MISSION STATEMENT
The Torah commands us to place strings of ציצית with a strand of Techeiles – תכלת (alternate spellings include: Techailes, t’cheiles, t’chelet, techelet and tekhelet and more…) upon our four cornered garments.
On this site we welcome you to explore the identity of the חלזון and תכלת, and the reason for its disappearance. We hope you will discover that today we can once again produce this ancient dye, and finally practice this long lost מצוה.
