justinhcase said:I have some quite large bit's of what I thought where industrial pyrex.
But they have the Corning stamp.
So am not sure of what they are and treat as normal glassware.
Those are corning. Well, in a sense... Corning bought qvf in 1973, then sold out in 95, and again in 2000 again, maintaining the name the whole time (qvf, i believe they lost the corning name in 95 or 98 when they sold that and of course their corningware branch in the states), qvf is in the euro market, england possibly?... But, it is pyrex.. Well, borosilicate glass, which is pyrex, and a host of other brand names such as Simax, Borcam, Borosil, Suprax, Kimax, Heatex, Pyrex, Endural, Schott, or Refmex, Kimble.(copy and pasted thst from wiki)
Corning has the original patent for pyrex glass in 1915. Now it isnt made of the same good stuff (some say its better now, some say the flip side), easy way to tell? Borosilicate is clesr, the soda-lime of today has a blue tint...world kitchen ruined everything corning built almost..
