Kluk Glass

שולחן ערוך אורח חיים הלכות פסח סימן תעב

הגה: ואין ליקח כוס שפיו צר כעין קלו"ג גלא"ז, מפני שלא יוכל לשתות רביעית כאחד

I purchased a beautiful wine glass for Pesach, however the mouth is a bit narrower than the rest of the glass- I was concerned that perhaps I have a Kluk glass that the Rama 472:15 recommends not to use.

From the internet I found out of something called Kluk Kluk decanter; “The sound the liquid makes as it comes out of the decanter resembles a cluck cluck sound”

Thus it is possible that the קלו"ק גלא"ז had a very narrow opening that produced a cluck cluck sound and my narrow glass is kosher.
