Ptil Tekhelet provides genuine Tekhelet strings so Jews can once again fulfill the mitzvah of wearing Tekhelet on their Tzitzit.
About 1300 years ago, the secrets of Tekhelet, this wondrous blue color and the identity of the mysterious sea creature – the Chillazon – that produced the dye was lost. Over the past half-century, a convergence of research and discoveries by Rabbis, scientists, archaeologists, and others has led to the conclusive identification of the sea-snail, Murex trunculus, as the authentic source of Tekhelet.
תנו רבנן: הצד חלזון והפוצעו אינו חייב אלא אחת
(שבת ע”ה.)
The Rabbis taught: One who traps a Chillazon and breaks its shell to remove its blood for the dye is liable to bring only one sin-offering
(Shabbat 75a)
In honor of Daf Yomi reaching the sugya of Tzeida – Trapping on Shabbat and its connection to the Chillazon sea-snail, Ptil Tekhelet has collected sources that will help in understanding this topic. Click for articles and videos on the topic.
