The technology may be new, but the concept is ancient. Today’s pop-up tops and shrink bands assure us that no one has tampered with our food or drink bottles. In the time of Judah Maccabee, clay seals did the trick.
Only special olive oil squeezed from the first drops of olives could be used to light the menorah in the Beit Hamikdash, the Holy Temple. This oil was made and stored in earthen vessels sealed with a special clay seal, guaranteeing their purity. Most artisans carved these seals out of stone and then pressed them into clay.
Clay seals played a crucial role in the miracle of Hanukkah. When the Maccabees returned to the desecrated Temple, they searched everywhere for oil to once again light the menorah. But all they could find were vessels with broken seals. Even if they contained oil, the broken seal meant that the oil was likely impure. To their great joy, one vessel was found with the seal still intact. It contained enough oil to light the menorah for one day, but God performed a miracle and the oil burned for eight days and nights.
You can use your stamp over and over again to make your personalized tamper evident seals. For example, put some objects in a shoe box, then put some clay over the spot where the box and lid meet. Press your stamp into the wet clay, then let it dry. Your box is now sealed and you’ll know right away if someone has tampered with it.
