Kiddush: Difference between revisions

# Some authorities say that one may not use a plastic or paper cup for [[Kiddish]], however, many authorities permit but agree that it's preferable to use a real cup. <ref> Sh"t Igrot Moshe O"C 3:39 forbids using a plastic or paper cup as they aren't considered a nice cup and it's worse off than a broken cup (which is forbidden by S"A 183:3. Mishna Berura 183:11 says that even if it is just the base that is cracked one should still be strict.) The Radiance of [[Shabbos]] (page 44) points out that this doesn't depend on the quality of the plastic at all. Sh"t Tzitz Eliezer 12:23 differentiates between a cup that would be used for hot liquids and could be reused and one that's ruined after it's first use. Even if one personally doesn't reuse it, it is still considered a kli. This is true for kiddush, [[havdala]], and [[netilat yadayim]]. Sh"t Beer Moshe 5:55 on the other hand, only allows cup that are commonly reused and therefore only permits plastic cups and not paper cups, or small shot glasses because those are rarely reused. Sh"t Az Nidabru 6:49 is the most lenient allowing any disposal cup, however, it's still preferable to use a better cup as a hidur mitzva. Shevut Yitzchak (vol 1, 4:5, pg 48) in name of Rav Elyashiv and Chazon Ovadyah ([[Shabbat]] vol 2) concur with the lenient opinion.

Although many poskim, say that using two plastic cups doesn't help at all, see [http://www.yeshiva.org.il/ask/?id=62394 Rav Dov Lior] for the explanation of it, though he writes that he doesn't necessarily think that it helps the issue.  </ref>
