Date: January 19, 2020 RH to IZ: I created a website called bluefringes.com … In earlier pictures it appears you are wearing Rambam or Raavad strings and switched later on? Or is it my imagination?

On Widespread Divisiveness on Tying Method and String Ratio 150 150 Israel Ziderman

Mixing Cuttlefish with Murex

Mixing Cuttlefish with Murex 150 150 Israel Ziderman

Date: May 19 MDR: Why not mix the Radzyner Rebbe’s cuttlefish and the murex to create a dye that satisfies both views?

Why the Murex Trunculus Snail Alone Can Be Used for Tekhelet 150 150 Israel Ziderman

Date: April 20, 2020 Israel Ziderman (IZ): Our source in the Tosefta is quite unambiguous: הביא מן החלזון כשרה שלא מן החלזון פסולה.
