... for chameitz. It is noted that he does not repeat the same thing
in YD. (Eg Peri Megadim (OC 451 MZ 31 "dad", YD 105 MZ 1 "ve'im").
The Minchas Yitzcoq (shu"t 1:86) therefore says that hag'alah would work
-- so not as meiqil as the Mechaber, but still, not keli chares.

The AhS YD 121:2 says that one may buy used glassware from a non-Jew
as long as they are washed and scrubbed well, "lefi shehein chalaqim
ve'einam bol'im".

I find no chiddush in R' Heineman holding like the AhS.

However, se'if 9 discussing cooking utensils says that keli zekhukhis ein
bahem tashmish bechamin. So if glass were usable as actual keli rishon
cookware, perhaps he would be machmir. But the AhS predated the common
use of pyrex and the like.

Tir'u baTov!
