Which figure?
It is said the confirmed cases is more than 150,000, and some experts doubt the virus is from lab. It means it’s origin may be from bio-weapon.

Devitrification normally stops the glass being transparent.
It must have taken some clever work to get the crystals to have the same refractive index as the glass matrix.
you are right. what's the clever work to make it transparent ?

How can we possibly know if your mum's judgement on this is correct?
No.
It does not.
It can't.
Polypropylene does not contain nitrogen but "quaternary ammonium biocides and oleamide" do.
How do you know what propylene smells like?
Drp said, "Probably so small amounts as not to be harmful although you can almost always smell new plastics. The monomer is propylene I think (thus poly-propylene)."
so i guess it is the smell of propylene.
@ polypropylene doesn't contain nitrogen,.
Nobody says poly-propylene contain nitrogen. i am confused.
I and my mom both smell it like unpleasant chemical, and anything smells bad is not a good thing, maybe it is toxic, at least that bad smell makes people feel uncomfortable.

Thank you guys, I am relieved. it smells of propylene. I decide to let it lie in the sun for a few days.
