Ptil Tekhelet

Ptil Tekhelet — The Association for the Promotion and Distribution of Tekhelet — is a non-profit organization based in Israel. It provides educational programming and resources pertaining to tekhelet, and produces tekhelet for tzitzit. The association describes itself as comprised of a small group of individuals whose work is done lishma, for the express purpose of making tzitzit as the halakha requires. Its website offers an online store with pre-tied garments, strings, books and educational material, tying resources, an online library, and a speakers bureau offering lectures, workshops, discussions, and factory or beach tours in English, Hebrew and Russian. Ptil Tekhelet states it is under the strict supervision of Rabbi Avraham Rubin of Rechovot (Badatz Mehadrin), as well as Rabbi Eilyahu Tavger.

Ptil Tekhelet states that about 1300 years ago the secrets of Tekhelet — the blue color and the identity of the sea creature, the Chillazon, that produced the dye — were lost. Over the past half-century, according to the organization, a convergence of research and discoveries by rabbis, scientists, archaeologists and others led to the conclusive identification of the sea-snail Murex trunculus as the authentic source of Tekhelet. The organization's timeline page traces the dye industry from origins it places in Crete (1750 BCE), through ancient references such as the Tell-el-Amarna tablets (1500-1300 BCE) mentioning 'subatu sa takilti – a garment of tekhelet', the Tel Shikmona vat (circa 1200 BCE) whose dye stains were found molecularly equivalent to dye from Murex snails, Roman-era restrictions on dye use, and the Talmud (circa 550), which tells of tekhelet being brought from Israel to Babylon in the days of R. Ahai (506). Ptil Tekhelet — The Association for the Promotion and Distribution of Tekhelet — is described as a non-profit organization based in Israel that provides educational programming and resources pertaining to tekhelet and produces tekhelet for tzitzit. Its speakers bureau page identifies Dr. Ari Greenspan as a co-founder of the Ptil Tekhelet Association and Joel Guberman as co-founder and director, crediting Guberman with taking the initiative to organize the Ptil Tekhelet Foundation for the purpose of educating Am Yisrael about the newfound candidate for tekhelet and making the dye widely available.

A non-profit association dedicated to producing tekhelet for tzitzit and to educating the public about tekhelet, with its production under rabbinic supervision.
