thank you for replying this quickly! its quite a reliefHello!
There is a tiny dent on the sleeve, so sand grain-sized piece of glass is somewhere in substrate.
If that's the only missing piece, I would not worry: odds of ingesting are very low.
Incandescent lamps don't have any hazardous substances inside, so substrate is not contaminated (in case with mercury-containing fluorescent lamps I would do a substrate change and more).
