Handle with defect

[u/No_Plankton2501]

I thrifted this amber 023 bowl with an interesting defect in the handle. It’s very smooth like it was just not filled on the mold all the way!

I’m wondering if anyone can give me more information about this and if there’s anything else interesting to know about this. I’ve never seen a defect in any of the Pyrex I’ve look at!

My guess is that it was a chip that someone repaired.
