Kiddush: Difference between revisions

# The cup should be a real metal or glass cup and not a plastic or paper cup. If nothing else is available, one should opt to use a plastic instead of a paper 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 differentiate between a cup that's reused and one that's ruined after it's first use, accordingly one could be lenient regarding plastic or paper. Even if you don't reuse it yourself, as long as it can be it is considerered a kli. The same law would apply for the cup used 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. see further: http://www.yutorah.org/lectures/lecture.cfm/727120/Rabbi_Aryeh_Lebowitz/kiddush_with_disposable_cups </ref>
