It is not recommended to use chipped Pyrex for baking, microwaving, or cooking. The structural integrity of tempered glass is highly compromised by damage. When exposed to extreme temperature changes or pressure, a chip can easily turn into a crack, causing the dish to shatter or explode.
While Pyrex ovenware is a type of glass, it has been specially treated in the manufacturing process to withstand high temperatures, which makes it non-recyclable. Broken or chipped Pyrex should be disposed of carefully in the waste bin.

Yes, you should throw away or retire chipped plates. Using them poses a few risks, primarily because the protective, non-porous glaze is broken. Once the glaze is compromised, the exposed ceramic is porous, absorbing water and bacteria that are nearly impossible to wash out.
To test Pyrex for lead, use a home chemical swab test (like 3M LeadCheck Swabs). However, it's critical to know what you are testing. Clear, unpainted vintage and modern Pyrex glass is generally considered safe, but the painted exterior of vintage Pyrex bowls frequently contains very high levels of lead paint.
You can opt to tackle small nicks yourself with a crystal file, like the DMT Crystal Saver. These types of sharpeners work well to smooth any rough and chipped edges, providing an as-new finish.
Yes, many pieces of vintage Pyrex (particularly those manufactured before the 1980s) contain lead, primarily in the colored paint on the outside of the dishes.

How you handle old Pyrex depends entirely on its condition and value. For safety, always check for chips and remember to dispose of severely damaged or broken pieces in the regular trash, as they cannot be recycled.
Modern Pyrex isn’t as durable because the manufacturer switched the material from highly heat-resistant borosilicate glass to soda-lime glass. This change makes the bakeware much more susceptible to shattering from "thermal shock" (e.g., placing a hot dish on a cold counter).
The $67 Million Dry Cleaner Pants Suit is widely considered one of the stupidest and most absurd lawsuits in history. In 2005, a Washington, D.C. administrative judge, Roy L.
