Rabbi Aryeh Lebowitz

That Svardim are totally meichel.

They assume that glass can never become treif because it's never boleah.

The mitziah seems to be like the Svardim.

And Ashkenazim or Machmir, that glass is boleah that has a din like klicheres.

There is a Sefer Zerah Emes, where he says that even according to the Ramah, we could be makled to use a glass dish for meat and then milk, because he points out that in Hilchas Tamyeinam, in Hilchas Ya'in Nesach, in Siman Kuflam and Hey Siv Chas, the Shulchan Aruch Paschins, that you're allowed to use a glass klee that Ya'in Nesach had been stored in, and the Ramah doesn't argue over there.

So why didn't the Ramah argue?

The Ramah should say glass is a big problem.

So he suggests in the Sefer Zerah Emes, that maybe there's no reason for Pesach and Shayim Mos Hashanah.

That when it comes to Pesach, it's a special chumar du chametz, that we assume glass becomes treif, but outside of chametz, we're meikel on glass.

That's what he suggests.

Rav Menashe Klein has a tshuva, Mishnah Lachos, where he says, yeah, yeah, that's true when that's the minag.

And the minag is by drinking glasses, that we use the same drinking glasses for fleishegs and milchegs.

And that's fine, to use the same drinking glasses by a flesh meal and a milich meal, because it's not Pesach, so we don't have the Chumar Dechametz, and Rav Rishon Amol Glass is not Baleah anyway, and drinking glasses are never a Kli Rishon to begin with, to really be Baleah.

How many hot, people usually don't drink, hot meat sauce.

from the drinking glasses.

They typically do not drink even hot coffees from their drinking glasses.

So the whole thing is such a far-fetched concern.

So he says, for drinking glasses, the minig is to be makled.

But, Ramin Asher Klein says, if you have a Pyrex dish, Pyrex is glass.

It's a new type of glass.
