Do aqua blue colored bottles contain manganese?

[Jimmy Langford]

I try not to expose manganese containing bottles that I don’t want to turn purple to sunlight when photographing them outside. I’m wondering if aqua blue bottles have manganese in them.

You don't need to worry about exposing bottles with manganese to sunlight during a photography session. It takes years before even the slightest purple tinge starts to form. You'd need to have them sitting out in the sun for half a century before you needed to worry about them going deep purple.
