Shalom aleichem: I am not familiar at all about this practice. what I have heard is that some follow the practice of the Maharm Ruttenberg not to wear tzitzit on shabbos out of the eiruv. The Netziv in his teshuvos Meisiv Dovor discusses the two different reasons given by different talmidim of the Maharam for…

Someone choosing to wear Radzyner Techeiles – R’ Benzion Halberstam

Someone choosing to wear Radzyner Techeiles – R’ Benzion Halberstam 150 150 rhecht

A: “It is the overwhelming consensus of Poskim Kadmonim that only Chilazon is kosher. The Radzyner Techailes isn’t from Chalazon, so it’s not kosher Techailes. I would give him some credit for perhaps intending to do a good thing, but he isn’t actually fulfilling the mitzva that way. It needs to be be Murex, which…

Can you explain the stages of the dye process, particularly, when the color takes effect? 150 150 rhecht

In order to get a first hand understanding of the dye procedure, I recommend getting one of our dye kits from our store. Basically, when the liquid comes out of the snail its a murky clear substance; in light and oxygen it slowly turn yellow, green, blue and finally settles at almost blackish purple. This…

Could you explain to why, in Talmudic times, did they have to do teima? Is it still necessary? 150 150 rhecht

“teima” refers to the procedure of taking a sample of the dye solution on to a test piece of wool to determine if the dye in the vat has reached the proper state to start dyeing wool. The need for such a procedure seems to indicate that vat dyeing was the method employed since in…

From the Rambam there is an understanding that there is no need for a particular species as long as the dye holds. There are, though, quite a few opinions how to interpret the words of Rambam. Are you aware of any other dye in this color family that meet this requirement and were available in the last 1000+ years?

There seems to be a machloket between Rashi and Rambam concerning the final color of tekhelet. Rashi (in the name of R. Moshe Hadarshan): midnight (dark) blue; Rambam: midday (light) blue. Is it possible to dye with the Murex to obtain both these shades, or only one?

You are correct that there is a machloket as to whether the color should be dark or light. Rav Yehuda Rock writes about this in his article in Techumin and his latest book called “Eved HaMelech” – you can see the relevant section in his article on our website (https://www.tekhelet.com/rak.pdf) see the bottom of p.17…

Rambam in Peirush HaMishnah writes that we can’t make tekhelet because of color uncertainties, contradictory to what he writes in Hil. Tzitzit. Using modern science we are able to compare it to indigo. My question: is there only one color that can be produced from the indigo plant, or is it possible to adjust it to darker/lighter hue by adding or subtracting amounts of indigo?

First of all, I believe it is fair to say that in a case of contradiction that you mention, we use the Rambam’s Mishnah Torah (Hilchot Tzitzit) for halachic decisions. To the best of my knowledge the indigo plants produce only one color – indigo. However this does not mean that we can’t produce different…

R. Eliyahu Tavger is the Rav of the Amuta. The workers doing the dyeing, spinning, twining of the threads are all yirei shamayim Jews who are very careful to state explicitly before every process, “L’shem mitzvat tzitzit.” – Mois Navon.
