Koshering Pyrex Utensils
Question
Can a meat Pyrex utensil that was mistakenly used for hot dairy be koshered? (Ashkenazi custom)
Answer
Shalom and blessings
Pyrex is glass.
According to the Ashkenazi custom, it absorbs and does not release, so koshering does not help.
According to the Sephardic custom, glass does not absorb at all. [Some are stringent with Pyrex, as it is not exactly glass].
