There is a wide range of
Judaica which employs Jewish designs and themes that
have developed over the centuries for use in the home
Passover Seder Plate Catalog
Judaica is generally items which display Jewish themes
and motifs. A cup for example my have a star of David
on it and be used as a wine cup on Shabbos. This cup
is now called a Kiddush cup.
Not all Judaica has a
religious use but can be solely decorative. An example
would be Jewish jewelry. The chai, hama, and
star of David are the most commonly used themes but
judaica is not limited to these motifs.
