If you honestly believe that you are wearing true tekhelet then you are not in violation of the Gemara (BM 61b). If your tekhelet turns out to be false tekhelet, then you will have only fulfilled the mitzvah of tzitzit but not the aspect of tekhelet, as the Gemara (Men. 40a) explains is the case for one who unwittingly wore kela ilan - see my article "False ...

The Rambam says that using the wrong techelet makes the tzitzit pasul. Additionally, if you don't use techelet at all you fulfill the mitzvah. Simply not a gamble worth taking - it's already a mitzvah in the bank.

The source for the Chilazon being in the Kineret is the Zohar, II, 48b, on parashat Terumah:
"And blue" (Shemot 25:3): Rabbi Yitzchak said: Blue [techelet] is from that fish that is in the Sea Genosar, WHICH IS THE SEA OF GALILEE, which is in the portion of Zvulon. This color is needed for the work of the tabernacle to show this color, AS IT IS ...

According to Wikipedia, Murex trunculus is found naturally around the entire Mediterranean Sea and Black Sea and on nearby coasts of the Atlantic, always in shallow water: seemingly, nowhere else.

They are slow to answer their email and sometimes hard to reach by phone. Ptil Tekhelet makes batches periodically and every batch comes out a slightly different shade of techeles. I don't think your scrap of fabric is such solid proof. Dyeing results vary, and just as the shade of techeles you get nowadays from Ptil Tehkelet varies from one batch to the ...

I can come up with a few reasons of why to only wear it on Shabbat.
You wear the best clothing on Shabbat. Techelet is Expensive, and to wear it every day might be too expensive to clean properly or to buy extra garments. However, on Shabbat you need to wear your best, so you buy a set of techelet for Shabbat.
They only bought one set of Techelet ...

הלכות קטנות לרא"ש (מנחות) הלכות ציצית סימן ו
ו תנן בראש התכלת [שם דף לח א] התכלת אינו מעכב את הלבן הלבן אינו מעכב את התכלת. פירש"י אף ע"ג דמצוה לתת ב' חוטי תכלת וב' לבן בציצית אפילו הכי אין זה מעכב את זה ואי עביד ארבעתן תכלת או ארבעתן לבן יצא ולכאורה הוי משמע דאין זה מעכב את זה היינו שאם הטיל ב' חוטין מין אחד יצא כי הא דתפילין של יד אינה מעכבת של ראש ושל ...

He says (Hil. Tzitzis 2:8) that in that case you can make the "white" strings any color except black, because that's too similar in color to techeles. (Kesef Mishneh there adds that according to this, using the actual color of techeles - whether the real stuff, or indigo - would also be no good.)

Thhe Rebbe Rashab wrote to R' Leiner (The original re-discoverer of techeiles [even though he was found to have been fooled by the scientists of his day, yet the reasons of the Rebbe Rashab still apply to the modern day tcheiles.]).

Here are short and long versions of an excellent class on the topic that goes through many arguments pro and con (with the speaker having an overall pro bias).

The Gemara (Bava Metzia 61b) speaks pretty harshly about "one who attaches kala ilan [indigo] to his garment and claims that it's techeiles." Since, as Shalom noted, the identity of techeiles is in fact uncertain (I've heard of at least three different opinions what creature it comes from), that may be reason enough to avoid using what might be the wrong ...

Two versions of Brisker Ravs response to Radziner Rebbe; one that's recorded in Radziner Rebbe's book is that there must be compelling archeological evidence that the tcheilis is indeed the correct version. Another verison passed down by word of mouth in the Soloveitchik family was that we lost the Mesorah. However, Rav Eliyashuv, in a letter adressed to his ...

They have some good evidence but there are also some issues. For example, why doesn't any earlier source mention that Techelet is from the same thing as Aragaman? It seems like a pretty basic thing that they should say when identifying the animal.
Another problem is how the Gemara's test (to make sure it wasn't indigo) would work if Techelet is chemically ...

Numerous points were made here which need to be answered:
(1) Regarding the reasons we believe that the Murex trunculus is indeed the hillazon of hazal, please see my latest article: http://tekhelet.com/pdf/TekheletThreadsOfReason.pdf
(2) Regarding the Arizal's statement that after the hurban habayit tekhelet is no longer available, please see my article: ...

One argument is from Chazal's silence regarding animal dyes. Chazal spend much time lambasting Kalei Ilan (the plant based indigo), but never once complain about a fake animal based indigo (by 'indigo' I mean a dye that is the right color and does not fade). So either there was only one animal based indigo dye and that was it, or there were others, but all ...

There's a new booklet being distributed (not very widely) by someone in Bnei Brak. In the front material has a very long letter by Rav Moshe Sternbuch shlita, which argues very strongly against bnei Torah wearing Ptil Tekhelet. Some of the reasons given sound a bit surprising to me (i.e. were beyond my limited understanding); one of them was this Zohar about ...

According to the Rambam, the tzitzit is passul if you use the wrong blue-dye for the techelet. (See my post here: http://judaism.stackexchange.com/a/8913/702)

I know a rabbi who only wears on Shabbat because he thinks it's a reasonable chumra but he doesn't want his kids to grow up thinking that we have a mesora for techelet so he only wears on his Shabbat/Yom Tov Tallit Gadol. As for why then, he said that Shabbat is a traditional time to be more makpid on certain chumrot (for instance, putting salt on the bread ...

The Rambam, in Hilchos Tzitzis (halacha 4) reads
ד התכלת, אינו מעכב את הלבן; והלבן, אינו מעכב את התכלת. כיצד: הרי שאין לו תכלת, עושה לבן לבדו; וכן אם עשה לבן ותכלת, ונפסק הלבן, ונתמעט עד הכנף, ונשאר התכלת לבדו--כשר.
The [absence of] techelet does not prevent [the mitzvah from being fulfilled with] the white strands, nor does the [absence of] the white ...

Rav Dov Lior rules to put Techeleth, he also rules to make double knot in the beginning and then to make ties by Rambam. I've heard this on his lesson on Mishna Berura where he showed his tzitzis tied this way.
From this I conclude that double knot is essential.

According to the Rambam, your tzizit can be any color really. The only thing they can't be is either all techelet, or techelet made from indidgo plants. (Some read this to mean any plants)
Since the Radzyner are made from animals and inorganic material but not plants, then this is not a problem.
I have heard some people say that you should put a bit of ...

There is a famous "brisker chumra" to be worried about the position of the Ba'al HaMa'or who said that tzitzit are only kosher if they have the blue and the white (just white is just not good enough) and refrain from wearing their tzitzit outside without an eruv as according to him, the tzitzit are invalid and you would thereby in fact be carrying the ...

For Ashkenazim I still can't find an answer to this Taana- Safek Deorayta LeHumra. If you are Ashekenazi then until I hear otherwise I think you should wear Tekhlet.
However, for Sephardim this isn't the case because the Techelet will only return at the time of the rebuilding of the bet hamikdash (see ben yohayada b"m 61b).
EDIT: I found an answer from the ...

I think the question is asked backwards.
Nothing is "universally accepted" unless you limit the meaning of "universe" to the groups of people you tend to agree with, or think have valid views.
The question to me, is for those who accept the new techelet. Why don't they pressure other Jews to wear them? Or, if offered a communal talit, why would most not ...
