I had those… I seem to remember they were unbreakable.
Those Corelle cups are made of a different ceramic material that the plates, bowls and saucers. The cups are opaque while the other pieces are translucent.
Have you tested any of these glass pieces, from the same sets?
Hi John, I have tested a lot of the dishwater from Corelle, they are my #SaferChoices pic! here are some of the links:

So your saying that these Corelle cups are toxic and you will ingest lead when using them?
Hi Aja! What I am doing is reporting the amount of lead in the paint / coating on these dishes. The amount of lead that is currently considered toxic in an item intended for children is 90 ppm or higher in the glaze. When these cups were made there was no regulatory standard for XRF detectable lead in the surface coating of dishware. No one has studied the potential harm that could be caused by pieces like this, BUT there was a study on glassware last year that you might find interesting: https://tamararubin.com/2017/11/decorated-glassware/
Unlike for other items, your testing report here does NOT indicate whether the test was of the colored paint or of the white background mug or both.
Please update this from your files. Some of us have the all-white versions and would like to know whether you tested the glaze of the whole cup in addition to the paint.
Usually you have published two sets of readings on your site: one for the paint and one for the background material, but here you are vague.
Also, does one assume that the beige Sandstone version of Corelle without paint is nevertheless a colored glass and therefore to be avoided?
Many thanks!
It’s the painted decorative edge. This study from England (from 2017) discusses the concern:

The plain (undecorated) white and sandstone tend to test negative for Lead and other toxicants.

Many thanks, Tamara. Now I can use my plain white ones in the microwave without worrying that I am poisoning myself!
I think these are made of Pyroceram whereas the ones with a hooked open handle I think are of Vitrelle.
Am I right? 😉
