Klaff manufacturer today. He has not heard of this problem before ( and it seems like no one either on this blog). He said he would discuss it with other customers to see if they have this problem. He advised me to scrape deeper into the Klaff. P.S. He himself is not a Sofer.

Ink, Kosher vs. non-Kosher

By -
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?

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
