> One thing I'm not aware of is if Pyrex or the other tempered glasses are safe or if they also contain plastic.
They're glass. They don't contain this. In particular, oven-safe glass is supposed to be of the borosilicate variety... but about 20 years ago manufacturing was moved to China (haha!). They're not properly formulated or tempered anymore, and in many cases not oven safe. They tend to shatter with large temperature changes, spilling hot casseroles over people who aren't in the habit of having steaming hot casserole showers and then complain about those.
> Just use metal wood or glass.
I like those materials, but think of the damage you're doing to the CPI with your advice. How would we combat inflation if we weren't able to constantly substitute in cheaper packaging materials and so forth?
