The first definitive proof of production of the ancient blue dye “tekhelet” in Israel was revealed during an Israel Antiquities Authority presentation at a Jerusalem conference.

Derived from shellfish, tekhelet is mentioned in the Torah as the dye used in the clothing of the High Priest in the Jerusalem Temple, as well as being mixed in with white in the fringes of the tzitzit garment. But the origins of tekhelet were lost after the Roman exile, and most tzitzit fringes today are colored exclusively white. Over the past century, experts—including the late Chief Rabbi Dr. Isaac Herzog—have attempted to rediscover the origins of the dye, tracing it to the hillazon snail.

“Until now, our most important discovery had been the piles and piles of murex trunculus (hillazon snail) shells from the area, which served as a silent testimony to the presence of an ancient dyeing industry in Israel,” said Dr. Naama Sukenik, a researcher at the Israel Antiquities Authority.

“But this newest finding from the times of Bar Kokhba—sky blue fabric from the Dead Sea region—is definitive proof of both a colored fabrics trade and strict adherence to the biblical commandment of tekhelet in ancient Israel,” Sukenik said.

The new evidence was presented at the “100 Years to Tekhelet Research” conference sponsored by Ptil Tekhelet, which was attended by more than 350 scientists, academics, and rabbinic scholars.

    It is common knowledge that murex was used for dyeing Argaman (purple), so “piles and piles of murex trunculus (hillazon snail) shells” is an indication of an ancient dyeing industry in Israel, but is not connected to using Murex for tekhelet on tzitzit.

    The sample that Naama Sukenik presented was not a talit with tekhelt tzitzit.

    Rabbi Zalman Schachter-Shalomi is correct, the Radziner rebbe pioneered the recovery of tekhelet for our time and his chilazon may indeed be the authentic chilazon.

    In his book ” Phoenicia, History of a Civilization ” George Rawlinson wrote several pages about using the Murex trunculus and the Buccinum lapillus snails to make blue and purple dyes by the Phoenicians. He wrote the book in…1889.

    You need to mention the work of Rabbi Gershon Henoch Lajner, the Radziner rebbe who pioneered the recovery of techelet for our time
